Tympanometry

Also known as: tympanogram

What is tympanometry?

Tympanometry measures the movements of a thin layer of tissue between the middle and outer ear known as the tympanic membrane. The results of the test can determine if a disorder that leads to hearing loss is present, such as an infection, tear, fluid or Eustachian tube problems.

What happens during the procedure?

A probe is placed inside the ear that produces loud sounds. The movements of the tympanic membrane are measured as the sounds are produced. The test only takes a few minutes to conduct.

Is any special preparation needed?

The ears need to be checked to ensure that they are free of debris and obstructions. Children may need to be prepared for the test with discussion or a sample test performed on a doll.

What are the risk factors?

There are no risks related to the test.
