Computed tomography for determining pathways of extension and a staging and treatment system for juvenile...

Computed tomography (CT) has changed the preoperative assessment protocol of juvenile angiofibromas as it shows the extent of the tumor and its pathways of extension. Hence, operation can be done sooner and with minimal blood loss. Using CT scanning in 22 patients with nasopharyngeal angiofibromas, we found different pathways of extension of the tumor. We report a new staging system and surgical approaches, based on the stage of the tumor.
