Acoustic neuroma

Overview

Acoustic neuroma, also known as vestibular schwannoma, is a noncancerous and usually slow-growing tumor that develops on the main (vestibular) nerve leading from your inner ear to your brain. Branches of this nerve directly influence your balance and hearing, and pressure from an acoustic neuroma can cause hearing loss, ringing in your ear and unsteadiness.

Acoustic neuroma usually arises from the Schwann cells covering this nerve and grows slowly or not at all. Rarely, it may grow rapidly and become large enough to press against the brain and interfere with vital functions.

Treatments for acoustic neuroma include regular monitoring, radiation and surgical removal.



Symptoms

Signs and symptoms of acoustic neuroma are often easy to miss and may take many years to develop. They usually happen because of the tumor's effects on the hearing and balance nerves. Pressure from the tumor on nearby nerves controlling facial muscles and sensation (facial and trigeminal nerves), nearby blood vessels, or brain structures may also cause problems.

As the tumor grows, it may cause more noticeable or severe signs and symptoms.

Common signs and symptoms of acoustic neuroma include:

  • Hearing loss, usually gradually worsening over months to years — although in rare cases sudden — and occurring on only one side or more severe on one side
  • Ringing (tinnitus) in the affected ear
  • Unsteadiness or loss of balance
  • Dizziness (vertigo)
  • Facial numbness and weakness or loss of muscle movement

In rare cases, an acoustic neuroma may grow large enough to compress the brainstem and become life-threatening.
