Acoustic Neuroma is a benign tumor that arises in the internal auditory canal or just outside the internal auditory canal from the nerve sheath of a vestibular (balance) nerve. This tumor,
as it slowly enlarges, can compress the vestibular (balance) nerves, causing vertigo In the
early part of the tumor's growth, the patient complains of unsteadiness. If compression of the
cochlear (hearing) nerve occurs, there is evidence of a sensorineural hearing loss with very poor
speech discrimination. Tinnitus (ringing in the ear) may also be present. The facial nerve may
be affected, but usually late in the course of this disease. [Northern, 1996]
