Juvenile Nasopharyngeal Angiofibroma: Clinical Factors Associated With Recurrence and Proposal of a Staging System

摘要

Juvenile nasopharyngeal angiofibroma (JNAF) is a rare histologi-cally benign vascular tumor found exclusively in adolescent males. It can be aggressive and locally invasive with a potential of involving vital intracranial structures and is also associated with high rate of recurrence.It is an age-old fact that JNAF grows with finger like projections into natural bony crevices and it is imperative that a wide exposure is achieved to visualize and remove this extensively vascular tumor. These 'touch me not' tumors can be generally completely removed even in Stage III and IV (except Stage FVb tumor) if the surgeon has achieved proper exposure after adequate bone work.
