비중격에 발생한 비인강 외 혈관섬유종 2예

Nasopharyngeal angiofibromas are locally aggressive tumors arise predominantly from pterigopalatine fossa. Extranasopharyngeal angiofibromas arising from the nasal septum are extremely rare. Only 15 cases have been reported in the international literature, but not in Korea. We experienced two cases of extranasopharyngeal angiofibroma occurring on the nasal septum and the tumors were successfully removed by endoscopic approach without massive bleeding. The theory of origin of the tumor and its management is discussed with review of literature. (J Clinical Otolaryngol 2013;24:80–84)
