Acoustic Neuroma

Medically reviewed by Last updated on Jan 5, 2023.


An acoustic neuroma (AN)

is a slow growing, benign (not cancer) tumor. The tumor grows on the nerves that control balance, hearing, and feeling in your face. AN also grows on the nerve that moves muscles used for chewing. Rarely, it grows large enough and blocks fluid from going to your brain. Normally, it only affects one ear.

Ear Anatomy

Common symptoms include the following:

  • Partial or total hearing loss in one ear
  • Numbness, weakness, or twitching on one side of your face
  • Ringing in your ear
  • Dizziness, poor balance, or trouble walking
  • Full feeling or pain in your ear
  • Headaches or trouble chewing

Contact your healthcare provider if:

  • Your symptoms get worse.
  • Your symptoms return after treatment.
  • You have questions or concerns about your condition or care.

Treatment for AN

depends on how severe your symptoms are and the size of the tumor. Treatment may also depend on your age. You may not need treatment if the tumor is small. Your healthcare provider may want to monitor your AN with regular MRI scans. You may need surgery to remove all or part of your AN. You may, instead, need radiation treatment to shrink your AN.
