An acoustic neuroma is a tumor that grows on the nerve leading from the brainstem to the ear. This nerve plays a role in hearing and in maintaining your balance. An acoustic neuroma grows slowly. It is a benign tumor, which means it is not cancerous. However, this condition can still cause serious problems.

As the tumor grows and/or hearing becomes impaired, removal of the tumor may be necessary. The type of surgery depends on the size and location of the tumor. Complications of surgery may include permanent hearing loss and/or paralysis of facial muscles on the affected side.
Radiation therapy is the use of radiation to kill cells and shrink tumors. Radiation is expected to prevent further growth of the tumor. Radiation may be used when tumors are small and surgery is not possible. This method may preserve hearing. It may be given over several treatments or as one large dose. You may be treated with a procedure called stereotactic radiosurgery . This surgery uses a beam of radiation to destroy the tumor tissue.
