What is "tympanometry"

n. An examination to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) and the ossicle chain by creating variations of air pressure in the ear canal.

Tympanometry is an examination used to test the condition of the middle ear and mobility of the eardrum ( tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal.

Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. The test should not be used to assess the sensitivity of hearing and the results of this test should always be viewed in conjunction with pure tone audiometry.

Tympanometry is a valuable component of the audiometric evaluation. In evaluating hearing loss, tympanometry permits a distinction between sensorineural and conductive hearing loss, when evaluation is not apparent via Weber and Rinne testing. Furthermore, in a primary care setting, tympanometry can be helpful in making the diagnosis of otitis media by demonstrating the presence of a middle ear effusion.
