Endoscopic resection of juvenile nasopharyngeal angiofibromas

Juvenile nasopharyngeal angiofibromas (JNAs) are a rare, highly vascular benign tumor affecting adolescent males. Recent advances in endoscopic visualization and technique have allowed for complete extirpation of these tumors endoscopically. Proponents of this approach find benefit in the lack of facial incisions, decreased intraoperative blood loss, and excellent tumor control. This chapter describes the endoscopic approach to JNAs.
