Neuro-Otology Research

Neuro-otology focuses on the inner ear and its connections in the brain. On the clinical side we evaluate patients with dizziness, imbalance, hearing loss and tinnitus. We have a world renowned clinical laboratory that provides clinicians with detailed measurements of the function of the inner ear in its brain connections. On the research side we study the causes of dizziness and imbalance with particular emphasis on: vestibular migraine, benign paroxysmal positional vertigo, Meniere's disease, familial episodic ataxia, and familial vestibulopathy. We have several genetic research studies in progress and are conducting a placebo controlled treatment trial of rizatriptan for episodes of vestibular migraine.
