Recently, we experienced a case of juvenile nasopharyngeal angiofibroma. The patient was a 15-year-old male who complained of right nasal obstruction. Rhinoscopic examination and CT scan were performed. A vascular tumor derived from the nasopharynx was found to extend through the right ethmoid, sphenoid and maxillary sinuses. Angiography revealed that the main supply of blood to the tumor was from right maxillary artery. Radiation therapy (total 3200 rad) was performed, but it was ineffective. Therefore, superselective catheterization to the base of the tumor and transcatheter arterial embolization were performed. The tumor was then successfully removed by the transpalatine approach. The volume of bleeding during the operation was less than 50ml and there was no post-operative bleeding. Pre-operative embolization with gelfoam was found to be an effective method for reducing blood loss during surgery for this tumor.
