What Is an Acoustic Neuroma?

Acoustic neuroma is a noncancerous (benign) and usually slow-growing tumor — not in Sue's case — that develops on the main nerve leading from the inner ear to the brain.

Because branches of this nerve directly influence balance and hearing, pressure from an acoustic neuroma can cause hearing loss, ringing in the ear, and unsteadiness. Large tumors of this type usually require removal by surgery.
