What is the main purpose of tympanometry?

The main purpose of tympanometry is to check the compliance of the eardrum, which is essential in evaluating middle ear function. This procedure involves using a device to assess how well the eardrum moves in response to changes in air pressure. By measuring the mobility of the eardrum, tympanometry can help determine if there is fluid in the middle ear, eustachian tube dysfunction, or other conditions that might affect hearing.

This assessment provides valuable information about the status of the middle ear and the eustachian tube, functions that can impact overall hearing ability. An abnormal tympanogram can indicate various issues such as otitis media or tympanic membrane perforation. Therefore, tympanometry serves as a critical tool for audiologists and hearing healthcare professionals in diagnosing and managing ear disorders.
