Endoscopic endonasal transmaxillary ligation of a feeding artery and coblation plasma technology enables en bloc resection of advanced juvenile nasopharyngeal angiofibroma without preoperative embolization

Juvenile nasopharyngeal angiofibroma (JNA) is a hypervascular tumor and uncontrolled hemorrhage makes its removal very difficult. Although preoperative intravascular embolization of a feeding artery is recommended, serious complications such as iatrogenic thrombosis in the brain and insufficient decrease in blood flow to the tumor are concerns. Recently, coblation plasma technology has been reported to be useful for tumor removal with minimum hemorrhage under a clear surgical field. Here we report successful removal of advanced JNA without preoperative embolization, using intraoperative ligation of the maxillary artery and coblation plasma technology.
