[Surgery of the skull base tumor]

Surgery of the skull base tumor has been undertaken in 19 patients, 15 with anterior skull base tumor and 4 lateral skull base tumor. Among them, 16 cases had malignant tumors and 3 had benign tumors. The dura was exposed in 15 patients and resected in 5 patients due to tumor invasion. The dura and bony defects could be repaired with fascia lata, galea pericranial flaps and scalp flaps. Cautery was useful for treating minimally involved duras. Three out of 16 patients with malignant tumors were free of tumors for 4-14 years and 5 for 1.5-3 years postoperatively; 7 cases died of tumor recurrence.
