Auditory Evoked Potential Testing

Evoked potential testing consists of objective tests.  Patient response is not required.

ABR

An Auditory Brainstem Response (ABR) evaluation  is a test of the function of the auditory nerve and its pathways to the brainstem.  During the test, you will have electrodes placed on your forehead and earlobes.  You will be asked to lie down and relax while listening to a repetitive click stimulus. You will not be required to respond.  The electrodes will collect data as the signal is transmitted along the auditory nerve to your brainstem.  This test is often used to screen for lesions along the auditory nerve or other retrocochlear disorders.
Approximate test time:  30 minutes

VEMP

The Vestibular Evoked Myogenic Potention (VEMP) evaluation is designed to measure the vestibular portion of the auditory nerve.  The vestibular portion can be be measured during  contraction of certain neck muscles while listening to an auditory stimulus.  Electrodes will be placed on your forehead and neck to monitor the responses of the vestibular nerve.  During the testing, you will be asked to lie down and briefly hold your head in an elevated position during which time an auditory stimulus will be presented to one ear at a time.
Approximate test time:  10 minutes

ECochG

The Electocochleography (ECochG) is used to help diagnose conditions such as Meniere's disease or endolymphatic hydrops.  It may also be useful in diagnosing vestibular migraine or other central vestibular disorders.  As in the VEMP and ABR, electrodes will be used to pick up neurological responses to an auditory stimuls.  You will be asked to lie down and relax (or sleep if possible) while listening to an auditory click stimulus.
Approximate test time:  20 minutes
