Acoustic neuroma
(vestibular schwannoma)
Acoustic neuroma, also
known as vestibular schwannoma, is a noncancerous and usually slow-growing
tumor that develops on the main (vestibular) nerve leading from your inner ear
to your brain. Branches of this nerve directly influence your balance and
hearing, and pressure from an acoustic neuroma can cause hearing loss, ringing
in your ear and unsteadiness.
Acoustic neuroma
usually arises from the Schwann cells covering this nerve and grows slowly or
not at all. Rarely, it may grow rapidly and become large enough to press
against the brain and interfere with vital functions.
Treatments for
acoustic neuroma include regular monitoring, radiation and surgical removal.
