We report seven cases of juvenile nasopharyngeal angiofibromas (6 males and a female, averaged 17.3 years old) treated at Mie University Hospital for 20 years during 1983 and 2003. Tumors ranged from 20 to 90 mm, but these size was not related to tumor stage. In patients, the surgery was performed by a trans-oral (4 cases) or trans-maxillary (3 cases) approach. In two cases, palatal fistula was observed, and later closed surgically. Two recurrent tumors were observed at about one year postoperatively and those cases were successfully underwent surgery again by the trans-maxillary approach. Intraoperative blood loss volume was large in advanced staged cases, but the volume was not related to tumor size. Pre-operative thrombosis via a maxillary artery under angiographic guidance, was performed in each case. This treatment was effective, when performed the day before surgery.
Key words : juvenile nasopharyngeal angiofibroma, pre-operative thrombosis, surgical approach
