显微镜下泪小管断裂吻合术的临床观察

目的观察显微镜下行泪小管断裂吻合置管术的临床效果。方法在手术显微镜下直接寻找泪小管断离近泪囊侧断端,以腰麻管作为管腔内支撑物,吻合断裂的泪小管;在手术显微镜下沿泪小管断端在复原伤口后找泪小管断离鼻侧断端,以硬膜外麻醉导管作为泪小管内支撑,吻合泪小管断端。结果 29例患者随访均超过1年,21例治愈,5例因泪小点外翻出现溢泪为好转,3例因瘢痕形成不通为未愈。结论在手术显微镜下直接寻找泪小管近泪囊侧断端,成功率高,以腰麻管为支撑物行吻合术,术后恢复泪道功能,疗效较好。

Objective observed under the microscope of canalicular laceration of catheterization of clinical effect.Methods in operation under direct microscopic finding canaliculus breakage of lacrimal sac near the distal stump,with spinal anesthesia tube as the inner lumen supporter,broken lacrimal canaliculus anastomosis.the operation microscope along the canaliculus breakage in healing wounds after finding canaliculus broken from the nasal side end,with epidural anesthesia catheter as a lacrimal duct inner support,canaliculus.Results 29 patients were followed up for more than 1 years,21 cases were cured,5 cases with lacrimal punctum ectropion have epiphora improved,3 cases due to scar formation is not.Conclusion in the operation under direct microscopic finding canaliculus lacrimal sac near the distal stump,high success rate,with spinal anesthesia for supporting pipe line anastomosis of lacrimal function,postoperative recovery,Good effect.
