Floors of the pharynx The pharynx is the crossroads of the respiratory and digestive tracts. The lower border of the pharynx is the place of its transition into the esophagus at the level of the 6th cervical vertebra. There are three sections of the pharynx: Upper - nasopharynx Middle - oropharynx Lower - hypopharynx The pharynx connects the cavities of the nose and mouth above, with the larynx and esophagus below. The pharynx is formed by muscles, fibrous membranes and is lined inside with a mucous membrane. The length of the pharynx of an adult from its arch to the lower end is 14 cm (12-15), the transverse size is on average 4.5 cm.

Sagittal section of the pharynx 1. Hard palate; 2. Soft palate; 3. Uvula; 4. Pharyngeal opening of the auditory tube 5. Pharyngeal tonsil; 6. Palatine tonsil; 7. Palatoglossus and velopharyngeal arches; 8. Lingual tonsil; 9. Pear-shaped pockets; 10.Epiglottis;

Pirogov-Waldeyer Lymphadenoid pharyngeal ring Pirogov-Waldeyer. I and II - palatine tonsils III - nasopharyngeal IV - lingual V and VI - tubal In addition, there is an accumulation of lymphadenoid tissue on the posterior wall of the pharynx, in the area of ​​the lateral ridges and the lingual surface of the epiglottis.

Classification of sore throats according to B.S. Preobrazhensky Catarrhal Catarrhal Follicular Follicular Lacunar Lacunar Fibrinous Fibrinous Herpetic Herpetic Ulcerative-necrotic (gangrenous) Ulcerative-necrotic (gangrenous) Phlegmonous (intratonsillar abscess) Phlegmonous (intratonsillar abscess) Mixed forms Mixed forms

Pharyngoscopy for catarrhal tonsillitis During pharyngoscopy, the tonsils are somewhat swollen, very red, their surface is covered with mucous discharge. The mucous membrane around the tonsils is more or less hyperemic, but there is no diffuse hyperemia of the oropharynx, which is characteristic of acute pharyngitis. In more severe cases, there are pinpoint hemorrhages in the mucous membrane.

Pharyngoscopy for lacunar tonsillitis On the swollen and reddened mucous membrane of the tonsils, white or yellow plugs consisting of bacteria, sloughing epithelial cells and a large number of leukocytes form from the depths of the tonsils of new lacunae. A yellowish-white coating often forms on the surface of the tonsils, which does not extend beyond the tonsils. With lacunar tonsillitis, the entire tissue of the tonsil is affected, which, as a result, swells and increases in volume. The formation of plaque in the lacunae distinguishes this form from diphtheria, in which, in addition to the lacunae, the convex places of the mucous membrane of the tonsil are also affected.

Pharyngoscopy for follicular tonsillitis On the reddened and swollen mucous membrane of both tonsils, a significant number of round, pinhead-sized, slightly raised yellowish or yellowish-white dots appear, which represent suppurating follicles of the tonsils. The yellowish-white dots, gradually increasing in size, suppurate and open.

Pharyngoscopy for phlegmonous sore throat: Sharp bulging of the tonsil, palatine arches and soft palate towards the midline (spherical formation on one side of the pharynx), the tongue is displaced to the opposite side, tension and bright hyperemia of the bulge, in the area of ​​greatest protrusion when pressed there is fluctuation, the tongue is covered with a thick coating and viscous saliva.

Retropharyngeal abscess When examining the posterior wall of the pharynx or palpating it with a finger, a vapor-like protruding, fluctuating tumor is determined. The abscess can spread to the area of ​​the large vessels of the neck or descend along the prevertebral fascia into the chest cavity and cause purulent mediastinitis.

Classification of chronic tonsillitis (according to Preobrazhensky - Palchun) Chronic tonsillitis Simple form Concomitant diseases Toxic-allergic form I - degree Concomitant diseases II - degree Concomitant diseases Associated diseases

Diagnostic endoscopic examination makes it possible to make a diagnosis, verify it morphologically, assess the extent of the process and develop optimal treatment tactics. Thanks to the constant improvement of endoscopic equipment and auxiliary endoscopic instruments, as well as the development and implementation of new treatment methods, many diseases can be treated through an endoscope. Also, if necessary, you can take a small piece of tissue for examination - a biopsy.

Slide 3

To study different organs, various endoscopic techniques are used:

Laryngoscopy – to examine the larynx Otoscopy – to examine the external ear Rhinoscopy – to examine the nasal cavity.

Slide 4

Laryngoscopy

Laryngoscopy is a method of visual examination of the larynx. There are indirect, direct, and retrograde laryngoscopy. This technique is performed to examine the larynx during diagnostic and therapeutic measures. Indirect laryngoscopy is performed on adults and older children using a special mirror; a headlamp or a reflector that reflects the light of a lamp is used for lighting. In direct laryngoscopy, a laryngoscope is inserted into the patient's mouth. Due to the tilting of the head, a straightening of the angle between the axis of the oral cavity and the axis of the laryngeal cavity is observed. Thus, the doctor, pushing back the tongue with the laryngoscope blade and illuminating it with a flashlight built into the laryngoscope, can directly observe the inside of the larynx with his eyes.

Slide 5

The laryngoscope is a lightweight (weighing ~ 110 grams), portable optical device, specially designed for performing ETT through the glottis with minimal risk to the patient. This device allows you to visually monitor the progress of intubation using an optical system built into the device body. At the end of the laryngoscope blade there is a low-temperature LED. The device is also equipped with an anti-fog system for the optics - for complete visual control of the progress of intubation.

It is also possible to monitor the intubation process on a wireless monitor, the image of which comes from a portable wireless video camera attached to the laryngoscope body, which can be connected to any external monitor or PC.

Slide 6

Direct laryngoscopy Areas of application of the optical laryngoscope

Obviously complicated laryngoscopy. Patients at increased risk of difficult intubation Emergency situation when direct laryngoscopy fails Tracheal intubation of the conscious patient. Patients with cervical spine immobilization (Anesthesiology 2007;107:53-9). Patients with infectious diseases (Internet Journal of Airway Management). Assistance with tracheostomy Patients with ischemic heart disease and arrhythmias Patients with polytrauma. Emergency and prehospital laryngoscopy Patients requiring intubation in a sitting position. Replacement of ETT in seriously ill patients with difficult intubations. Installation of double-lumen endobronchial tubes in ENT patients. Installation of fiberscope and gastroscope. Fibroscopy training. Removal of foreign bodies.

Slide 7

Otoscopy is an examination of the external auditory canal, the eardrum, and if it is destroyed, the tympanic cavity using special instruments. Under the control of otoscopy, ear toilet is performed, foreign bodies, polyps and granulations are removed, as well as various operations - paracentesis, tympanopuncture.

Slide 8

A modern otoscope is a small optical system with an illuminator and a funnel, placed on a detachable handle. There are diagnostic and operating otoscopes, the design of which has open optics and allows the use of various ENT instruments for medical procedures. For doctors practicing on the road, manufacturers have developed a pocket otoscope. This is a fully functional portable otoscope with smaller dimensions and weight, easily fits into a pocket and is secured in it using a reliable clip on the handle. Modern technologies make it possible to install a miniature video camera into the otoscope body. Video otoscopes are connected to various types of monitors and allow the doctor not only to perform an examination, but also to demonstrate the image to colleagues, medical students or the patient.

