Tympanometry is a technique used to look at the function of the middle ear. It is NOT a hearing test. It is a test used together with otoscopy and audiometry and is useful in helping to determine how the middle ear is functioning.

Tympanograms are classified into types according to the shape of the tympanometric trace (“peak”), which is dependent upon the middle ear pressure, and the middle ear compliance

Type A- Represents a Normal Middle ear function.  Shows normal Mobility and Conduction. It does not get affected in Sensorineural Hearing Loss​​​​​​​

Tybe B-  Represents a restricted tympanic membrane mobility as seen in Otitis Media

Type C : Represents Significant Negative Pressure in Middle Ear Cavity as seen in Eustachian Tube Blockage.
