硬膜外导管支撑下泪小管断端吻合手术38例

Clinical analysis of canaliculoplasty supported by epidural tube in 38 cases

目的:探讨以硬膜外导管为断端支撑物行下泪小管吻合术的疗效。方法:在表面麻醉和局部麻醉下对38例38眼下泪小管断裂患者行显微镜下寻找鼻侧断端,置入硬膜外导管后作下泪小管断端吻合术并留管3mo。结果:在38例患者中成功34例,其余4例因术中未找到泪小管鼻侧断端而失败。结论:以硬膜外导管作为断端支撑物行下泪小管吻合术,关键是寻找断端,该方法简便,手术成功率高。

AIM：To summarize the experience of canaliculoplasty supported by epidural tube. METHODS：Thirty-eight cases （38 eyes） of laceration of lacrimal canaliculus were treated by canaliculoplasty.The hurt nasal side on the lacrimal canaliculus was found under operation microscope.The epidural tube was implanted in lacrimal passage as a temporary internal stand,and kept for 3 months. RESULTS：The operation was successful in 34 cases and failed in 4 cases because the nasal dacryocanalicular remainder was not found. CONCLUSION：The key of the operation is to find the dacryocanalicular remainder. This method is simple with high success rate.