Slide 9

Rhinoscopy is an instrumental method of visual diagnostic examination of the nasal cavity using nasal dilators, a nasopharyngeal speculum or other devices.

In medicine, it is customary to distinguish three main types of rhinoscopy: anterior, middle and posterior rhinoscopy. Anterior rhinoscopy is performed using a nasal speculum. This procedure allows the doctor to examine the anterior and middle parts of the nasal cavity for the condition (normal or abnormal/modified). Middle rhinoscopy is an examination by a doctor, first of all, of the middle nasal passage, as well as the upper parts of the nasal cavity. It is carried out using a nasal speculum with elongated nasal dilators. Posterior rhinoscopy is designed to examine the condition of the posterior sections of the nasal cavity

Slide 10

A rhinoscope is an endoscopic instrument for examining the condition of the mucous membrane and searching for pathologies in almost any part of the nasal cavity, which makes it more effective than a traditional examination.

Slide 11

Rhinoscope design

The design of the rhinoscope consists of an outer tube and an ocular head, consisting of a body, a light guide connector and an eyecup. Modern rhinoscopes are equipped with optical tubes with an expanded field of view, which work both visually and in conjunction with an endovideo system. The use of new optical technologies in the manufacture of lenses and the coating of optical surfaces makes it possible to achieve high light transmission and uniform light distribution. As a result, the doctor receives a detailed and detailed image of the nasal cavity and can act more accurately and confidently.

Slide 12

Emergency conditions in otolaryngology:

bleeding from the upper respiratory tract, nasal boil, laryngeal stenosis, laryngeal diphtheria, foreign bodies in the respiratory tract, acute stenosing laryngotracheitis, chemical trauma of the esophagus, otogenic and rhinogenic intracranial complications.

Slide 13

Nosebleed.

Causes: Local: traumatic injuries rank first among local causes of nosebleeds, atrophic rhinitis, nasal polyposis, angiofibroma of the nasal septum, juvenile angiofibroma of the nasopharynx, malignant neoplasms of the nasal cavity; General causes include changes in the vascular wall and blood composition that are observed with : - infectious diseases; - liver diseases (hepatitis, cirrhosis); - diseases of the blood system).

Slide 14

Treatment of nosebleeds

First aid: - measuring blood pressure; - place the body in a horizontal position with the head end elevated; - apply an ice pack to the bridge of the nose and the back of the head; - local measures: insert a tampon with hydrogen peroxide into the nasal cavity while pressing the wing of the nose; cauterization of the bleeding area with 10-40% lapis solution; cryotherapy; anterior and posterior tamponade; ligation of the external carotid artery. - general medications: hypotensive; coagulants - decinone, etamsylate (from 1 to 4 ml); factors that improve blood clotting: calcium chloride 20ml; calcium gluconate; fibrinogen (200ml); fibrinolysis inhibitors: aminocaproic acid (200 ml intravenously), gordox; blood components: platelet mass, whole blood; vitamins: ascorbic acid, vikasol (Vit.K).

Slide 15

Bleeding from the pharynx, larynx, trachea

The source of hemoptysis can be varicose veins of the pharynx, lingual tonsil, larynx and trachea, especially in the elderly, in patients with heart defects, lung disease, liver cirrhosis, chronic nephritis. Hemophilia and other blood diseases are often accompanied by bleeding and hemoptysis from the pharynx, larynx and trachea. Moments that contribute to bleeding are severe coughing, expectoration, and physical stress.

Slide 16

Treatment

The main thing is to provide the patient with rest. It is necessary to place the patient in bed in a sitting position on the floor (with his head elevated). For bleeding from the pharynx and trachea, silence, cold or lukewarm food, swallowing pieces of ice, fresh air, and hemostatic therapy if necessary are recommended. Only for very serious bleeding, when general treatment is ineffective, may a tracheotomy or laryngotomy be required, followed by tamponade of the larynx or trachea .

Slide 17

Nasal boil

purulent-necrotic inflammation of the hair follicle, adjacent sebaceous gland and fiber. The widespread involvement of surrounding tissues in the inflammatory process is a qualitative difference between a boil and ostiofolliculitis, which is close to it in etiology and pathogenesis. Due to the peculiarities of the venous system of the face and the likelihood of rapid development of cavernous sinus thrombosis. A nasal boil, unlike other localizations, is a dangerous and alarming disease. The boil is localized on the tip and wings of the nose, in the vestibule, near the septum and the bottom of the nose. Gradually increasing redness of the skin and painful infiltration of soft tissues appear.

Slide 18

Treatment. Treatment depends on the severity of the disease: 1) Outpatient for uncomplicated course: UV irradiation, UHF, ichthyol, tetracycline ointment, indirect anticoagulants (aspirin). 2) Hospitalization: in children; in the presence of septic manifestations; for symptoms of inflammation (thrombosis) of the facial vein. Therapy: opening of the abscess, antibacterial therapy, direct anticoagulants (heparin) under the control of the blood coagulation system.

Slide 19

Laryngeal stenosis

Laryngeal stenosis is a narrowing of the lumen of the larynx, leading to difficulty breathing through it. According to the time of development, the following forms of stenosis are distinguished: Fulminant (develops within a few seconds, minutes, for example, during aspiration of a foreign body); Acute (develops within several hours, up to a day ); Subacute stenosis (develops within a few days, up to a week) - with diphtheria, trauma, chondroperichondritis of the larynx, paralysis of the recurrent laryngeal nerves; Chronic (several months) develops with tumors and infectious granulomas of the larynx. Treatment. Stages 1 and 2 – conservative; Stage 3.4 – tracheostomy, conicotomy. Conservative treatment: glucocorticoids, antihistamines, glucose 40% IV, diuretics.

Slide 20

Diphtheria of the larynx

The larynx is affected by diphtheria in combination with diphtheria of the pharynx and nose. Routes of infection: airborne; household or alimentary. The clinic is determined by the development of acute laryngeal stenosis. Diphtheria is characterized by a triad of symptoms: difficulty breathing, change in voice up to aphonia, cough corresponding to the voice. Treatment - Hospitalization in the infectious diseases department. - Early administration of anti-diphtheria serum. - Correction of cardiovascular and renal disorders. - Detoxification. - Intubation or tracheostomy for decompensation of stenosis.

Slide 21

Acute stenosing laryngotracheitis or croup

is the most common cause of acute laryngeal stenosis in children. Acute laryngotracheitis syndrome is characterized by three leading symptoms: - stenotic breathing; - barking cough; - change in voice. With the development of acute laryngeal stenosis, the following agents are recommended: glucose solution 20% -20 ml; calcium chloride solution 10% -0.2 ml per 1 kg of body weight; aminophylline solution 2.4% -2-3 mg per 1 kg of body weight; diphenhydramine solution 1% -1ml; prednisolone solution 2-3 mg per 1 kg of body weight. If conservative treatment is ineffective, prolonged intubation is recommended, followed by tracheostomy.

