A VEMP test is used to assess the function of the saccule of the inner ear and a portion of the vestibular nerve with connections to the brain. Because the saccule is slightly senstive to sound, it’s function can be measured by presenting a sound into the ears while measuring a response from the muscles in the neck. Responses are measured against normative values. Abnormal responses can indicate saccule disorders or conductive hearing loss. VEMPs are useful in aiding in the diagnosis of superior canal dehiscence and perilymph fistula.
