[Transglabellar, transorbital approach for anterior skull base tumors].

Transglabellar, transorbital approach through the bottom of the frontal sinus for tumours invading anterior skull base in presented. Exposure was improved by rhinectomy and lateral swing of the nose. The most common tumours in the group of 11 patients were squamous cell carcinoma (4) and olfactory neuroblastoma (4). Skull base was excised en block with partial maxillectomy in 8 patients and with total maxillectomy in 3 patients. Orbitectomy was performed in 6 cases. Dura defect was closed with fascia lata and fibrin glue. No serious complications after surgery developed. Rhinoscopy and computed tomography demonstrated clear cavity and no dura prolapse. Transglabellar, transorbital approach provides good exposure for anterior skull base tumours excision and repair.
