Embolization of a juvenile angiofibroma (JNA) is commonly performed prior to surgical resection. Traditionally, it has been performed from an intra-arterial approach with particulate material. A novel technique is described in which a JNA was completely devascularized prior to surgical removal by direct percutaneous embolization with only ethylene vinyl alcohol. A midfacial degloving and medial maxillectomy/maxillotomy was then performed and the tumor extirpated with blunt finger dissection and the assistance of an endoscope, with 200 ml of blood loss.
青少年血管纤维瘤（JNA）通常在手术切除前进行栓塞。传统上，它是通过动脉内途径用颗粒物质进行的。本文描述了一种新的技术，通过直接经皮栓塞用乙烯-乙烯醇完全使 JNA 血管化，然后在手术切除前进行。然后进行中面部皮瓣剥离和内侧上颌骨切除术/上颌切开术，并用钝手指解剖和内窥镜协助切除肿瘤，失血 200ml。
