Abstract： Objective To explore the methods for endoscopy nasal microsurgery and multiple techniques in treatment of nasopharyngeal angiofibromas. Methods CT, MRI and digial substraction angiography (DSA) and endoscopic examination had been used. ALL 12 patients accepted preoperative feeding artery embolum, hypotention anesthesia and injected adrenaline-lidocaine. Microelectrotomy-electrocoagulation had been used to remove tumor. Results All patients were treated by endoscopic nasal surgery. No complications had occurred. No recurrence were found in follow-up period. Conclusion The important factors to reduce amount of introperative bleeding are to select proper operative patients and use multiple techniques. Endoscopy nasal surgery has dominance in reducing complications, wound, tumor recurrence, operative time and nasal function.
