An acoustic neuroma is a benign (non-cancerous) tumor on the acoustic nerve leading from the brain to the ear. Acoustic neuromas grow relatively slowly, and may cause hearing loss, balance problems, facial numbness, and headaches.
There are three main treatment options for an acoustic neuroma:
- Careful monitoring
- Microsurgical removal
- Radiation
This fact sheet focuses on microsurgical removal of an acoustic neuroma.
