Abstract：
:Juvenile nasopharyngeal angiofibroma (JNA) is the most common benign tumor of the nasopharynx. For reasons unknown, this tumor is found almost always in male population. However, site of origin of JNA is still an enigma. Previously, JNA was considered to arise from the superior aspect of sphenopalatine foramen. Over last decade, the vidian canal was considered to be the more specific and likely site of origin. However, based on our observations, we believe this hypothesis to be anomalous as it does not explain major blood supply, pattern of skull base erosion in early stage of tumor and newer studies on electron microscopic and immunopathological findings. To explain these anomalies, we hypothesize the site of origin to be palato-vaginal canal.
