目的:探讨外伤性泪小管断裂吻合术失败原因,提高泪小管吻合术的成功率。方法:回顾68例泪小管断裂的病例,显微镜下寻找断端,硬膜外管做支撑物,吻合后分析预后。结果:9例患者导管脱出再次插入;5例患者吻合口撕脱分离再次吻合;12例上睑固定线松脱再次缝合。结论:多种原因可导致泪小管吻合术失败,术中注意可能引起泪小管吻合失败的原因,可以减少手术后多个问题的出现。
Objective: To investigate the failure causes of anastomosis of traumatic canalicular laceration and improve the success rate of lacrimal duct anastomosis. Methods: A retrospective analysis of 68 cases of canalicular rupture, looking for a broken end under the microscope, epidural tube as a support, anastomosis and analysis of prognosis. Results: The catheterization of 9 patients was inserted again. The anastomotic avulsion of 5 patients was separated and re-anastomosed. Twelve cases of upper eyelid fixation line were sutured again. Conclusion: A variety of reasons can lead to failed lacrimal canal anastomosis. The intraoperative attention may cause the failure of lacrimal canal anastomosis, which can reduce the occurrence of multiple problems after operation.
