David Eisenman, M.D.

Director, Otology and Neurotology Program

David Eisenman

Dr. Eisenman became director of the Otology and Neurotology Program in July, 2005. Prior to coming to UMMC, he spent two years as the Chief of Otology & Neurotology at the Walter Reed Army Medical Center in Washington, DC, and three years in private practice in Washington, DC. At Walter Reed he was instrumental in creation of a cochlear implant program, and a multidisciplinary, integrated balance disorder center. He has delivered numerous invited lectures on topics in the field of hearing, balance and facial nerve disorders to students, residents and health care practitioners.

Dr. Eisenman received his MD from the Yale University School of Medicine in 1992. While at Yale, he was awarded the Logan-Clendening Traveling Fellowship for research in the History of Medicine. He also spent an additional year at Yale working in the Laboratory of Developmental Respiratory Neurophysiology. Dr. Eisenman then completed 2 years of General Surgery training at the New York Hospital Cornell University Medical Center, and four years in Otolaryngology-Head & Neck Surgery at the Manhattan Eye, Ear and Throat Hospital. From there he went to the University of Michigan for fellowship training in Neurotology and Skull Base Surgery, where he also performed and published his research in recovery from inner ear and vestibular injuries, and in cochlear implantation.

Dr. Eisenman specializes in diseases of the ear and lateral skull base. These include evaluation and treatment -- both medical and surgical -- of hearing loss, balance and vestibular disorders, facial nerve paralysis, chronic ear infections, and skull base tumors. Some specific disorders included in these are acoustic neuroma (vestibular schwannoma), otosclerosis, eardrum perforation, cholesteatoma, ear and temporal bone trauma, Bell's palsy and facial nerve tumors, Meniere's disease and other forms of endolymphatic hydrops, benign paroxysmal positional vertigo (BPPV) and migraine-associated vertigo.
