Tympanometry

In the Clinic

Tympanometry is a test that I use in only a couple of highly specific situations. The test is done by taking a small hand held device (see picture) which when placed in the ear, emits a sound wave that checks the integrity of the eardrum. It helps assess Eustachian Tube (the tube from the inner ear to the nasal cavity) function. It tells me if there is abnormal pressure in the ear or if there is fluid behind the eardrum.


I do this in children that have allergies and in individuals that are going to take Hyperbaric Oxygen to see if their Eustachian tube is functioning properly so I know in advance if they will have trouble equilibrating pressure in the HBO Chamber. If they do, we simply suggest a squirt of a nasal decongestant like Afrin into the nose 30-45 minutes prior to treatment.
