Middle Ear Tests

The purpose of impedance audiometry is to determine the status of the tympanic membrane (ear drum) and middle ear via tympanometry. It is a measurement of energy or air pressure flow, which involves the ear canal, eardrum, ossicular chain, tensor tympani, stapedius muscle, cochlea, CNs VII and VIII, and the brainstem.
