경비 내시경 수술로 제거한 유년성 비인강혈관섬유종 3례

Juvenile nasophayngeal angiofibroma (JNA) is a histologically benign but highly vascular, agressively expansile lesion that occurs exclusively in prepubescent or pubescent males. Traditional treatmemt of huge JNA has included open surgical approaches for majority of tumors. Recent development in endoscopic approaches enabled surgeons to avoid complications and to reduce the morbidity following major operation. Preoperative embolization is useful for reducing intraoperative blood loss and the risk of incomplete excision of the tumors. This report describes three cases of JNA treated by transnasal endoscopic approach with or without preoperative embolization. The tumors were completely removed without complications, and there was no evidence of recurrence during 6-10 months of endoscopic follow-up. (J Clinical Otolaryngol 2001;12:104-109)
