Acoustic Neuroma Removal

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.

Parts of the Body Involved

Ear canal, head

Reasons for Procedure

Increasing growth of the tumor
Concern that tumor size may become life-threatening
Hearing problems

Risk Factors for Complications during the Procedure

None

What to Expect

Prior to Procedure

You will take the following medications:

Steroids - usually started 48 hours before surgery
Antibiotic - given intravenously (into the vein) right before surgery, and continued for 24 hours after surgery

During Procedure

Outcome

Successful completion of the surgery results in complete removal of the tumor, and minimal additional hearing loss. You should have MRI scans regularly over the next several years to check for recurrence.
