Dizziness & Balance

Dizziness & Balance
Dizziness can be caused by various problems and involve more than one body system. Based upon your history and physical findings, Dr. Ress may require specialized tests to complete a full evaluation. The testing protocol is determined at the time of examination and may include hearing and balance tests, imaging (CT or MRI scans) and blood tests.

The most common test for dizziness is videonystagmography (VNG). The VNG tests the strength of the inner ear balance function as well as the coordination of eye movements.

It involves watching the eye movements after placing warm or cool air into the ear canal. It typically causes a brief episode of dizziness during the test. Other tests include electrocochleography (ECoG) and Vestibular Evoked Myogenic Potentials (VEMP).

These painless tests evaluate other parts of the inner ear. The object of this evaluation is to be certain that there is no serious or life threatening disease and to pinpoint the exact site of the problem. This lays the groundwork for effective medical or surgical treatment.
