title: Anterior craniofacial resection - for paranasal sinus tumors involving anterior skull base.
abstract: Management of anterior skull base tumors is complex due to the anatomic detail of the region and the variety of tumors that occur in this area. Currently, the "gold standard" for surgery is the anterior craniofacial approach. Craniofacial resection represents a major advance in the surgical treatment of tumors of the paranasal sinuses involving anterior skull base. It allows wide exposure of the complex anatomical structures at the base of skull permitting monobloc tumor resection. This study presents a series of 18 patients with anterior skull base tumors, treated by a team of head-neck surgeons and neurosurgeons. The series included 15 malignant tumors of the nose and paranasal sinuses and 3 extensive benign lesions. All tumors were resected by a combined bi-frontal craniotomy and rhinotomy. The skull base was closed with a pediculated pericranial flap and a split-thickness free skin graft underneath. There were no postoperative problems of wound infection, cerebrospinal fluid-leakage or meningitis. Recurrent tumor growth or systemic metastasis occurred in 3 out of 15 patients with malignant tumors, 6 months to 2 years postoperatively. Craniofacial resection was thus found to give excellent results with low morbidity in malignant lesions and can also be adapted for benign tumors of anterior skull base.
