Two cases of nasopharyngeal angiofibroma--effect of preoperative transarterial embolization.

ABSTRACT

Recently, two cases of nasopharyngeal angiofibroma were experienced. We emphasized in this paper that polytomography, computed tomography scan and angiography are necessary for preoperative evaluation of locating the lesion and delineating the vascular supply. An important problem in surgical treatment is massive bleeding, and the transarterial embolization is helpful to diminish it.
