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 To observe the clinical effect of lacrimal duct rupture anastomosis under microscope. Methods Under the operation microscope, we directly looked for the broken end of the lacrimal canalis near the dacryocystorhinus and used the spinal cannula as the endoluminal support to coincide with the ruptured lacrimal canaliculus. Looking for tears under the operating microscope, Small tube off the nasal side of the stump to epidural anesthesia catheter as canalicular support, anastomosis lacrimal duct stump. Results All the 29 patients were followed up for more than one year, 21 cases were cured, 5 cases had overflowing of tears due to small spot of valgus, and 3 cases were unhealed due to scar formation. Conclusions Under surgical microscope, we can directly look for the end of lacrimal duct near the lacrimal sac. The successful rate is high. The anastomosis is performed with spinal anesthesia as the support, and lacrimal duct function is recovered after operation. The curative effect is good.
