Study of the function of the auditory tube

Violation of the ventilation function of the auditory tube is divided into 4 degrees depending on the performance of the samples.

1. Sample with an empty sip.

2. Toynbee test. The test subject swallows with a closed nasal cavity (the wings of the nose are pressed with fingers to the septum)

3. Test Valsalve. When the nasal cavity is closed, the air pressure in the nose is increased (straining), as when blowing your nose or blowing your ears in an airplane.

4. Sample Politzer. The olive bottle is introduced on the eve of one half of the nose, and the opposite wing of the nose is pressed against the septum and tightness is achieved. During the patient’s pronunciation of the last syllable of the word “pa-pa-go”, the balloon is compressed and air from the nose, nasopharynx enters the tympanic cavity through the auditory tube, which is necessarily controlled by the doctor using the Lucy otoscope, since the subjective responses of patients do not always correspond to objective data ( Fig. 1.4.1). The otoscope is a rubber tube with olives at the ends that are inserted into the ear of the doctor and patient. With a positive result of blowing the ear, the doctor feels the cotton in his ear. The otoscope must be used when conducting all samples.

Fig. 1.4.1

If all tests are performed with a positive result, then the ventilation function of the auditory tube is considered I degree, and if all samples are negative, then IV degree, etc. (Table 1.4.1)



Table 1.4.1

Ear ventilation function



Conclusion: ventilation function I / IV degree.



A study of the ventilation function of the auditory tube in the clinic is also carried out using special otomanometers Voyachek, Gerasimov, Svetlakov, Ipatov piezomanometer, by impedance measurement.
In fig. 1.4.2. The technique of ear manometry is shown by the Voyachek omanometer.

It is important to note that the study of the ventilation function of the auditory tube by any of these methods is carried out at ordinary atmospheric pressure. During the professional selection and examination of the flight crew, crew, divers, etc., not only ventilation, but also baroaccommodation ear function is studied. For this, the tolerance of atmospheric pressure drops is determined in the pressure chamber. With increasing external pressure on the human body, including the soft tissues of the neck, it is difficult to open the auditory tube with muscles that raise and tension the soft palate. The ability to baroaccommodate a person, that is, barofunction of the ear, depends on the strength of these muscles and the ability to timely equalize pressure in the tympanic cavity. With a decrease in external pressure, it is easier for air to spontaneously exit the tympanic cavity, but inflammation of the mucous membrane of the auditory tube violates both its ventilation and baroaccomodative functions.

In order to clarify the drainage function of the auditory tube, the clinic uses the methods of tragal injection of medicinal substances and contrast radiography.

Study of the function of the auditory tube

  1. Methods of researching the function of the auditory tube
    Assessment of patency of the auditory tube during examination of patients with ear pathology is a mandatory study, since dysfunction of the latter plays a significant role in the occurrence and course of many ear diseases. To determine the patency of the auditory tube (barofunction of the ears), the following tests are used: • regular sip; • swallowing with a pinched nose (Toynbee test); •
  2. The study of the functions of the auditory analyzer
    Speech and word of mouth - whisper and colloquial speech. The examinee is placed at a distance of 6 m from the doctor so that the test ear is turned in his direction, and the nurse closes the opposite ear, tightly pressing the tragus to the opening of the ear canal and with your finger, while the III finger slightly rubs against II, resulting in the formation of rustling sound
  3. Assessment of the functional state of the auditory tube
    The function of the auditory tube can be estimated based on tympanometry data. The main indicator in this case will be the level of intra-drum pressure (IWB). As already noted, the peak pressure value corresponds to the level of intra-drum pressure, which directly depends on the effectiveness of the ventilation function of the auditory tube. With lesions of the auditory tube, the pressure of the peak (and IAP) is shifted to the side

  9. Auditory Disorders
    Hearing disorders - deafness, hearing loss, auditory agnosia - are associated with damage to the auditory analyzer, which consists of a peripheral receptor - the Corti organ, which is located in the cochlea of ​​the inner ear, the auditory nerve that extends from it, the auditory tract is continued in the brain, and the cortical auditory center in the cortex of the temporal lobe. Hearing impairment in childhood more often
  10. Sound conducting and sound receiving functions of the auditory analyzer
    The various parts of the auditory analyzer, or organ of hearing, perform two functions of a different nature: 1) sound conduction, that is, delivery of sound vibrations to the receptor (the ends of the auditory nerve); 2) sound perception, i.e. the reaction of nerve tissue to sound irritation. The sound conduction function consists in the transfer of the outer, middle and partly inner ear by the constituent elements
  11. The main stages in the development of auditory function in a child
    The human auditory analyzer begins to function from the moment of its birth. Under the influence of sounds of sufficient volume in newborns, one can observe responses that proceed as unconditioned reflexes and manifest themselves in the form of changes in breathing and pulse, delayed sucking movements, etc. At the end of the first and beginning of the second month of life, the child already has conditioned reflexes to

  13. Diseases of the auditory nerve, pathways and auditory centers in the brain
    Lesions of the conduction department of the auditory analyzer can occur on any part of it. The most common are diseases of the first neuron, united in a group called the auditory nerve neuritis. This name is somewhat arbitrary, since this group includes not only diseases of the auditory nerve trunk, but also lesions of nerve cells that make up
  14. The study of the functions of phagocytes
    A. Monocytes and macrophages. Using laboratory methods, the following functions of monocytes and macrophages can be evaluated: antigen presentation to T-lymphocytes, antibody-dependent cellular cytotoxicity, antitumor cytotoxicity, chemotaxis, phagocytosis and bactericidal activity. In addition, cytokine production by activated macrophages can be investigated. Study of monocyte function and
  15. RESEARCH OF HIGHER CORTIC FUNCTIONS
    Research methods for higher cortical functions are described in detail in the corresponding courses (psychology, psychopathology of childhood). We will only indicate that in the study of neurological status, gnosis, praxis, speech, memory, thinking are examined. The necessary information about the mental state of children is obtained during observation of their facial expressions, manner of play, behavior in a new environment, etc.
