What is Tympanometry Test?
Tympanometry is a diagnostic test used to assess the condition of the middle ear and diagnose various ear-related disorders. While tympanometry itself does not provide a specific diagnosis, it provides valuable information about the function and mobility of the eardrum (tympanic membrane) and the middle ear.
Tympanometry test provides valuable information about conditions such as fluid buildup, eardrum perforation, and stiffness of the middle ear. By examining the resulting graph called a tympanogram, hearing healthcare professionals can identify abnormalities and determine appropriate treatment strategies.
Why Do We Need Tympanometry Tests?
Tympanometry test is a routine audiological test that is also helpful in diagnosing conditions involving your middle ear that may cause hearing loss.
How is Tympanometry Test Performed?
During the tympanometry test, you sit upright refraining from any movement. The audiologist performs an ear examination by looking inside your ear using an otoscope. The probe has a soft end that seals inside your ear canal and further sends air into your ear emitting a low tone. The microphone on the probe records how your eardrum moves in response to the sound and the air pressure. The tympanometer creates a graph called a tympanogram showing the movement of your eardrum.
What are the Benefits of Tympanometry Test?
1. Tympanometry helps in providing useful quantitative information about the fluid presence in the middle ear, mobility of the middle ear system, and ear canal volume.
2. Tympanometry measures the movement of the eardrum at the time of an ear infection in the middle ear.
FAQ Related to Tympanometry Test
Tympanometry is a diagnostic test used for measuring your eardrum’s movement in response to changes in air pressure. It helps diagnose conditions such as otitis media (middle ear infection), Eustachian tube dysfunction, tympanic membrane perforation, and conductive hearing loss by assessing the middle ear’s function and fluid presence.
The normal range for a tympanogram test is typically between -100 and +60daPa (decaPascals). This range indicates normal middle ear pressure and mobility of the eardrum. Values outside this range may suggest abnormalities in the middle ear function, requiring further evaluation.
A normal tympanometry result typically shows a Type A tympanogram. This indicates that the middle ear system is functioning properly, with normal mobility of the eardrum and normal pressure within the middle ear. Such a test suggests no significant issues with the middle ear function.
Tympanometry is a diagnostic test used to assess the condition and function of your middle ear. When an audiologist performs the test, they measure the movement of the eardrum in response to changes in air pressure, helping to identify issues like fluid accumulation, blockages, or eardrum abnormalities that can affect hearing.
