What is the Tympanometry test? 

The eardrum is a layer that divides the ear canal from the inner ear and is essential for hearing. The eardrum vibrates when sound travels through the ear canal. Tiny bones sense this vibration and transfer it to the inner ear and nerve system, where the brain processes it. Eardrum disorders ranging from infection to perforation may severely affect your hearing ability. As a hearing aid provider, we perform a variety of tests at our clinic to help you get the right hearing aid under budget. 

Tympanometry is a medical word that refers to a test that evaluates the function and mobility of the eardrum and middle ear. The examination is typically rapid and painless unless the eardrum or middle ear is inflamed. Tympanometry data are plotted on a graph called a tympanogram by our experts to examine the results.

Why Tympanometry test? 

Tympanometry is often used to identify or rule out the presence of fluid in the middle ear, a middle ear infection, a rupture in the eardrum, or Eustachian tube malfunction. This test is critical for children with suspected middle ear difficulties. Still, it is also sometimes done to adults as part of a standard hearing examination to evaluate whether any middle ear disorders are contributing to hearing loss.

Typically, adults and children seeking medical approval for hearing aids undergo a tympanometry exam. This ailment is almost typically transient and treated medically. The most frequent reason for an irregular tympanogram is fluid behind the eardrum, which inhibits the eardrum from moving and transmitting sound adequately.

You may not even need hearing aids to correct your hearing loss if you have fluid in your ear; nonetheless, to choose the best course of treatment, you should see your physician or a local hearing health professional.

Our Tympanometry test procedure

Functions of Tympanometry

Tympanometry is advantageous for diagnosing ear issues that might result in hearing loss, particularly in youngsters. Your doctor may use The test to assess if you have:

  • A middle ear infection, often known as otitis media.
  • Middle ear fluid
  • Perforations in the tympanic membrane
  • Complications with the Eustachian tube link the upper neck and nose to the middle ear.

The test may be performed every few weeks for many months to see how much fluid has built up in the middle ear. Adults often undertake the test as part of a standard hearing examination to rule out middle ear disorders. A tympanogram depicts the eardrum’s reaction to variations in air pressure inside the ear canal.

Normal readings

When the measurements are within the usual range, the line takes on the appearance of a “mountain” as the eardrum reacts to the stimulation. The normal results indicate the following:

  • The eardrums are normal in their movement 
  • In the middle ear, there is no fluid.
  • Normal mobility of the eardrums and ossicles (tiny bones in the middle ear that help to hear).

For toddlers and adults, the normal pressure within the middle ear is between +50 and -50 daPA.‌ Our Audiologists perform the test carefully to ensure best results everytime. 

Abnormal readings

If the measurements are irregular, the line may extend beyond or before the 0 daPa level. If the eardrum is not sensitive, the line will be flat due to perforation or fluid. Other possible explanations for the tympanometry findings include the following:

  • Eardrum scarring, which occurs as a result of ear infections
  • Excessive pressure in the middle ear
  • Middle ear growths
  • Immobility and other disorders affecting the middle ear’s ossicles
  • Blockage of the eardrum by earwax

Hearing aids may be ineffective in correcting your hearing loss if fluid or earwax obstructs the eardrum. Rather than that, it would help if you visited your physician to determine the best course of action. If your physician detects an illness other than those listed above, they may send you for more testing and expert treatment.

How is A Tympanometry Test Done?

To begin, our ear specialist will do an ear examination, or otoscopy, using an otoscope. This assists in determining if the auditory system is clear and unperforated. Additionally, it aids in determining if wax or other items are clogging the ear canal.

Our hearing experts will insert a tympanometry instrument into the ear canal. The gadget alters the air pressure within the ear, producing a pure tone that measures the eardrum’s reaction to noises at various pressures. As the equipment starts to collect measurements, it may emit loud tones. You will be unable to move, swallow, or talk throughout the test since doing so may result in an erroneous result.

2 minutes and it’s done

The test takes around two minutes for each ear and is performed in the doctor’s office. Although it is a safe technique for individuals of all ages, it may be challenging for little infants who cannot participate.

If your kid is scheduled for tympanometry, it is beneficial to inform them in advance of what to anticipate. For instance, you may show what will occur throughout the test using a doll. It will help them develop their ability to stay calm and prepare them for loud sounds. There are no known dangers associated with the surgery.

What Happens After Tympanometry Testing?

Tympanometry is a test that looks for indicators of middle ear disorders. Typically, abnormal findings are the consequence of middle ear fluid. More testing may be necessary if the findings are consistently abnormal and the issue is not just fluid behind the eardrum. Further testing may be required to clear out other ear problems. Whether you are having mild hearing issues or not able to hear at all, we are here to assist you with the right hearing aids at the most competitive rates.
