Abstract

INTRODUCTION: Nasopharyngeal angiofibroma is a rare histologically benign tumor which occurs almost exclusively in adolescent boys. The morbidity and mortality associated with this tumor are related to its prominent vascularity and its propensity for aggresive local growth. MATERIALS AND METHOD: From November 1990 through February 1996, 8 patients with a diagnosis of nasopharyngeal angiofibroma were managed at Asan Medical Center. For the devasculation of the tumor before the surgery, preoperative arterial embolization was performed on 6 patients.
RESULTS
The main tumor supplying vessel was ipsilateral internal maxillary artery in all cases. According to Chandler classfication(Table 1), stage II was 4 cases and stage III was 4 cases. Operative procedures were midfacial degloving approach(4 cases), transpalatal approach(1 case), transantral approach(1 case), combined approach(1 case: Caldwell-Luc op & endoscopic op), medial maxillectomy(1 case). There were no treatment-related deaths and no major surgical complications.
