目的:分析影响泪小管吻合术疗效的危险因素。方法:回顾2000年～2003年间我院收治因外伤所致的泪小管断裂患者49例,将受伤至手术时间、泪小管断裂位置、泪小管断裂程度、治疗手段、带管时间与预后(并发症的发生率、治愈率)的关系进行分析。结果:受伤至手术时间、手术方法及带管时间,是影响泪小管吻合术预后的因素。结论:及早手术、提高手术技巧,尽量不用泪囊切开法寻找泪小管鼻侧断端,带管3月以上,可以提高泪小管吻合术的成功率,减少并发症。 Objective: To analyze the risk factors affecting the efficacy of lacrimal canal anastomosis. Methods: From 2000 to 2003, 49 cases of traumatic canaliculus caused by trauma were treated in our hospital from January 2000 to December 2003. The time between injury and operation, the location of canalicular rupture, the degree of canalicular rupture, the treatment, the time of tube placement and the prognosis The incidence of the cure rate) of the relationship analysis. Results: The time from injury to operation, operation method and time of tube insertion were the factors influencing the prognosis of canalicular anastomosis. Conclusion: As early as possible surgery, improve surgical skills, try not to look for lacrimal sac lacrimal canal nasal end of the stump, with more than 3 months, can improve the success rate of lacrimal canal anastomosis and reduce complications.
