SURGICAL TECHNIQUE OF ANTERIOR SKULL BASE SURGERY FOR TUMORS INVOLVING THE SKULL BASE

Abstract

The complete removal of tumors involving the anterior skull base has been a very challenging problem due to the severe complications. Recent advances in the technique of craniofacial resection and reconstruction have provided more predictable, functional, and aesthetic results for this challenging surgery, with much lower morbidity rates. Now, anterior skull base surgery is well established and is routinely practiced in neurosurgical and otolrayngological centers in the world. However, postoperative complications remain the most serious issue in craniofacial surgery. Although there has been a trend toward fewer complications, the sequelae are still devastating. In this paper, we described our surgical technique of anterior skull base surgery, which has been performed at University of Tokyo Hospital. The principles of the operation, preoperative preparation, operative technique, after-care and postoperative complications were discussed.
