Tympanometry is a quick and non-invasive hearing test used to assess the condition of the middle ear and the mobility of the eardrum (tympanic membrane). Rather than measuring hearing sensitivity directly, it evaluates how well the eardrum responds to changes in air pressure. This helps identify problems such as fluid in the middle ear, ear infections, perforations, or issues with the Eustachian tube.
During the test, a small probe is gently placed into the ear canal, creating a seal. The device then changes the air pressure inside the ear while emitting a tone. A sensor measures how the eardrum moves in response to these pressure variations. The results are displayed as a graph called a tympanogram, which shows the level of eardrum compliance at different pressures.
Tympanometry is commonly used for adults, especially when symptoms like hearing loss, ear pain, or a feeling of fullness in the ear are present. It is painless, takes only a few minutes, and requires minimal cooperation.
Overall, tympanometry provides valuable information about middle ear function and helps healthcare professionals diagnose and manage a range of ear-related conditions effectively.
