Advances in craniofacial tumor surgery.

The use of craniofacial surgical techniques has stimulated the development of new approaches to the excision of skull base tumors. Experience gained from operating on 200 skull base tumors (45 nonmalignant and 155 malignant) is presented. The cranial base area is subdivided into specific areas, and surgical approaches have been devised. In addition, the use of vascularized tissue such as the galea, temporalis fascia, temporalis muscle, or free vascularized tissue transfer has prevented the complication of infection so frequently seen as a cause for morbidity and mortality in the past. In this series, there were no major infections. The variety of pathology seen in this area is considerable. Therefore, in a series such as this operated on by a single surgeon, only trends can be observed. We suggest that with experience, surgery in this area is safe, and the long-term survival of this mixture of tumors (primary, recurrent, carcinomas, and sarcomas) is between 40% and 50%, and, therefore, makes excisional procedures worthwhile.
