Adequate surgery in the past has been limited by incomplete knowledge of the anatomy of the tumor and technical difficulties related to the vascularity. To better define the tumor, 12 patients with juvenile angiofibroma have been studied by axial and coronal high resolution computed tomography (CT). The extent of the neoplasm was better demonstrated by CT than by other techniques. Based on the CT findings, we propose an anatomic classification that is helpful in determining treatment methods. Nine patients were considered operable, and eight of these underwent preoperative embolization with Silastic spheres and Gelfoam. The preoperative embolization significantly reduced operative difficulty and the necessity for blood transfusions. Based on these cases, we believe the current radiographic management of juvenile angiofibromas should consist of plain films, CT, angiography and, in surgical cases, preoperative embolization. ER -
