Abstract
Juvenile nasopharyngeal angiofibroma is a highly vascular neoplasm that lends to spread in the various fissures and foramina of the nasopharynx. Polytomography and angiography have added greatly to the diagnosis and management of this tumor through accurate preoperative assessment. Computed tomography has given an additional sophisticated, precise method for evaluating the extent of juvenile nasopharyngeal angiofibroma. Computed tomography shows, in detail, the extension of the tumor into the pterygopalatine fossa with widening of the pterygopalatine fossa and anterior bowing of the posterior wall of the maxillary sinus. With this correct information about tumor location, surgical or radiation treatment can be appropriately planned, with a probable improvement of cure rates and reduction of recurrences.