Slide 22

Foreign bodies of the trachea and bronchi

Inspection of the trachea - upper tracheostomy + bronchoscopy Foreign bodies of the bronchi Treatment: Delivery by car SP in a sitting position, if necessary mechanical ventilation, cardiovascular drugs, tsititon, oxygen inhalation.

Slide 23

Chemical trauma to the esophagus

Emergency assistance at the scene of the incident. - Analgesics and narcotics intramuscularly: induce vomiting, rinse the stomach through a thick tube (4-10 l) with a solution of bicarbonate of soda, burnt magnesia. - Respiratory and cardiac analeptics: caffeine, cordiamine, camphor. At the hospital stage (surgery department, intensive care department, intensive care department). Fight against shock (analgesics, antispasmodics, sedatives). Elimination of acidosis. Prevention and treatment of renal failure and toxic hepatitis. Treatment of burns of the respiratory tract. Treatment of purulent complications.

Methods of examination and examination of ENT organs have a number of general principles.
The subject sits so that the source
lights and a table with tools
to his right.
The doctor sits opposite the patient,
placing your feet on the table; legs
the subject should be outward.
The light source is placed at the level
right auricle of the subject in
10 cm from her.

1) Inspection of the external nose and projection sites of the paranasal sinuses
on the face.
2) Palpation of the external nose: index fingers of both hands
placed along the back of the nose and lightly massaging
movements palpate the area of ​​the root, slopes, back and
tip of the nose.
3) Palpation of the anterior and lower walls of the frontal sinuses: large
place the fingers of both hands on the forehead above the eyebrows and gently
press on this area, then your thumbs
moved to the area of ​​the upper wall of the orbit to the inner
corner and also press. The first exit points are palpated
branches of the trigeminal nerve (n. ophthalmicus). Palpation is normal
the walls of the frontal sinuses are painless (Fig. 1.2).
4) Palpation of the anterior walls of the maxillary sinuses: large
the fingers of both hands are placed in the area of ​​the canine fossa on
anterior surface of the maxillary bone and slightly
press. The exit points of the second branches are palpated
trigeminal nerve (n. infraorbitalis). Palpation is normal
the anterior wall of the maxillary sinus is painless.
Palpation of the walls of the frontal sinuses

5) Palpation of the submandibular and cervical lymph nodes:
submandibular lymph nodes are palpated at several
with the head of the person being examined tilted forward with light massaging
movements of the ends of the phalanges of the fingers in the submandibular region in
direction from the middle to the edge of the lower jaw.
The deep cervical lymph nodes are palpated first from one
side, then on the other. The patient's head is tilted forward (with
tilting the head posteriorly, anterior cervical lymph nodes and main
the vessels of the neck are also displaced posteriorly, which makes them difficult to feel).
When palpating the lymph nodes on the right, the doctor’s right hand lies on
crown of the subject, and with the left hand they massage
movements with soft deep immersion into the tissue by the ends of the phalanges
fingers in front of the anterior edge of the sternocleidomastoid
muscles. When palpating the lymph nodes on the left, the doctor’s left hand
is located on the crown, palpation is performed on the right.

Examination of the nasal cavity is carried out when
artificial lighting (frontal
reflector or stand-alone
light source) using the nasal
speculum - nasal dilator,
which must be held in the left
hand as shown
Anterior rhinoscopy:
a - correct position of the nasal dilator in the hand;
b - position of the nasal dilator during examination

Rhinoscopy can be anterior, middle and posterior.
1) Inspection of the nasal vestibule (first position during anterior rhinoscopy).
Using the thumb of the right hand, lift the tip of the nose and inspect
vestibule of the nose. Normally, the vestibule of the nose is free and there is hair.
2) Anterior rhinoscopy is performed alternately - one and the other half
nose A nasal dilator is placed on the open palm of the left hand with its beak down;
the thumb of the left hand is placed on top of the nasal dilator screw,
index and middle fingers - outside under the jaw, IV and V should
be between the branches of the nasal dilator. Thus, fingers II and III
close the jaws and thereby open the beak of the nasal dilator, and IV and V
the fingers spread the jaws and thereby close the beak of the dilator.
3) The elbow of the left hand is lowered, the hand with the nasal dilator should be
mobile; The palm of the right hand is placed on the parietal area of ​​the patient so that
give the head the desired position.

4) The beak of the nasal dilator in a closed form is inserted 0.5 cm into the vestibule of the right half of the nose
sick. The right half of the nasal dilator beak should be in the lower inner corner
vestibule of the nose, left - on the upper third of the wing of the nose.
5) Using the index and middle fingers of the left hand, press the branch of the nasal dilator and
open the right vestibule of the nose so that the tips of the beak of the nasal dilator do not touch
mucous membrane of the nasal septum.
6) Examine the right half of the nose with the head in a straight position; the color of the mucous membrane is normal
the shell is pink, the surface is smooth, moist, the nasal septum is in the midline. Normal
the nasal turbinates are not enlarged, the common, lower and middle nasal passages are free. Distance
between the nasal septum and the edge of the inferior turbinate is 3-4 mm.
7) Examine the right half of the nose with the patient’s head slightly tilted downwards. At
This clearly shows the anterior and middle sections of the lower nasal passage and the bottom of the nose. Normal
the lower nasal passage is free.
8) Examine the right half of the nose with the patient’s head slightly tilted back and to the right.
In this case, the middle nasal meatus is visible.
9) With fingers IV and V, push back the right branch so that the nose of the beak of the nasal dilator does not
closed completely (and did not pinch the hairs) and remove the nasal dilator from the nose.
10) Inspection of the left half of the nose is carried out in a similar way: the left hand holds the nasal dilator, and
the right hand rests on the crown of the head, while the right half of the nasal dilator beak is in
the upper inner corner of the vestibule of the nose on the left, and the left one in the lower outer corner.

1) There are a large number of methods for determining
respiratory function of the nose. The simplest method is V.I. Vojacek,
at which the degree of air permeability through
nose. To determine breathing through the right half of the nose
press the left wing of the nose to the nasal septum
index finger of the right hand, and with the left hand they bring
a fluff of cotton wool to the right vestibule of the nose and ask the patient
take a short breath and exhale. Nasal is determined similarly
breathing through the left half of the nose. According to the deviation of the fleece
The respiratory function of the nose is assessed. Breathing through each
half of the nose may be normal, obstructed or
absent.

2) The determination of the olfactory function is carried out in turn for each
half of the nose with odorants from the olfactometric kit
or using a device - an olfactometer. To determine
olfactory function on the right is pressed with the index finger
with the right hand the left wing of the nose to the nasal septum, and with the left hand
take a bottle of odorous substance and bring it to the right vestibule
nose, ask the patient to inhale with the right half of the nose and
determine the smell of a given substance. The most commonly used substances
with odors of increasing concentration - wine alcohol, tincture
valerian, acetic acid solution, ammonia, etc.
The sense of smell is determined through the left half of the nose
similarly, only the right wing of the nose is pressed with the index
finger of the left hand, and with the right hand bring the odorous substance to the left
half of the nose. The sense of smell may be normal (normosmia),
decreased (hyposmia), absent (anosmia), perverted
(cocasmia).

