Recovery period of sinonasal quality of life and its associated factors after endoscopic endonasal approach for anterior skull base tumors

Although endoscopic endonasal approach (EEA) for skull base tumors showed a good prognosis in sinonasal quality of life (QOL), what factors have influence on QOL is still in question. Aim/Objectives: To investigate the recovery of sinonasal QOL after EEA for anterior skull base tumors and find its prognostic factors.The study enrolled 250 patients undergoing EEA for anterior skull base tumors over 3 years. Sinonasal QOL was evaluated via sinonasal outcome test (SNOT-22) during 6 months. Age, gender, previous surgery, surgical extent, tumor pathology, combined surgical procedures, and surgical complications were analyzed.There were 101 male and 149 female with average 48.6 ± 16.1 years old. SNOT-22 increased from baseline (median 17.0; QSinonasal QOL was recovered within 6 months. Avoidance of calcium hydroxyapatite could prevent delayed recovery. Surgeons should carefully manipulate nasal mucosa to minimize postoperative mucosal edema.
