Abstract
Five patients with juvenile nasopharyngeal angiofibroma were found between 1984 and 1990 in our department. Clinical findings, treatment, and postoperative follow-up were reported. Two patients belonged to stage III and remnant 3 patients belonged to stage I. In cases of stage I, a surgical approach through the suprahyoid pharyngotomy was a worthy procedure to try, because angiofibroma was observed under direct vision and hemostasis was easy. In therapeutic planning, the authors emphasized the need of a preoperative staging classification based on CT scanning and selective angiography. In immunohistochemical studies, Langerhans cells with S-100 protein positive were found. Fibroblasts revealed estradiol positive but testosterone showed negative in all cases. Thus, juvenile nasopharyngeal angiofibroma was considered to be neoplasm related estradiol.
