Managing Vascular Tumors-Open Approaches

Abstract

The most common vascular tumors encountered by the otolaryngologist are rare chromaffin cell tumors termed paragangliomas. Within the head and neck region, they commonly arise from the carotid body, vagus nerve (glomus vagale), and jugular vein (glomus jugulare). Other vascular head and neck tumors include sinonasal malignancies, because of proximity to or involvement of the pterygoid plexus as well as the rich vascularity of the sinonasal mucosa; juvenile nasopharyngeal angiofibroma, a vascular tumor of male adolescents; unusual vascular tumors such as hemangiopericytoma; and metastatic renal cell cancer, which has a proclivity for an unusually rich blood supply.
