An acoustic neuroma is a benign tumor, usually stemming from the balance nerve, which travels from the brainstem to the inner ear. It is also called a vestibular schwannoma. This tumor is often diagnosed when patients experience unilateral hearing loss. Management options included surgical removal, radio surgery (e.g. with the Cyberknife), and "watchful waiting."
There are three main surgical approaches designed specifically for removing acoustic neuromas. Dr. Jean uses all three, including the retrosigmoid, middle fossa, and translabyrinthine approaches. He believes that the operation must be tailored to the individual patient's needs and tumor characteristics.