Radiography. She is one of the most
common and informative methods
examination of the nose and paranasal sinuses.
The following methods are most often used in the clinic.
With a nasofrontal projection (occipito-frontal) in
the patient's head is placed in a lying position
so that the forehead and tip of the nose touch the cassette. On
the resulting image best shows the frontal and
at least ethmoid and maxillary sinuses

With a nasomental projection (occipitomental)
the patient lies face down on the cassette with his mouth open, touching
nose and chin towards her. In this photo you can clearly see
frontal, as well as maxillary sinuses, cells of the ethmoid
labyrinth and sphenoid sinuses (Fig. 1.4 b). In order to
see on the x-ray the level of fluid in the sinuses,
use the same styling, but in a vertical position
patient (sitting).
With lateral (bitemporal), or profile, projection of the head
the subject is placed on the cassette in such a way that
the sagittal plane of the head was parallel to the cassette,
The X-ray beam passes in the frontal direction slightly
anterior (1.5 cm) from the tragus of the auricle.

Most common
x-ray placements,
used for
study of paranasal
sinuses:
a - nasofrontal (occipital-frontal);
b - nasomental
(occipitomental)

c - lateral (bitemporal,
profile);
g - axial
(chin vertical);
d - computer
tomogram of the paranasal
sinuses

With the axial (chin-vertical) projection of the patient
lies on his back, throws his head back and the parietal part
placed on the cassette. In this position, the chin
the area is in a horizontal position and the X-ray
the beam is directed strictly vertically to the thyroid notch
larynx. In this arrangement wedge-shaped
sinuses separately from each other (Fig. 1.4 d). In practice, like
Typically, two projections are used: nasomental and
nasofrontal, if indicated, other styling is prescribed.
In the last decade, widespread
methods of computed tomography (CT) and magnetic nuclear
resonance imaging (MRI), which have much larger
resolving capabilities.

These methods are the most informative
modern diagnostic methods with
the use of optical visual systems
control, rigid and flexible endoscopes with
different viewing angles, microscopes.
The introduction of these high-tech and
expensive methods has significantly expanded
horizons of diagnostics and surgical
capabilities of an ENT specialist.

1. Examine the neck area and the mucous membrane of the lips.
2. Regional lymph nodes of the pharynx are palpated: submandibular, in
retromandibular fossae, deep cervical, posterior cervical, supra- and
subclavian fossae.
Stage II. Endoscopy of the pharynx. Oroscopy.
1. Take the spatula in your left hand so that your thumb supports the spatula
from below, and the index and middle (possibly ring) fingers were on top. Right
the hand is placed on the crown of the patient.
2. Ask the patient to open his mouth, use a spatula to pull the left and
right corners of the mouth and examine the vestibule of the mouth: mucous membrane, excretory
ducts of the parotid salivary glands located on the buccal surface at the level
upper premolar.
3. Examine the oral cavity: teeth, gums, hard palate, tongue, excretory ducts
sublingual and submandibular salivary glands, floor of the mouth. The floor of the mouth can be
examine by asking the person being examined to lift the tip of the tongue or by lifting it
with a spatula.

MESOPHARINGOSCOPY
4. Holding a spatula in your left hand, press the front 2/3 of the tongue downwards without touching it
root of the tongue. The spatula is inserted through the right corner of the mouth, the tongue is not pressed flat
spatula, and its end. When you touch the root of the tongue, an vomiting sensation immediately occurs.
movement. Determine the mobility and symmetry of the soft palate by asking
the patient pronounce the sound “a”. Normally, the soft palate is well mobile, the left and
the right sides are symmetrical.
5. Examine the mucous membrane of the soft palate, its uvula, anterior and posterior
palatal arches. Normally, the mucous membrane is smooth, pink, and the arches are contoured.
Examine the teeth and gums to identify pathological changes.
The size of the palatine tonsils is determined by mentally dividing them into three parts.
distance between the medial edge of the anterior palatine arch and the vertical
a line passing through the middle of the uvula and soft palate. The size of the tonsil,
protruding up to 1/3 of this distance is classified as I degree, protruding up to 2/3 - to II
degrees; protruding to the midline of the pharynx - to the III degree.

6. Examine the mucous membrane of the tonsils. Normally it is pink
moist, its surface is smooth, the mouths of the lacunae are closed, discharge in
there are none.
7. Determine the contents in the crypts of the tonsils. To do this, take two
spatula, in the right and left hands. Press down with one spatula
tongue, the other gently presses through the anterior arch onto the tonsil
in the area of ​​its upper third. When examining the right tonsil, the tongue
squeeze with a spatula in the right hand, and when examining the left tonsil with a spatula in the left hand. Normally, there is no content in crypts or it is
scanty, non-purulent in the form of minor epithelial plugs.
8. Examine the mucous membrane of the posterior pharyngeal wall. She's normal
pink, moist, smooth, on its surface rare, sized
up to 1 mm, lymphoid granules.

EPIPHARYNGOSCOPY (POSTERIOR RHINOSCOPY)

5 methods of blowing the auditory tube are performed sequentially. Opportunity
performing one or another method allows you to determine I, II, III, IV or V degrees
patency of the pipe. When performing an examination, one end of the otoscope is placed in
the external auditory canal of the subject, the second - the doctor. The doctor listens through an otoscope
the sound of air passing through the auditory tube.
The empty swallow test allows you to determine the patency of the auditory tube during
making a swallowing movement. When opening the lumen of the auditory tube, the doctor
through the otoscope hears a characteristic light noise or crackling sound.
Toynbee's method. This is also a swallowing movement, but performed by the subject with
closed mouth and nose. During the examination, if the tube is passable, the patient
feels a push in the ears, and the doctor hears a characteristic sound of air passing.
Valsalva method. The subject is asked to take a deep breath and then
increased expiration (inflating) with the mouth and nose tightly closed. Under pressure
exhaled air, the auditory tubes open and air forcefully enters
tympanic cavity, which is accompanied by a slight cracking sound that is felt
the person being examined, and the doctor listens to a characteristic noise through an otoscope. In case of violation

X-rays of both temporal bones are taken at once. Main
the prerequisite for traditional radiography of the temporal bones is

diagnostic errors.
Lateral plain radiography of the temporal bones, according to Schuller
,allows us to identify the structure of the mastoid process. On

Depending on the tasks facing the doctor, the volume
The research performed may vary. Information
about the state of hearing is necessary not only for diagnosis
ear diseases and resolving the issue of conservative and
surgical treatment, but also during professional selection,
selection of a hearing aid. It is very important
Hearing examination in children to identify early disorders
hearing

Hearing research using speech. After identifying complaints and
collecting anamnesis, performing a speech hearing test,
determine the perception of whispered and spoken speech.
The patient is placed at a distance of 6 m from the doctor; test ear
should be directed towards the doctor, and the opposite
the assistant closes, pressing the tragus tightly to the hole
external auditory canal with the second finger, while the third finger slightly
rubs II, which creates a rustling sound that drowns out that ear,
excluding rehearsal

The subject is explained that he must repeat loudly
heard words. To eliminate lip reading, the patient should not
look towards the doctor. Whisper, using the air remaining in
lungs after unforced exhalation, the doctor pronounces words with
low sounds (number, hole, sea, tree, grass, window, etc.), then
words with high sounds are treble (thicket, already, cabbage soup, hare, etc.).
Patients with damage to the sound-conducting apparatus (conductive
hearing loss) they hear low sounds worse. On the contrary, in case of violation
sound perception (sensorineural hearing loss) hearing deteriorates
high sounds.
If the subject cannot hear from a distance of 6 m, the doctor shortens
a distance of 1 m and again examines the hearing. This procedure is repeated until
until the subject hears all spoken words.
Normally, when studying the perception of whispered speech, a person hears
low sounds from a distance of at least 6 m, and high sounds - 20 m.
The study of spoken speech is carried out according to the same rules.
The results of the study are recorded in a hearing passport.

