What type of testing is typically used to evaluate the function of the middle ear?

Tympanometry is a specific type of testing used to evaluate the function of the middle ear by measuring the movement of the eardrum (tympanic membrane) in response to changes in air pressure. This test helps identify any issues such as fluid in the middle ear, eustachian tube dysfunction, or the presence of perforations in the eardrum. The results are displayed on a tympanogram, which provides vital information about the middle ear's status and can indicate whether the middle ear is functioning normally or if there are issues that need to be addressed.

In contrast, auditory brainstem response testing primarily assesses the auditory nerve and brainstem pathways, not the function of the middle ear. Pure-tone audiometry measures the ability to hear specific frequencies and intensities, helping determine the presence and degree of hearing loss but does not provide direct information about the middle ear's status. Speech audiometry evaluates a person's ability to hear and understand speech, focusing on speech comprehension rather than the mechanical function of the middle ear. Therefore, tympanometry stands out as the most appropriate choice for evaluating middle ear function.
