An acoustic neuroma is a slow-growing, benign tumor in the inner ear. This tumor presses on the nerves of the inner ear, negatively impacting hearing and balance. As an acoustic neuroma tumor continues to grow, it can begin to put pressure on certain parts of the brain. If this continues, the acoustic neuroma can become life-threatening.
To remove an acoustic neuroma, surgery is performed. In some cases, Gamma Knife radiosurgery is performed to help stop the growth of the tumor.
