Juvenile nasopharyngeal angiofibromas and paragangliomas are the most common hypervascular tumors of the head and neck that require embolization as an adjunct to surgery. A detailed understanding of the functional vascular anatomy of the external carotid artery is necessary for safe and effective endovascular therapy. Embolization, using a transarterial technique and particulate agents, a direct puncture technique and liquid embolic agents, or both techniques may allow for complete devascularization of hypervascular tumors of the head and neck. Effective embolization of these tumors results in a significant reduction of blood loss during surgery and allows for complete resection of the tumors. Use of meticulous technique and a thorough knowledge of functional anatomy of the head and neck vasculature are essential.
