Craniofacial resection for anterior skull base tumors.

We present the results of treatment of 30 patients with anterior skull base tumors operated on over an 11-year period. At the time of surgery, intracranial invasion was present in 10 patients. Histology revealed epithelial tumors in 18 patients, sarcoma in 6, esthesioneuroblastoma in 4, and 2 miscellaneous histologies. The overall median survival was 5 years and varied according to histology and grade of tumor. Currently malignancies involving the skull base can be successfully resected using a craniofacial approach, with minimum operative mortality. Limited intracranial invasion need not necessarily represent a major contraindication of this procedure if morbidity can be kept to a minimum.
