Tympanometry is an objective test that evaluates the mobility of the middle ear and eardrum by applying controlled air pressure to the external ear canal. This measurement is performed using a special probe placed in the ear. The mobility data obtained provides important information about the functional status of the middle ear structures. The test can be easily applied to individuals of all ages, including infants. The only important prerequisite for tympanometry is the absence of a perforation (hole) in the eardrum.
