对于顽固性后鼻道鼻衄最有效治疗方法为结扎患侧上颌动脉。我科自1991年应用银夹行上颌动脉夹闭治疗顽固性鼻衄5例,现报告如下。 1 临床资料 5例中男3例,女2例,年龄22～43岁。其中4例为后鼻孔下部出血,出血点不清;1例为上颌Lefort Ⅰ型截骨术后。5例均经多次、前后鼻腔填塞法止血无效,其中2例行患侧颈外动脉结扎无效。 2 方法和效果病人仰卧位,常规行上颌窦根治术式,窦前壁骨窗尽量扩大,便于夹闭动脉时操作。吸出窦内分泌物,剥离并切除窦后壁粘膜。依窦发育情况,再开后壁骨窗,一般偏内侧,约为3.0cm×2.5cm。取出骨壁后,在手术显微镜下观 The most effective treatment for intractable posterior nasal rhinoplasty is to ligate the affected maxillary artery. Our department since 1991, silver clip line maxillary artery occlusion in the treatment of refractory epistaxis in 5 cases, are as follows. A clinical data of 5 cases, 3 males and 2 females, aged 22 to 43 years old. In 4 cases, the posterior nostril hemorrhage and bleeding were not clear. One case was maxillary Lefort Ⅰ osteotomy. 5 cases were repeated many times, before and after the nasal packing method to stop bleeding, including 2 cases of ipsilateral carotid artery ligation invalid. 2 methods and effects of supine patients, conventional maxillary sinus radical mastectomy, anterior sinus wall to maximize the window to facilitate the operation of the artery clamping. Aspiration of sinus secretions, dissection and removal of sinus mucosa. According to sinus development, and then open the posterior wall bone window, generally partial medial, about 3.0cm × 2.5cm. Remove the bone wall, under the microscope view
