PEROPERATIVE MAXILLARY ARTERY LIGATION A MEASURE TO REDUCE BLEEDING IN ENDOSCOPIC RESECTION OF 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.It often acts in a malignant manner by eroding into the surrounding sinuses, orbit, or cranial vault. Traditionally, juvenile nasopharyngeal angiofibroma has been treated surgically using open surgical approaches and has been associated with frustratingly high blood loss and recurrence rates. Presently the endoscopic surgery is employed more commonly with preoperative embolisation. This article reviews ligation of maxillary artery a simple measure to reduce the blood loss during the surgery.
