AIM:To disscus the clinical effect of the silicone tube implantation under the guidance of memory wire in the treatment of lacrimal canaliculus. METHODS:One hundred and fifteen cases (115 eyes ) of traumatic canalicular laceration were treated by canaliculoplasty from September 2012 to June 2014. Finding the end of lacrimal canaliculus under microscope, guided by memory wire which was probed in lacrimal passage to the nasal cavity, intubating double-passage silicone tube as a support and end-to-end anastomosis. The condition of epiphora and irrigation of lacrimal passage were observed after extubation. RESULTS: All 115 cases were experienced successful operation. All patients were followed up for 6mo ~ 1a (mean 9. 3mo) after extubation. Lacrimal passage was unobstructed in 96 cases 96 eyes(83. 5%), stricture in 13 cases 13 eyes (11. 3%), and blocked in 6 cases 6 eyes (5. 2%). CONCLUSION:Double-passage silicone tube guided by memory wire may be an optional technique in the treatment of traumatic lacrimal duct laceration, which is a feasible, minimally - invasive, safe and effective method.%目的：探讨记忆钢丝引导下双环硅胶管治疗泪小管断裂的临床疗效。 方法：回顾性分析2012-09/2014-06收治的115例115眼外伤性下泪小管断裂患者的资料。显微镜下找到泪小管断端,泪道探通后,在记忆钢丝引导下置入硅胶管作为支撑物,行泪小管断端吻合术,并将双环硅胶管在鼻腔内打结。 结果：患者115例115眼均完成手术,术后随访6mo~1a,其中泪小管通畅96例96眼(83.5%),泪小管狭窄13例13眼(11.3%),泪小管阻塞6例6眼(5.2%)。 结论：记忆钢丝引导下双环硅胶管治疗泪小管断裂是安全有效的,临床效果满意,具有成本低、操作简单、恢复快的优点,值得推广。
