Tympanometry
Tympanometry is a test used in the diagnosis of ear diseases. With this test, the air pressure in the middle ear, the mobility of the eardrum, and the function of the ear ossicles are evaluated. It is mainly used to detect the presence of fluid in the middle ear, perforation (hole) in the eardrum, hardening of the hearing bones or functional problems in the ear canal.
How is it done?
During tympanometry, a small probe is inserted into the ear canal. Through this probe, the air pressure is changed and the response of the eardrum to movement is measured. The results are shown graphically on the tympanogram.
Interpretation of the results
There are different types of tympanogram:
Type A: Middle ear pressure and eardrum mobility are normal.
Type B: Fluid in the middle ear or perforation of the eardrum.
Type C: Negative pressure, usually due to dysfunction of the Eustachian tube.
This test is painless and can be completed in a short time. May be recommended by a doctor in case of hearing problems or ear-related disorders.
