目的:探讨≥40岁鼻出血患者的常见鼻出血部位。方法:表面麻醉下行鼻内镜检查,查找出血部位。结果:69例接受了鼻内镜检查,出血位于下鼻道穹窿顶17例,鼻底1例,中甲前端对应中隔部位包括嗅裂前段鼻顶17例,中鼻甲下缘1/2处1例,中鼻道后端3例,利特尔区2例,即查到出血部位的共41例占59%(41/69)。未查到出血部位的28例,占41%(28/69)。结论:≥40岁鼻出血患者的鼻出血部位并不是吴氏鼻鼻咽静脉丛和鼻中隔后部动脉,而是来自下鼻道穹窿顶的颌外动脉分支和中鼻甲对应的鼻中隔及嗅裂前段的鼻顶等部位的筛前动脉出血。
Objective: To investigate the common nosebleed site of patients with nosebleed over 40 years old. Methods: Surgical endoscopic nasal endoscopy, find the bleeding site. RESULTS: Sixty-nine patients underwent nasal endoscopy. Bleeding was located in 17 cases of the inferior nasal dome and 1 case of the nasal floor. The anteroposterior part of the middle part consisted of 17 cases of the anterior nasal crest of olfactory fissure and 1/2 of the inferior border of the middle turbinate 1 case, 3 cases of posterior end of middle meatus, and 2 cases of litle area, that is, 41 cases (59/41) were found bleeding sites. No bleeding sites were found in 28 cases, accounting for 41% (28/69). Conclusion: The epistaxis site of patients with nasal bleeding more than 40 years old is not the nasopharyngeal venous plexus and the posterior nasal septum artery, but the extracranial artery branches from the inferior nasal dome and the nasal septum corresponding to the middle turbinate and the anterior segment The top of the nose and other parts of the anterior ethmoidal hemorrhage.
