由于经上颌窦颌内动脉结扎及经皮栓塞颌内动脉远支治疗顽固性鼻后部出血不一定都能取得成功，故考虑采用替代技术。该作者利用内窥镜技术和器械的进步和几乎恒定的解剖形态，采用鼻内窥镜颌内动脉终末支结扎治疗顽固性鼻后部出血取得成功，且未发生并发症。从１９９３年３月～ As the maxillary sinus ligation and percutaneous ligation of the maxillary internal carotid artery refractory intra-posterior nasal hemorrhage may not be able to succeed, so consider the use of alternative technologies. Using endoscopic techniques and instrumental advances and almost constant anatomy, the author succeeded in the treatment of refractory posterior nasal hemorrhage using endoscopic ligation of the endosuperior branch of the internal carotid artery with no complications. From March 1993 ~