Tuning fork testing is the next step in hearing assessment.
Air conduction study. Tuning forks are used for this
S128 and S2048. The study begins with a low-frequency tuning fork
Holding the tuning fork by the stem with two fingers,
the impact of the jaws on the tenor of the palms causes it to oscillate. Tuning fork S2048
set into vibration by abruptly squeezing the jaws with two fingers
or with the flick of a fingernail.
A sounding tuning fork is brought to the external auditory canal of the subject
at a distance of 0.5 cm and hold it so that the jaws make
vibrations in the plane of the axis of the auditory canal. Starting the countdown from
moment of impact of the tuning fork, a stopwatch measures the time during
which the patient hears its sound. After the subject stops
hear a sound, the tuning fork is moved away from the ear and brought closer again, without exciting
it again. As a rule, after such a distance from the ear of the tuning fork, the patient
He hears the sound for a few more seconds. The final time is marked according to
to the last answer. The study is carried out similarly with a C2048 tuning fork,
determine the duration of perception of its sound through the air.

The sounding tuning fork C128 is placed perpendicularly with the leg on the platform

tuning fork.
If sound conduction is impaired (conductive hearing loss), it worsens
perception through the air of a low-sounding tuning fork C128; at
In bone conduction studies, the sound is heard longer.
Impaired perception through the air of a high tuning fork C2048
accompanied mainly by damage to the sound-perceiving
device (sensorineural hearing loss). Decreases proportionally
and the duration of the sound of C2048 through air and bone, although the ratio
These indicators remain, as normal, 2:1.

Qualitative tuning fork tests are carried out with the aim of
differential express diagnosis of lesions
sound-conducting or sound-receiving sections of the auditory
analyzer. For this purpose, experiments are carried out by Rinne, Weber, Jelle,
Federice, when performing them they use a C128 tuning fork.
Rinne's experiment consists of comparing the duration of aerial and
bone conduction. The sounding tuning fork C128 is placed with its stem against
site of the mastoid process. After the cessation of sound perception
along the bone, a tuning fork, without exciting it, is brought to the external auditory
aisle. If the subject continues to hear sound through the air
tuning fork, Rinne’s experience is regarded as positive (R+). In that
if the patient stops sounding the tuning fork
mastoid process does not hear it and at the external auditory canal,
Rinne's experience is negative (R-).

With Rinne's positive experiment, air conduction of sound in
1.5-2 times higher than bone, when negative - vice versa.
Rinne's positive experience is observed normally, negative
- in case of damage to the sound-conducting apparatus, i.e. at
conductive hearing loss.
If the sound-receiving apparatus is damaged (i.e.
sensorineural hearing loss) conduction of sounds through the air, as in
normally, prevails over bone conduction. However, at the same time
duration of perception of the sounding tuning fork as if through air,
and bone conductivity is less than normal, therefore
Rinne's experience remains positive.

Weber's experiment (W). It can be used to evaluate the lateralization of sound.
A sounding tuning fork C128 is placed at the crown of the subject to
the leg was in the middle of the head (see Fig. 1.15 a). Branches
The tuning fork must oscillate in the frontal plane. IN
Normally, the subject hears the sound of a tuning fork in the middle of the head or
equally in both ears (normal<- W ->). With unilateral
damage to the sound-conducting apparatus, the sound is lateralized in
affected ear (for example, left W ->), with unilateral lesion
sound-receiving apparatus (for example, on the left) sound
lateralizes into the healthy ear (in this case, to the right<При двусторонней кондуктивной тугоухости звук будет латерализоваться
to the side of the worse hearing ear, with bilateral neurosensory - in
side of the better hearing ear.

Jelle's experiment (G). The method makes it possible to detect sound conduction disorders associated with
immobility of the stapes in the window of the vestibule. This type of pathology is observed in
particularly in otosclerosis.
A sounding tuning fork is placed on the crown of the head and at the same time a pneumatic
a funnel is used to condense the air in the external auditory canal (see Fig. 1.15 b). At the moment
compression, a subject with normal hearing will feel a decrease in perception,
which is associated with deterioration in the mobility of the sound-conducting system due to
pressing the stapes into the niche of the window of the vestibule - Jelle’s experience is positive (G+).
With the stapes immobilized, there is no change in perception at the moment of condensation
air in the external auditory canal will not occur - Jelle’s experience is negative
(G-).
Federici experiment (F). It consists of comparing the duration of perception of the sound
tuning fork C128 from the mastoid process and tragus during obturation of the external
ear canal. After the sound stops on the mastoid process, the tuning fork
placed the leg on the tragus.
In normal conditions and in cases of impaired sound perception, Federici’s experience is positive, i.e.
the sound of a tuning fork from the tragus is perceived longer, and if
sound conduction - negative (F-).
Thus, Federici's experience, along with other tests, allows
differentiate between conductive and sensorineural hearing loss.

The use of electroacoustic equipment allows dosing
the strength of the sound stimulus in generally accepted units - decibels
(dB), conduct a hearing test in patients with severe
hearing loss, use diagnostic tests.
An audiometer is an electrical sound generator that allows
deliver relatively pure sounds (tones) both through air and through
bone. A clinical audiometer examines hearing thresholds in the range
from 125 to 8000 Hz. Nowadays audiometers have appeared,
allowing you to study hearing in an expanded frequency range - up to 18
000-20,000 Hz. With their help, audiometry is performed in advanced
frequency range up to 20,000 Hz over the air. Through transformation
attenuator, the supplied audio signal can be amplified up to 100-120
dB when studying air and up to 60 dB when studying bone
conductivity. The volume is usually adjusted in steps of 5 dB, in
on some audiometers - in more fractional steps, starting from 1 dB.

From a psychophysiological point of view, various
audiometric methods are divided into subjective and objective.
Subjective audiometric techniques are the most widely used
application in clinical practice. They are based on
subjective sensations of the patient and on the conscious, depending on his
will, response. Objective or reflex audiometry
based on reflex unconditional and conditioned responses
reactions of the subject that occur in the body during sound
influence and independent of his will.
Taking into account what stimulus is used in the study
sound analyzer, there are such subjective methods as
tone threshold and suprathreshold audiometry, research method
auditory sensitivity to ultrasound, speech audiometry.

