Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign and locally invasive tumor. Massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. Endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. In this article, we r...
