Juvenile nasopharyngeal angiofibroma(JNA) is a rare head and neck tumor with high recurence. We retrospectively reviewed 18 cases of juvenile nasopharyngeal angiofibroma managed at Yonsei University Severance Hospital from January 1970 to February 1994 to analyze the clinical behavior, effect of different treatment modalities, recurrence according to the various surgical approach and Sesson's tumor staging, and treatment in recurred cases. Sphenoid and maxillary sinuses were common extension sites. Recurrence rate was 33.3% in Sesson's I, 3.3% in Sesson's II and no recurrence in Sesson's III. Treatment in recurred cases was composed of surgery or radiation. Our result indicates that complete surgical excision can be the most important factor to reduce the recurrence rate.
