Title: Endoscopic endonasal transmaxillary ligation of a feeding artery and coblation plasma technology enables en bloc resection of advanced juvenile nasopharyngeal angiofibroma without preoperative embolization
Abstract: 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. The left nasal cavity of a 23-years-old man was closed by a JNA tumor at Radkowski stage IIC, which was 65 mm in size and extended from the nasal cavity to the infratemporal fossa. MRA imaging showed the maxillary artery running along the posterior wall of the maxillary sinus. Therefore, the maxillary artery was first clipped using an endoscopic modified medial maxillectomy (EMMM) approach and endoscopic endonasal en bloc resection of the tumor was then completed using coblation technology with no need for blood transfusion. This case illustrates that preoperative embolization is dispensable in JNA surgery even at Stage IIC if the maxillary artery can be ligated during surgery and a coblation device can be utilized.
