目的：探讨显微镜下泪小管断裂吻合联合环形管置入术的手术效果。

方法：回顾性分析2018-06/12期间于我院就诊的下泪小管断裂患者59例59眼，在显微镜下找到泪小管断端，置入环形管作为支撑物，术后3mo拔管后随访3mo，观察手术疗效及并发症情况。

结果：所有患者均在显微镜下顺利找到泪小管鼻侧断端并成功置环形管，术后第6mo复诊，治愈46例46眼，好转5例5眼，无效8例8眼，总有效率86%(51/59)，术后未见严重的相关并发症及眼睑畸形。

结论：显微镜下泪小管断裂吻合术是治疗泪小管断裂的有效手术方式。

METHODS: A retrospective study was conducted on 59 cases(59 eyes)from June 2018 to December 2018 with lower lacrimal canalicular laceration. The nasal cut end of lacerated lacrimal canaliculi was found under the microscope, the circular tube was implanted as a support. The tube was removed 3mo after the surgery. All the patients were followed additional 3mo. The therapeutic effect and complications were observed.

RESULTS: All patients were successfully operated. 46 cases(46 eyes)were cured, 5 cases(5 eyes)were improved, 8 cases(8 eyes)had no effect. The overall successful rate was 86%(51/59). No serious complications and eyelid deformity were found.

CONCLUSION: The anastomosis surgery combined with circular tube implantation is an effective treatment for the lacrimal canaliculi laceration.
