What Is Tympanometry?
When you see your Audiologist for a hearing evaluation, several tests will be conducted in order to determine where the hearing loss stems from. Tympanometry is a test used to detect problems occurring in the middle ear.
What Happens During Tympanometry?
The first step in Tympanometry is to check that your ear canals are clear of wax or other debris by looking in your ear canal with a tool called an otoscope (oto means ear). The otoscope allows your Audiologist to look closely at your eardrum and the ear canal.
Next, a small, soft ear bud is placed into your ear canal that will change the air pressure in your ear canal and cause the eardrum to move back and forth. A machine will record how well the ear drum moves.
What Do I Need To Do During Tympanometry?
Tympanometry is really very simple. In fact, you don’t need to do a thing! And, even better, it’ll be over in just a matter of minutes. You can help your Audiologist get good results by not speaking, chewing or swallowing during the test. If you do, it’s not a problem but the best results are obtained when there is little to no movement by the person being tested.
What Will I Feel During Testing?
Tympanometry is not uncomfortable and shouldn’t cause any pain. It may feel a little strange to have the soft ear bud in the ear and the change in air pressure is noticeable, but not any more noticeable than an air pressure change in an airplane. You may hear a soft tone in your ear during testing.
Why Is Tympanometry Performed?
Tympanometry tells your Audiologist about the health of the middle ear system. The middle ear is composed of the three smallest bones in the body: the hammer, anvil and stirrup (or maleus, incus and stapes), some very small muscles and the Eustachian tube; the tube that runs from behind the eardrum down the back of the throat. If something is not allowing the bones to move, hearing loss can occur. Tympanometry is performed to rule out middle ear involvement in hearing loss or to determine if further testing by an ear specialist is needed.
What If My Tympanometry Results are Abnormal?
Tympanometry results that are abnormal can mean many different things. Your Audiologist will use the tympanometry results as one part of the puzzle in determining where your hearing loss is stemming from and what the next best step is. If your results are abnormal, don’t worry! Abnormal results simply mean more testing is needed. If you have a concern, talk to your Audiologist about it. She’ll be able to answer any questions you might have.
