What Is An Acoustic Neuroma?

Acoustic neuroma, also known as vestibular schwannoma, is a noncancerous tumor that develops on the nerve that connects the ear to the brain. It usually grows slowly and does not spread to other parts of the body, but it can cause hearing loss, ringing in the ears (tinnitus), and balance problems. Other symptoms may include headaches, facial numbness, and difficulty with facial movement.

The cause of acoustic neuroma is not clear, but some risk factors may include having a family history of the condition or having a genetic disorder called neurofibromatosis type 2. Treatment options for acoustic neuroma may include monitoring the tumor for growth, radiation therapy, or surgery to remove the tumor.
