Evaluation of the patient with recurrent vertigo.
The evaluation of the patient with recurrent vertigo requires knowledge of vestibular anatomy and physiology. The patient's medical history and physical examination provide the majority of the information necessary for diagnosis. Many diagnostic tests are available to the clinician to aid in the diagnosis. Videonystagmography is useful for the evaluation of peripheral vestibular function and provides some information about central processes as well. Rotary chair testing provides excellent information about central processes and can aid in diagnosing peripheral vestibular impairment. Vestibular-evoked myogenic potential testing is sensitive for testing inferior vestibular nerve and saccule function. Many different medical and surgical options are available for the patient with recurrent vertigo.
