Endoscopic resection of juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibromas remain rare tumors representing approximately 0.05% of head and neck tumors. The typical presentation is a male teenager with recurrent epistaxis and nasal obstruction. These tumors were traditionally approached via external and/or intraoral incisions, but many are amenable to endoscopic removal. Preoperative embolization of major feeding vessels to these tumors by interventional radiology has resulted in significantly less blood loss and facilitated endoscopic resection. The following chapter discusses endoscopic resection of juvenile nasopharyngeal angiofibromas and outlines pertinent anatomy while covering important surgical techniques. Appropriate patient selection, anesthesia considerations, surgical preparation and techniques, and postoperative care are discussed. A case presentation is included with preoperative imaging and an accompanying video to demonstrate these surgical techniques.