Pure-tone audiometry can be threshold or suprathreshold.
Pure tone threshold audiometry is performed to determine thresholds
perception of sounds of different frequencies during air and bone conduction.
Using air and bone telephones, the threshold is determined
sensitivity of the hearing organ to the perception of sounds of different frequencies. Results
research is entered on a special form-grid, called
"audiogram".
An audiogram is a graphical representation of hearing threshold. Audiometer
designed to show hearing loss in decibels compared to
the norm. Normal hearing thresholds for sounds of all frequencies, both airborne and
bone conduction is marked with a zero line. Thus, tonal
A threshold audiogram primarily makes it possible to determine hearing acuity.
According to the nature of the threshold curves of air and bone conduction and their
relationships, one can also obtain a qualitative characteristic of the patient’s hearing, i.e.
determine whether there is a violation of sound conduction, sound perception or
mixed (combined) lesion.

If sound conduction is impaired, the audiogram shows an increase in
air conduction hearing thresholds mainly in the range
low and medium frequencies and, to a lesser extent, high frequencies. Auditory thresholds according to
bone conductivity remain close to normal, between threshold
curves of bone and air conduction there is a significant
called air-bone gap (cochlear reserve).
If sound perception is impaired, air and bone conduction
suffer to the same extent, the air-bone gap is almost
absent. In the initial stages, perception is predominantly affected
high tones, and in the future this is a violation
appears at all frequencies; there are breaks in the threshold curves, i.e.
lack of perception of certain frequencies
Mixed, or combined, hearing loss is characterized by the presence of
audiogram showing signs of impaired sound conduction and sound perception, but
There is a bone-air gap between them.

Audiogram for impairment
sound conduction:
a - conductive form of hearing loss;
b - sensorineural form of hearing loss;
c - mixed form of hearing loss

Pure tone suprathreshold audiometry. Designed to identify
phenomenon of accelerated increase in volume (FUNG - in domestic
literature, the phenomenon of recruitment, recruitment phenomenon - in
foreign literature).
The presence of this phenomenon usually indicates damage to receptors
cells of the spiral organ, i.e. about intracochlear (cochlear) lesion
auditory analyzer.
A patient with decreased hearing acuity develops increased
sensitivity to loud (suprathreshold) sounds. He notes unpleasant
sensations in the sore ear if someone speaks loudly or harshly to it
strengthen the voice. The presence of FUNG can be suspected by clinical
examination. This is evidenced by the patient’s complaints of intolerance
loud sounds, especially with a sore ear, the presence of dissociation between
perception of whispered and spoken speech. Whispering speech of the patient completely
does not perceive or perceives at the sink, while spoken
hears at a distance of more than 2 m. When carrying out Weber's experiment,
change or sudden disappearance of sound lateralization, with
tuning fork examination, audibility suddenly stops
tuning fork while slowly moving it away from the sore ear.

Methods of suprathreshold audiometry (there are more than 30 of them) allow direct or
indirectly detect FUNG. The most common among them
are classical methods: Luscher - definition
differential threshold for perception of sound intensity,
volume leveling according to Fowler (for unilateral hearing loss),
Small Increment Intensity Index (SMI, often referred to as
as SISI test). Normal differential sound intensity threshold
is equal to 0.8-1 dB, the presence of FUNG is indicated by its decrease below
0.7 dB.
Study of auditory sensitivity to ultrasound. Normal
a person perceives ultrasound during bone conduction in the range
frequencies up to 20 kHz and more. If hearing loss is not associated with a lesion
cochlea (neurinoma of the VIII cranial nerve, brain tumors, etc.),
ultrasound perception remains the same as normal. At
In case of damage to the cochlea, the threshold for the perception of ultrasound increases.

Speech audiometry, unlike tonal audiometry, allows you to determine
social suitability of hearing in a given patient. The method is
especially valuable in the diagnosis of central hearing lesions.
Speech audiometry is based on determining intelligibility thresholds
speech. Legibility is understood as a value defined as
ratio of the number of correctly understood words to the total number
listened to, express it as a percentage. So, if out of 10
The patient correctly understood the words presented for listening
all 10, it will be 100% legible if you parse 8, 5 or
2 words, this will be 80, 50 or 20% intelligibility respectively.
The study is carried out in a soundproofed room. Results
studies are recorded on special forms in the form of curves
speech intelligibility, while the intensity is marked on the x-axis
speech, and on the y-axis is the percentage of correct answers. Curves
intelligibility is different for various forms of hearing loss, which has
differential diagnostic value.

Objective audiometry. Objective methods of hearing research
based on unconditioned and conditioned reflexes. Such research has
significance for assessing the state of hearing in cases of damage to the central parts
sound analyzer, during labor and forensic testing
examination. With a strong sudden sound, unconditioned reflexes
are reactions in the form of pupil dilation (cochlear-pupillary reflex,
or auropupillar), closing the eyelids (auropalpebral, blinking
reflex).
Most often, galvanic skin testing is used for objective audiometry.
and vascular reactions. The galvanic skin reflex is expressed in
change in potential difference between two areas of skin under
influenced, in particular, by sound stimulation. Vascular reaction
consists in changing vascular tone in response to sound stimulation, which
recorded, for example, using plethysmography.
In young children, the reaction most often recorded is during play.
audiometry, combining sound stimulation with the appearance of a picture in
the moment the child presses the button. Loud sounds at first
are replaced by quieter ones and auditory thresholds are determined.

The most modern method of objective hearing testing is
audiometry with recording of auditory evoked potentials (AEP). The method is based
on registration of sounds evoked in the cerebral cortex
potentials on the electroencephalogram (EEG). It can be used in children
infancy and young age, in mentally handicapped persons and persons with normal
psyche. Since EEG responses to sound signals (usually short - up to 1 ms,
called audible clicks) are very small - less than 1 µV, to register them
use averaging using a computer.
Recording of short-latency auditory evoked responses is more widely used.
potentials (KSVP), giving an idea of ​​the state of individual formations
subcortical pathway of the auditory analyzer (vestibular-cochlear nerve, cochlear
nuclei, olives, lateral lemniscus, quadrigeminal tuberosities). But CVEPs do not provide any complete picture of the response to a stimulus of a certain frequency, since
the stimulus itself should be short. In this regard, more informative
long-latency auditory evoked potentials (LAEPs). They register
responses of the cerebral cortex to relatively long-term, i.e. having a certain
frequency of sound signals and they can be used to remove auditory
sensitivity at different frequencies. This is especially important in pediatric practice, when
Conventional audiometry, based on the patient's conscious responses, is not applicable.

Impedance audiometry is one of the methods of objective assessment
hearing based on acoustic impedance measurement
sound-conducting apparatus. In clinical practice they use
two types of acoustic impedance measurements - tympanometry and
acoustic reflexometry.
Tympanometry consists of recording acoustic
resistance that a sound wave encounters when
propagation through the acoustic system of outdoor, middle and
inner ear, when air pressure changes in the outer ear
ear canal (usually from +200 to -400 mm water column). Curve,
reflecting the dependence of the resistance of the eardrum
from pressure, called a tympanogram. Various types
tympanometric curves reflect normal or
pathological condition of the middle ear.

