In spite of increasing experience with skull base surgery, some of the guidelines for indications for operations may vary according to the institution. One-hundred two patients underwent craniofacial oncologic resections at our institution from 1982 to 1995. A retrospective analysis of the indications for and contraindications to these procedures was undertaken. The main indications for malignant tumors were skin lesions with direct invasion of the anterior or lateral skull base (69%) and nasal-paranasal sinus tumors (21%). The main indications for benign tumors were glomus lesions (26%), menigiomas (22%), and fibro-osseous lesions of the anterior skull base (19%). The main contraindications were extensive invasion of the central nervous system, invasion of the cavernous sinus and/or internal carotid artery by aggressive malignancies, and bilateral orbital invasion in a nonblind patient. Also, 6 patients had their procedures interrupted during craniotomy for several reasons - extensive central nervous system invasion (2 cases), bilateral orbital invasion (1), lack of brain retraction (1), lack of histologic diagnosis during the operation (1), and purulent discharge at the frontal sinus (1). Craniofacial oncologic operations are extensive surgical procedures that have to be properly indicated in order to obtain low levels of morbidity and mortality. The selection of cases is of paramount importance. In some instances, it seems advisable even to interrupt these operations in the first phase. |
