Management of surgical complications and failures in acoustic neuroma surgery.

Acoustic neuromas (ANs) are the most common tumors of the cerebellopontine angle. Although numerous advances have occurred in the operative management of AN and perioperative care leading to a significant decrease in associated morbidity and mortality, there are several characteristic complications that accompany microsurgical resection of AN. Understanding the types and rates of complications in association with the various approaches is essential in patient counseling, establishing patient expectations, and ensuring the best patient outcome. In this article, the justification for incomplete surgical resection is discussed. Also, the most common complications of AN microsurgery and the associated management are reviewed.
