Some causes of vertigo, dizziness, or imbalance are related to the ear. If you are experiencing dizziness or balance problems the first step would be to see one of our ENT (ear, nose, and throat) physicians. They may request balance (vestibular) testing to confirm or rule out possible causes of your balance complaints.
Videonystagmography (VNG) evaluates the function of the vestibular portion of the inner ear for patients who are experiencing symptoms of vertigo, unsteadiness, dizziness, and other balance disorders. It is used to assist the physician in diagnosing the cause of the dizziness. This testing is typically done in conjunction with a full medical evaluation and is most often covered by insurance. Hearing evaluation tests are frequently combined with vestibular studies for the identification of inner ear disorders. Other tests that may also be ordered are ABR (Automated Brainstem Response), ECoG (Electrocochleography), and or AEP (Auditory Evoked Potential.
