Acoustic neuroma is a rare, noncancerous tumor that develops on the main nerve connecting the ear to the brain. The tumor grows slowly and presses on the hearing and balance nerves in the inner ear. This pressure can cause hearing loss, ringing in the ear and loss of balance. Acoustic neuroma is also called a vestibular schwannoma, as it is caused by the overproduction of Schwann cells in the nervous system.
