Juvenile nasopharyngeal angiofibroma: long-term results in preoperative embolized and non-embolized patients.

A treatment and follow-up study of 32 patients with juvenile nasopharyngeal angiofibroma (JNA) was performed at our clinic between 1974 and 1998. The majority had undergone surgery either via an antral approach or with a lateral rhinotomy. In the 1970s, surgery was combined with ligature of the external carotid artery and, since 1981, it has been combined with preoperative embolization. Two patients received radiotherapy (45 Gy) as primary treatment and the 3 cases of multiple recurrence received radiotherapy (30-45 Gy) as secondary treatment. No recurrence was found in patients treated with radiotherapy. The overall recurrence rate was 25%; the recurrence rate in non-embolized patients was 8% and among embolized patients it was 41%. We found no statistically verified differences in recurrence rate between embolized and non-embolized patients. No statistically significant difference was found in either recurrence or peroperative bleeding when comparing preoperatively embolized patients with non-embolized ...
