An acoustic neuroma, also known as a vestibular schwannoma, is a rare, noncancerous tumor that often affects middle-aged people. It usually grows slowly or not at all and is caused by an overproduction of Schwann cells. If the tumor grows rapidly, it may become large enough to press against the facial nerve or the brain and interfere with vital brain functions
Common symptoms of an acoustic neuroma include:
Continuous exposure to loud noise, such as music or work related noise, and neck or face radiation can lead to an acoustic neuroma. An acoustic neuroma could also be the result of a disease called neurofibromatosis type 3 (NF2). NF2 can be inherited, and individuals with the condition could be at greater risk. About 95% of acoustic neuromas occur spontaneously without any evidence of family history.
Treatments for acoustic neuromas differ depending on the patient's age and health history and the size of the tumor. Treatment options for an acoustic neuroma include:
