Acoustic Tumors and Nerve Disorders Acoustic Tumors N oncancerous, fibrous growths that originate from the balance or hearing nerve occur in a pproximately 1 of every 1 Americans These vestibular schwannomas (acoustic tumors) and are located deep inside the skull adjacent to vital brain centers. Treatment depends, in part, on the size of the tumor. In an extremely rare genetic condition, Neurofibromatosis Type II, NF-2 , individuals develop benign tumors on both auditory nerves, usually in early adulthood. Surgical removal of these tumors may require the severance of the hearing nerve an profound deafness may result. Because the sound pathway to the brain has been disconnected, conventional hearing aids or cochlear implants are of no assistance. In order to provide NF2 patients with useful sound information, HEI developed the multi-channel auditory brainstem implant (ABI) which was approved b the FDA in October 2000. Overall