Acoustic reflexometry is based on recording changes
compliance of the sound-conducting system, occurring when
contraction of the stapedius muscle. Triggered by sound stimulus
nerve impulses travel along the auditory tract to the superior olive
nuclei, where they switch to the motor nucleus of the facial nerve and go to
stapedius muscle. Muscle contraction occurs on both sides. IN
a sensor is inserted into the external auditory canal, which responds to
change in pressure (volume). In response to sound stimulation
an impulse is generated, passing through the above-described reflex
arch, as a result of which the stapedius muscle contracts and comes into
the eardrum moves, the pressure (volume) changes
external auditory canal, which is what the sensor records. Normal threshold
the acoustic reflex of the stapes is about 80 dB above
individual sensitivity threshold. For neurosensory
hearing loss accompanied by FUNG, reflex thresholds are significantly
are decreasing. For conductive hearing loss, pathology of the nuclei or brainstem
facial nerve acoustic reflex of the stapes is absent on the side
defeats. For differential diagnosis of retrolabyrinthine
damage to the auditory tract, the decay test is of great importance
acoustic reflex.

Types of tympanometric curves (according to Serger):
a - normal;
b - with exudative otitis media;
c - when the chain of auditory ossicles breaks

The examination of the patient always begins with clarification of complaints and
history of life and illness. The most common complaints
for dizziness, balance disorder, manifested
disturbance of gait and coordination, nausea, vomiting,
fainting, sweating, change in skin color
covers, etc. These complaints may be persistent or
appear periodically, be fleeting, or
last for several hours or days. They may occur
spontaneously, for no apparent reason, or under the influence
specific environmental factors and the body: in transport,
surrounded by moving objects, when overtired,
motor load, certain head position, etc.

Vestibulometry includes identifying spontaneous symptoms,
conducting and evaluating vestibular tests, analysis and generalization
received data. To spontaneous vestibular symptoms
include spontaneous nystagmus, changes in muscle tone of the limbs,
gait disturbance.
Spontaneous nystagmus. The patient is examined in a sitting position or in
supine position, with the subject watching the finger
doctor, at a distance of 60 cm from the eyes; finger moves
consistently in horizontal, vertical and diagonal
planes. Eye abduction should not exceed 40-45°, since
overstrain of the eye muscles may be accompanied by twitching
eyeballs. When observing nystagmus, it is advisable to use
High magnification glasses (+20 dioptres) to eliminate interference
fixation of gaze. Otorhinolaryngologists use for this purpose
special Frenzel or Bartels glasses; even more clearly
spontaneous nystagmus is detected by electronystagmography.

When examining the patient in a supine position with the head and
the body is given different positions, while in some
patients observe the appearance of nystagmus, designated as
positional nystagmus (nystagmus of position). Positional nystagmus
may have a central genesis, in some cases it is associated with
dysfunction of the otolith receptors, from which the
tiny particles and enter the ampoules of the semicircular canals with
pathological impulses from cervical receptors.
In the clinic, nystagmus is characterized by plane (horizontal,
sagittal, rotatory), in direction (right, left, up,
down), by strength (I, II or III degree), by the speed of oscillatory cycles
(live, sluggish), amplitude (small-, medium-, or large-scale),
by rhythm (rhythmic or disrhythmic), by duration (in seconds).

In terms of strength, nystagmus is considered degree I if it occurs only when
looking towards the fast component; II degree - not visible
only towards the fast component, but also directly; finally,
III degree nystagmus is observed not only in the first two
eye positions, but also when looking towards the slow
component. Vestibular nystagmus usually does not change its
directions, i.e. in any eye position its fast component
directed in the same direction. About extralabyrinthine
the (central) origin of nystagmus is evidenced by its
undulating character, when it is impossible to distinguish fast and
slow phase. Vertical, diagonal,
multidirectional (changing direction when looking at
different sides), converging, monocular,
asymmetrical (not the same for both eyes) nystagmus
characteristic of disorders of central origin.

Tonic reactions of hand deviation. They are examined at
performing index tests (finger-nose, finger-finger), Fischer-Wodak test.
Index samples. When performing a finger-nose test
the subject spreads his arms to the sides and first with open, and
then, with his eyes closed, tries to touch with his index fingers
fingers of one and then the other hand to the tip of your nose. At
in the normal state of the vestibular analyzer it is without
difficulty completing the task. Irritation of one of
labyrinths leads to missing with both hands in
the opposite side (towards the slow component
nystagmus). When the lesion is localized in the posterior cranial fossa
(for example, with cerebellar pathology) the patient misses
with one hand (on the side of the disease) towards the “sick” side.

During the finger-finger test, the patient alternately uses his right and left hand
should hit the doctor's index finger with your index finger,
located in front of him at arm's length. Try
performed first with open, then with closed eyes. Normal
the subject confidently hits the doctor's finger with both hands, as if with
with eyes open and with eyes closed.
Fischer-Wodak test. It is performed by the subject sitting with the
eyes and with arms extended forward. Index fingers extended
the rest are clenched into a fist. The doctor positions his index fingers
opposite the patient's index fingers and in the immediate
proximity to them and observes the deviation of the subject’s hands. U
in a healthy person there is no deviation of the hands; in case of damage
maze, both hands are deviated towards the slow component
nystagmus (i.e. towards the labyrinth, the impulse from which
reduced).

Study of stability in the Romberg pose. The subject is standing
bringing your feet together so that their toes and heels touch, hands
extended forward at chest level, fingers spread, eyes
closed. In this position, the patient should be secured,
so that he doesn't fall. If the function of the labyrinth is impaired, the patient
will deviate in the direction opposite to nystagmus. Should
take into account that even with cerebellar pathology there may be a deviation
torso in the direction of the lesion, so the study is in the pose
Romberg is supplemented by turning the subject’s head to the right and
to the left. When the labyrinth is damaged, these turns are accompanied by
change in the direction of fall, with cerebellar damage
the direction of deviation remains unchanged and does not depend on
turning the head.

Gait in a straight line and flank:
1)
2)
when examining the patient's gait in a straight line with his eyes closed
takes five steps forward in a straight line and then, without turning, 5 steps
back. If the function of the vestibular analyzer is impaired, the patient
deviates from a straight line in the direction opposite to nystagmus, with
cerebellar disorders - in the direction of the lesion;
flank gait is examined as follows. The subject leaves
right foot to the right, then puts the left one and takes 5 steps in this way, and
then similarly takes 5 steps to the left. In case of violation
vestibular function, the subject performs the flank gait well in
both sides, if the function of the cerebellum is impaired, it cannot perform it in
side of the affected cerebellar lobe.
Also for the differential diagnosis of cerebellar and vestibular
lesions, a test for adiadochokinesis is performed. The subject performs it with
with eyes closed, both arms extended forward, makes a quick change
pronation and supination. Adiadochokinesis - a sharp lag of the hand on the “sick”
side with impaired cerebellar function.

Vestibular tests allow us to determine not only the presence
dysfunction of the analyzer, but also to provide high-quality and
quantitative characteristics of their features. The essence of these samples
consists of stimulating vestibular receptors with the help of
adequate or inadequate dosage effects.
Thus, for ampullary receptors an adequate stimulus is
angular accelerations, dosed rotational acceleration is based on this
swivel chair test. An inadequate irritant for those
same receptors is the effect of dosed caloric
stimulus when infusion of different water into the external auditory canal
temperature leads to cooling or heating of liquid media
inner ear and this causes movement according to the law of convection
endolymph in the horizontal semicircular canal located
closest to the middle ear. Also an inadequate irritant for
vestibular receptors are exposed to galvanic current.
For otolith receptors, an adequate stimulus is
linear acceleration in horizontal and vertical planes
when performing a test on a four-bar swing.

