✦ Synopsis

Objectives

Juvenile nasopharyngeal angiofibroma is a intranasal vascular tumor that has traditionally been resected through open craniofacial approaches. Recently, however, such tumors have been successfully resected via endoscopic approaches in part due to the use of preoperative embolization. The purpose of this study is to describe the normal vascular supply of JNA and to report a case series on several anatomic variants. Knowledge of these variants should help preoperative planning and avoidance of complications.

At the conclusion of this presentation, the participants should be able to demonstrate an understanding of the normal vascular supply of juvenile nasopharyngeal angiofibromas as well as the frequency and clinical importance of less common anatomical variants.

## Abstract ## Objectives: Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign tumor of the nasopharynx, exclusively affecting males in their teens and twenties. Historically, it has been thought that JNAs primarily receive their blood supply from the ipsilateral external carotid system.

## Abstract Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign neoplasm of the nasopharynx that accounts for 0.5% of all head and neck tumors. Although histologically benign in appearance, JNAs are locally aggressive and destructive, spreading from the nasal cavity to the nasopharynx, para
