Diagnosis and treatment for tumor with hypervascularity in the sinonasal and epipharyngeal regions

Abstract

Surgical procedures for tumor with high vascularity in the head and neck regions is complicated by massive hemorrhage. Superselective embolization method has widely been accepted as the first choice to controle hemorrhage during operation of vascular tumors. This method was apllied for sinonasal hemangioma and epipharygeal angiofibroma preopera-tively. The hemorrhage during the operations was 5 to 1200ml in these cases. The superselective embolization was found to be effective in our series.
