Surgery

The surgical approach to removing an acoustic neuroma depends on the tumor’s size and position.

All approaches involve creating an opening through the bony skull. If a microsurgical approach is used, the surgical team makes a small hole, about the size of a dime, behind the mastoid bone. The team then inserts thin, flexible endoscopic instruments through the hole to access and remove the tumor.

Outcomes of surgery depend on the size and adherence of the tumor, the use of cranial nerve monitoring, and the skill of the surgical team.
