泪小管断裂40例临床分析

Clinical analysis on canalicular laceration in 40 cases

目的探讨泪小管置管方式及其义管选择对泪小管吻合术疗效的影响。方法根据泪小管断端情况选择手术方法,分别采用输尿管、硬膜外麻醉导管或硅胶管治疗泪小管断裂40例,随访3个月以上。结果环形泪道置管法有效率为96.77%,U型泪道置管法有效率为88.89%。不同导管各组治愈率比较,差异均无统计学意义(P>0.05)。结论泪小管吻合术中采用U型泪道置管法或环形泪道置管法,在泪道内植入输尿管导管、硬膜外麻醉导管或硅胶管的疗效相当,均为治疗泪小管断裂的有效方法。

Objective To explore effect of lacrimal canaliculus cathetering method and artificial tube on curative effect of anastomosis of broken lachrymal canaliculus. Methods 40 patients with canalicular laceration were respectively given ureter, segmental epidural catheter and silicone tube for treatment according to canalicular laceration status. And the follow up was more than 3 months. Results Effective rates of annular lacrimal passage intubation method and U-shaped lacrimal passage cathetering method were 96.77% and 88.89% respectively. Difference in cure rate of different catheters in every group was no significant（P 〉 0.05）. Conclusion In anastomosis of broken lachrymal canaliculus, curative effects of U-shaped lacrimal passage cathetering method and annular lacrimal passage intubation method are equal to those of ureteral catheter, segmental epidural catheter and silicone tube implanted in lacrimal passage. They were all effective methods in treatment of canalicular laceration.
