Tympanometry

Tympanometry is a method for objectively studying the functions of the structure of the middle ear, making it possible to assess the degree of mobility of the eardrum, the function of the auditory ossicles (hammer, incus and stapes), as well as the function of the auditory tube, carried out by creating various air vibrations in the external auditory canal.

The procedure takes about 15-30 minutes and provides accurate information about the condition of the middle ear structure. The procedure is absolutely painless and therefore does not require anesthesia. Sometimes discomfort may occur during the examination.

INDICATIONS FOR TYMPANOMETRY

  • persistent hearing loss;
  • noise in ears;
  • pathological discharge from the ear canal;
  • ear canal injuries;
  • pain in the ear or in the temporal region of the head;
  • previously suffered inflammatory processes;
  • recurrent otitis media, rhinitis, sinusitis;
  • adenoiditis;
  • suspicion of otosclerosis;
  • acute otitis media, including exudative;
  • suspected tumor in the middle ear.

CONTRAINDICATIONS TO TYMPANOMETRY

  • acute inflammatory diseases of the ear (meningitis, purulent otitis media);
  • fresh injury to the auditory analyzer;
  • violation of the integrity of the eardrum (in this case, the study is technically possible, but not informative).

HOW IS TYMPANOMETRY DONE?

Each ear is examined separately. A device is used that creates pressure in the external auditory canal. Using a rubber probe that seals the outer ear and generates a sound wave, the device pumps up pressure in the external auditory canal from -400 to +400 mmH2O. Art.

In response to this impact, the eardrum begins to vibrate. The sensor records these vibrations, and the device displays a graph of the movement of the eardrum, depending on the pressure in the ear canal. This curve is called a tympanogram. The doctor evaluates her and makes recommendations for treatment.

WHO CAN HAVE TYMPANOMETRY

This diagnostic procedure can be performed on all patients without age restrictions, as well as children of any age, including newborns.
