Conditions & Treatments
An acoustic neuroma is a benign (non-cancerous), usually slow-growing tumor on the eighth cranial nerve, the main nerve that connects the ear to the brain and controls hearing and balance. Acoustic neuromas grow slowly at their site of origin.
The tumor can push against the brain as it enlarges, but does not invade the brain. Larger tumors can press on the trigeminal nerve or even on the brain stem and cerebellum, threatening vital functions. An acoustic neuroma may also be referred to as a vestibular schwannoma, neurinoma, or neurilemmoma.
Two types of acoustic neuromas:
The most common first symptom of an acoustic neuroma is hearing loss in the tumor ear. Other symptoms may also include tinnitus (ringing in the ears), dizziness, paralysis of a facial nerve, headaches, and loss of balance.
Treatment for acoustic neuromas includes surgical removal, radiation, including Gamma Knife, and watchful waiting.
