ABSTRACT: Acoustic neuroma is a noncancerous (benign) and usually slow-growing tumor that develops on the main nerve leading from your inner ear to your brain. Because branches of this nerve directly influence your balance and hearing loss, ringing in your ear and unsteadiness. Acoustics comprise about 6 percent of all intracranial tumors, about 30% of brainstem tumors, and about 85% of tumors in the region of the cerebellopontine angle- another 10% are meningiomas. The 6% number is probably much too high as meningiomas and pituitary tumors are underreported. Only about 10 acoustic tumors are newly diagnosed each year per million persons, corresponding to between 2000 and 3000 new cases each year worldwide. Another way of looking at this is that a average person has a risk of about 1/1000 of developing an acoustic neuroma in their lifetime. Also known as vestibular schwannoma, acoustic neuroma is an uncommon cause of hearing loss. Acoustic neuroma usually grows slowly or not at ball, but in a few cases it may grow rapidly and become large enough to press against the brain and interfere with vital functions.
