Abstract: Objective To observe the clinical effect of the treatment of traumatic lacrimal canalicular laceration with single canalicular artificial lacrimal duct and double canalicular artificial lacrimal duct. Methods Sixty patients (60 eyes) with lacrimal canalicular laceration who visited the Department of Ophthalmology, Affiliated Hospital of Chengde Medical University the first time from March 2017 to December 2021 were selected. According to different surgical methods, patients were divided into group A(27 patients )and group B(33 patients). Group A was treated with single canalicular placement of artificial lacrimal duct for canalicular laceration anastomosis, and group B was treated with double canalicular placement of artificial lacrimal duct for canalicular laceration anastomosis. After 6 months ,we compared the patency of lacrimal passage and complications between the two groups. Results The cure rate of group A was 48.15%(13/27) and that of group B was 81.82%(27/33). There was significant difference between the two groups (P<0.05). Conclusion The treatment of lower lacrimal canalicular laceration with double canaliculi implantation artificial lacrimal duct is effective, the reduction of lacrimal canaliculi is closer to the anatomical structure, and there are few complications. It is an ideal surgical method for the treatment of traumatic lower lacrimal canalicular laceration.

Key words: lacrimal canalicular laceration, lacrimal canalicular laceration anastomosis, single canalicular placement artificial lacrimal duct, double canalicular placement artificial lacrimal duct

摘要： 目的 观察应用单泪小管置入式人工泪管与双泪小管置入式人工泪管对外伤性下泪小管断裂治疗的临床疗效。方法 选取2017年3月~2021年12月首次就诊于承德医学院附属医院眼科的60例（60眼）下泪小管断裂的患者,根据手术方式的不同将60例患者分为A、B 2组,其中,A组共27例患者,B组共33例患者。A组采用单泪小管置入式人工泪管进行泪小管断裂吻合术治疗,B组采用双泪小管置入式人工泪管进行泪小管断裂吻合术治疗。比较2组患者术后6个月的泪道通畅情况及并发症情况。结果 A组治愈率为48.15%（13/27）,B组治愈率为81.82%（27/33）,组间比较差异有统计学意义（P<0.05）。结论 采用双泪小管置入式人工泪管治疗下泪小管断裂手术疗效佳,泪小管复位更接近解剖结构,并发症少,是治疗外伤下泪小管断裂的一种理想的手术方式。
