PEROPERATIVE MAXILLARY ARTERY LIGATION A MEASURE TO REDUCE BLEEDING IN ENDOSCOPIC RESECTION OF JUVENILE ANGIOFIBROMA

Juvenile Angiofibroma

Abstract

Juvenile nasopharyngeal angiofibroma is a rare vascular tumor almost exclusive to the nasopharynx of adolescent males. Young females given this diagnosis should undergo chromosomal studies or should have the diagnosis questioned. Incidence of JNA is 1 case per 5000-60,000 ear, nose, and throat patients and accounts for 0.5% of all head and neck tumors. The wide range of reported cases may stem from misdiagnosis and inclusion of other lesions. Incidence is reported to be higher in Egypt and India
