The Department of Otolaryngology offers a wide range of diagnostic testing to assess the complete balance/vestibular system.
Vestibular Rehabilitation services are coordinated with the outpatient physical therapy department.
Videonystagmography (VNG): VNG is a battery of eye-movement tests that look for signs of vestibular dysfunction or neurological problems by measuring nystagmus. VNG tests are commonly administered to people with dizziness, vertigo, and/or balance disorders. One test evaluates the movement of the eyes as they follow a moving target. Another observes eye movements as the head is positioned in different directions. During the caloric test warm or cold air is circulated in the ear canal. The temperature change stimulates the inner ear in order to test the nystagmus response.
Rotary Chair: Rotation tests are another way of evaluating how well the eyes and inner ear work together. The inner ear sends signals about head movement to the brain, causing signals to be sent to the muscles of the eyes via the vestibulo-ocular reflex . With rotation tests eye movements are recorded while the head is moving at various speeds. This provides additional information, beyond the VNG, about how well the balance organs are functioning, along with their connections to the eye muscles.
Vestibular Evoked Myogenic Potential (VEMP): VEMP testing is used to evaluate whether the saccule and the inferior vestibular nerve are intact and functioning normally. During testing, headphones are used and small electrodes are attached with an adhesive to the skin over the neck muscles. When sound is transmitted through the headphones, the electrodes record the response of the vestibular nerve.
Electrocochleographgy (ECochG): This examination stimulates the acoustic nerve using acoustic click stimulus. measures how sound signals move from the ear along the beginning of the hearing nerve The response is measured either in the ear canal or on the tympanic membrane.
