Abstract：
This study aimed to investigate the efficacy and safety of canalicular laceration repair using a novel bicanalicular silicone tube.
Retrospective and consecutive patients who underwent canalicular laceration repair using novel Runshi-RS bicanalicular silicone stents from January 2020 to February 2021 were included. The stent was placed for 3 months, and patients were followed up for more than 3 months after extubation. Demographics, causes of eyelid injuries, placement time and position of stent, and surgical outcomes at follow-up were recorded. Anatomical success was evaluated by diagnostic probing and irrigation of lacrimal passage, while functional success was evaluated by the patient\'s subjective symptoms of epiphora.
This study included 43 patients with canalicular laceration. The median age was 43 years (3-75 years). The average duration of stent implantation was 12.9 weeks, and the follow-up time was 8.8 months. No complications were observed in any patients during operation and follow-up. After extubation, irrigation of the lacrimal passage in 43 eyes showed no obstruction, and the anatomical success rate was 100%. Overall, 39 patients (90.7%) had no subjective symptoms of epiphora. All patients got good cosmetic results. Furthermore, subgroup classification showed deep laceration group (distance from laceration to punctum>5 mm) accounted for 51.2%, and the functional success rate of the deep laceration group was lower than that of the shallow laceration group.
Runshi-RS bicanalicular silicone stent achieved good anatomical (100%) as well as functional (90.7%) success and good cosmetic results (100%) in patients with canalicular laceration repair.

摘要：
本研究旨在探讨使用新型双管硅胶管修复泪小管裂伤的有效性和安全性。
纳入了2020年1月至2021年2月使用新型Runshi-RS双管硅胶支架进行泪小管断裂修复的回顾性和连续患者。支架放置3个月，术后随访3个月以上。人口统计,眼睑受伤的原因,支架的放置时间和位置，并记录随访时的手术结果.通过诊断探查和冲洗泪道来评估解剖成功。而功能的成功是通过患者的顿唇主观症状来评估的。
本研究包括43例泪小管断裂患者。中位年龄为43岁（3-75岁）。支架植入术的平均时间为12.9周，随访时间为8.8个月。所有患者在手术和随访期间均未观察到并发症。拔管后,43只眼的泪道冲洗没有阻塞，解剖成功率为100%。总的来说,39例(90.7%)患者均无顿流主观症状。所有患者均获得良好的美容效果。此外，亚组分类显示深度裂伤组(裂伤至点距离>5mm)占51.2%,深裂伤组的功能成功率低于浅裂伤组。
Runshi-RS双管硅胶支架在泪小管裂伤修复患者中取得了良好的解剖（100％）和功能（90.7％）的成功和良好的美容效果（100％）。
