Vestibular Testing (Hearing and Balance studies)

Audiometry & Tympanometry: These are general hearing tests which involve listening to different frequency tones at varying intensity to detect your hearing thresholds and to measure other auditory functions.

Brainstem auditory responses (BAER): These tests use clicking sounds delivered from headphones which in turn stimulate the auditory nerves. There are electrodes are placed behind the ears and on your head to record the small responses from the auditory nerves.  You are relaxed and lying quietly during this test and you do not need to concentrate on the stimuli.

Vestibular evoked potentials (VEMP): These tests measure the responses of the balance system by placing small electrodes over your neck and facial muscles after clicking sounds are heard through headphones or after light taps on your forehead.

Ocular vestibular evoked myogenic potential studies (OVEMPs) are a novel technique which add to the information forthcoming from cervical VEMP studies (cVEMPs) by assessing lesions affecting the otoliths, superior vestibular nerves, 4th cranial nerves and their intrinsic brainstem connections.

Video Head-Impluse Testing (vHITs): You will be fitted with a pair of light-weight and tightly-fitting goggles with a silvered mirror which reflects the image of your eye into a very small camera. You will be asked to fixate on a target while the technician gives your head quick horizontal and vertical head rotations at a very small angle of only 10-20 degrees. The small sensor in the googles measures your head and eye movements. This test is used in the assessment of patients with complaints of dizziness, disequilibrium and vertigo.
