目的：探讨双路泪道留置引线硅胶管治疗外伤性下泪小管断裂的应用及效果。 方法：回顾性病例研究。2008-10/2011-09我院收治32例32眼外伤性下泪小管断裂患者，采用双路泪道留置硅胶管，主要评价拔管6mo后泪道冲洗通畅情况。 结果：拔管6mo后治疗有效率为29例（91%），而治疗无效3例(9%)。 结论：采用双路泪道留置硅胶管植入术治疗外伤性下泪小管断裂，术后外观及疗效满意，易于被患者接受，值得临床推广。

AIM:To investigate the application of double-passage silicone tube in the treatment of traumatic inferior lacrimal duct laceration. METHODS:Thirty-two cases (32 eyes)of traumatic inferior canalicular laceration were treated by canaliculoplasty from October 2008 to September 2011. All cases were performed with silicone tube double-passage annular canalicular intubation.The condition of epiphora and irrigation of lacrimal passage were observed after 6 months extubation continuously. RESUITS:The 32 cases were followed up in 6 months after extubation, the treatment was effective in 29 cases (91%)，3 cases (9%) showed no effect. CONCLUSION:The effect of double-passage silicone tube in the treatment of traumatic inferior lacrimal duct laceration is satisfactory. This method can be easily accepted by patients and worthy of clinic application.
