硅胶管双路置管术治疗泪小管断裂的临床疗效

The clinical efficacy of double stent method with silicone tubes for the treatment of lacrimal canaliculus laceration

目的探讨硅胶管双路置管术治疗泪小管断裂的手术方法及其疗效。方法在手术显微镜下直接寻找配合注气法、注水法及探针引导法找到泪小管鼻侧断端，行硅胶泪道支撑管双路置管，减张吻合泪小管断端。结果泪小管断裂26例（26眼），术后23例泪道冲洗通畅，无溢泪；2例拔管后1周泪道冲洗时有狭窄，伴轻微溢泪；1例有溢泪症状，泪道冲洗不通畅。治愈23例（88．46％），好转2例（7．69％），无效1例（3．85％）。结论硅胶泪道支撑管双路置管术治疗泪小管断裂具有手术操作简单，损伤小，效果好，外观自然等优点。

Objective To investigate the efficacy of double stent intubation with silicone tubes for the treatment of lacrimal canaliculus laceration. Methods The lacrimal canaliculus rupture ends was found under the surgical microscope by the methods of direct search, gas injection, water injection and the probe guiding. All cases received the silicone stent into the nasolacrimal duct through the double path. The anastomosis lacrimal canaliculus ends were sew up reduced tension. Results Twenty-six eyes of 26 cases with lacrimal canaliculus laceration underwent the surgery. The symptom of epiphora disappeared and lacrimal irrigation unobstructed in 23 cases. Two cases occurred narrow lacrimal when it was irrigated in 1 week after extubation, with mild epiphora. The symptom of epiphora, and obstructed lacrimal irrigation happened in 1 case. Twenty-three cases （88.46%） were cured completely, 2 cases （7.69%） were improved, 1 case was invalid （3.85%）. Conclusion The surgery of double canalicular stent method with silicone tube for the lacrimal canaliculus laceration is simple and little damage.
