目的 分析婴幼儿泪小管断裂吻合术的特点,比较硬膜外麻醉管与改良的硅胶支撑管在婴幼儿泪小管断裂修复的应用和治疗效果.方法 回顾自2009年12月至2015年12月期间,我院收治16例(16眼)外伤性泪小管断裂患儿,其中8例采用单路泪道留置硬膜外麻醉导管,8例采用单路泪道留置硅胶管,主要评价术后6个月时两组病例泪道冲洗通畅情况.结果 术后6个月时泪道冲洗不通畅者,硬膜外管3例(37.5%),硅胶管组无,差异具有显著统计学意义(P=0.028).结论 婴幼儿泪小管断裂修复术使用改良的硅胶支撑管治愈率高,并发症少.“,”Objective To study the effect and characteristics of lacrimal canaliculus anastomosis to infants and yong children,assess the results and complications of the two different surgical treatments for erconstruction of lacrimal system. Methods Review 16 cases (16 eyes)with cananlicular laceration as a result of trauma were involved in the study from 2009 to 2015.To reanastomosis of the severed canaliculi,8 cases received monocanalicular intubation with epidural catheter, while the other 8 cases received monocanalicular silicone intubation.We evaluated function of the lacrimal drainage system by irrigation after 6 moths postoperatively. Results Restenosis of the lacrimal drainage system occurred in 3 and 0 cases intubation with epidural catheter and moldified silicone intubation separately.The success rate of modified silicone intubationg was significantly higher than intubation with epidural catheter(P =0.028). Conclusions Treatment of canalicular laceration using modified silicine tube shows high cure rate, fewer complications.
