Description of the study

Adequate cooperation with the instructor is required for the test. The examinee has the tympanometer probe placed in the external ear canal, then the initial pressure in the eardrum cavity is tested. The examinee while plugging the nose and swallowing saliva induces negative pressure in the tympanic cavity, then the ear pressure is measured again. The examinee exhales while closing the mouth and plugging the nose, this creates positive pressure in the ear. A final measurement of the pressure in the eardrum cavity is then taken.
The test takes a few minutes, the patient may feel slight discomfort in the ear.


  • Assessment of the patency of the auditory trumpet.
