中文摘要：
目的探讨神经内镜治疗脑脊液鼻漏的特点和手术中的操作体会，以利于提高治愈率，减少并发症。方法回顾性分析该院用神经内镜治疗的11例脑脊液鼻漏患者，其中外伤性者3例，医源性者8例。11例患者均进行了MRI检查，3例外伤患者中显示瘘口者2例。瘘口大小O．2～1．2cm，小于0．5cm瘘口采用黏膜和明胶海绵填塞的方法，0．5～1．2cm的瘘口采用填塞黏膜、明胶海绵和人工硬膜的方法。结果首次手术成功9例，1例再次手术成功，1例再次内镜手术仍未成功，第3次采取经颅手术获得成功。单纯内镜手术没有并发癫痫等，1例患者出现颅内感染。结论神经内镜治疗脑脊液鼻漏是一项有效而简单快捷的方法，具有良好视野和微侵袭的优点。小漏口仅用黏膜和明胶海绵修补即可，漏口大时用人工硬膜修补加全窦填塞效果更佳。
英文摘要：
[ Objective ] To explore the features of treating eerebrospinal fluid rhinorrhea with endoseopic tech- nique and the experience of operation, for improving the cure rate and reducing the complication. [Method] Retro- spective analysis of 11 patients （3 traumatic, 8 iatrogenic） treated with transnasal endoscopic. All of them acceptted MR/, and 2 patients showed orificium of the fistulae in 3 traumatic patients. The diameter of these fistulaes were dif- ferent from 0.2 centimeter to 1.2 centimeter. We used fasciae and gelatin sponge to repair leak for the fistulae which diameter below 0.5 cm, and used fasciae, gelatin sponge and artifieial-dura for the fistulae which diameter 0.5-1.2 em. [ Results ] In 11 cases of eerebrospinal fluid rhinorrhea, 9 cases were successful after the first operation, one case needed to be repaired once more. Only one needed to be repair at the third time, operated with external nasal surgery. Simply endoscopic surgery didn＇t accompany with epilepsy, and so on, one case appeared intracranial infec- tion after surgery. [ Conclusion ] Transnasal endoscopic repair technique is effective, simple and swift, and is pro- vided with merits of good eyesight and minimally invasive. It is feasible that the small leak was repaired with fasciae and gelatin sponge. The effect is much better if we use artificial-dura to repair and wad the sphenoidalis sinus com- pletely when the orificium fistulae is large.
