An acoustic neuroma may cause a variety of permanent complications, including:

  • Hearing loss
  • Facial numbness and weakness
  • Difficulties with balance
  • Ringing in the ear

Large tumors may press on your brainstem, preventing the normal flow of fluid between your brain and spinal cord (cerebrospinal fluid). In this case, fluid can build up in your head (hydrocephalus), increasing the pressure inside your skull.