Rotational test. The subject is seated in a Barani chair like this
so that his back fits snugly against the back of the chair, his legs
were placed on a stand, and their hands were on the armrests. Patient's head
leans forward and down 30°, eyes should be closed. Rotation
produced evenly at a speed of 1/2 revolution (or 180°) per second, in total
10 revolutions in 20 s. At the beginning of rotation, the human body experiences
positive acceleration, at the end - negative. When rotating
clockwise after stopping the endolymph flow in horizontal
the semicircular canals will continue to the right; hence slow
the component of nystagmus will also be to the right, and the direction of nystagmus (fast
component) - left. When moving to the right when the chair stops at
in the right ear, the movement of the endolymph will be ampulofugal, i.e. from the ampoule, and in
left - ampulopetal. Therefore, post-rotational nystagmus and
other vestibular reactions (sensory and autonomic) will
are caused by irritation of the left labyrinth, and the post-rotation reaction
from the right ear - observed when rotating counterclockwise, i.e.
to the left. After the chair stops, the countdown begins. Subject
fixes his gaze on the doctor’s finger, while determining the degree of nystagmus,
then determine the nature of the amplitude and liveliness of the nystagmus, its
duration when the eyes are positioned towards the fast component.

If the functional state of the anterior receptors is studied
(frontal) semicircular canals, then the subject sits in
Barani chair with the head tilted back 60°, if
the function of the posterior (sagittal) canals, head is studied
tilts 90° to the opposite shoulder.
Normal duration of nystagmus when examining lateral
(horizontal) semicircular canals is 25-35 s, with
study of the posterior and anterior canals - 10-15 s. Character
nystagmus when irritating the lateral canals is horizontal, the anterior ones are rotatory, the posterior ones are vertical;
in amplitude it is small or medium in scope, grades I-II,
lively, quickly fading.

Caloric test. During this test, a weaker level is achieved than with
rotation, artificial irritation of the labyrinth, mainly receptors
lateral semicircular canal. An important advantage of the caloric test
is the ability to irritate isolated ampullary receptors of one
sides.
Before performing an aqueous caloric test, make sure that there is no
dry perforation in the eardrum of the ear being examined, since
water into the tympanic cavity can cause exacerbation of chronic
inflammatory process. In this case, an aerial
calorization.
The caloric test is performed as follows. The doctor draws Zhane into the syringe
100 ml of water at a temperature of 20 ° C (with a thermal caloric test, the temperature
water is +42 °C). The subject sits with his head tilted back 60°; at the same time
The lateral semicircular canal is located vertically. Pour into external
ear canal 100 ml of water for 10 s, directing the stream of water along its posterior superior
wall Determine the time from the end of the infusion of water into the ear until the appearance of
nystagmus is a latent period, normally equal to 25-30 s, then it is recorded
The duration of the nystagmus reaction is normally 50-70 s. Characteristics
nystagmus after calorization is given according to the same parameters as after rotation
samples. When exposed to cold, nystagmus (its fast component) is directed towards
the side opposite to the ear being tested, during thermal calorization - to the side
irritated ear.

Methodology
caloric test

Pressor (pneumatic, fistula) test. It is carried out for
identifying a fistula in the area of ​​the labyrinthine wall (most often in
area of ​​the ampulla of the lateral semicircular canal) in patients
chronic purulent otitis media. The sample is produced
thickening and rarefaction of air in the external auditory canal,
either by applying pressure to the tragus or using a rubber bulb.
If, in response to air thickening, nystagmus and other
vestibular reactions, then the pressor test is assessed as
positive. This indicates the presence of a fistula. Should
take into account, however, that a negative test does not allow complete
confidently deny the presence of a fistula. With extensive
perforations in the eardrum can be made
direct pressure with a probe with cotton wool wrapped around it
to areas of the labyrinthine wall that are suspicious for a fistula.

Study of the function of the otolithic apparatus. It is carried out mainly
in professional selection, in clinical practice, direct methods
and indirect otolitometry are not widely used. WITH
taking into account the interdependence and mutual influence of the otolith and cupular
departments of the analyzer V.I. Vojacek proposed a technique he called
"double experiment with rotation" and known in the literature as "Otolith
Vojacek reaction.
Otolithic reaction (OR). The subject sits in a Barani chair and
tilts the head along with the body 90° forward and down. In this
position it is rotated 5 times for 10 s, then the chair
stop and wait 5 s, after which they are asked to open their eyes and
straighten up. At this moment a reaction occurs in the form of a tilt
torso and head to the side. Functional state of the otolith
the apparatus is assessed by degrees of deviation of the head and torso from
midline towards the last rotation. Also taken into account
severity of vegetative reactions.

Thus, a deviation of an angle from 0 to 5° is assessed as degree I
reactions (weak); deviation of 5-30° - II degree (medium strength).
Finally, deviation by an angle of more than 30° is grade III (strong), when
the subject loses his balance and falls. Reflex angle
the slope in this reaction depends on the degree of influence of the otolith
irritation when straightening the body on the function of the anterior
semicircular canals. In addition to the somatic reaction, this
experience takes into account vegetative reactions, which can also be
three degrees: I degree - paleness of the face, change in pulse; II
degree (moderate) - cold sweat, nausea; III degree - change
cardiac and respiratory activity, vomiting, fainting. Experience
double rotation is widely used during examination
healthy people for the purpose of professional selection.

When selecting aviation and astronautics for research
sensitivity of the subject to the cumulation of the vestibular
irritation, the proposed
K.L. Khilov back in 1933, a technique for motion sickness
four-bar (two-bar) swing. Swing area
oscillates not like an ordinary swing - in an arc, but remains
constantly parallel to the floor. The subject is on
swing platform lying on your back or side, using
electrooculography techniques record tonic movements
eye. Modification of the method using small
dosed according to the amplitude of swings and registration
compensatory eye movements is called “direct
otolitometry".

Stabilometry. Among the objective methods for assessing static
equilibrium method is becoming increasingly widespread
stabilometry, or posturography (posture - pose). The method is based
on recording oscillations of the center of pressure (gravity) of the body
patient installed on a special stabilometric
platform. Body vibrations are recorded separately in
sagittal and frontal planes, calculate a whole series
indicators that objectively reflect the functional state
equilibrium systems. The results are processed and summarized with
using a computer. Combined with a set of functional
sample computer stabilometry is
highly sensitive method and is used to detect
vestibular disorders at the earliest stage, when
subjectively they do not yet manifest themselves (Luchikhin L.A., 1997).

Stabilometry finds application in differential
diagnosis of diseases accompanied by the disorder
balance. For example, a functional test with rotation
head (Palchun V.T., Luchikhin L.A., 1990) allows for early
stages to differentiate disorders caused by
damage to the inner ear or vertebrobasilar
insufficiency. The method makes it possible to control
dynamics of the development of the pathological process in the disorder
balance functions, objectively assess the results of treatment.
