目的 为延长泪道插管留置时间 ,提高下泪小管断裂吻合术的成功率。方法 以自制泪道插管固定器固定泪道插管 ,术后 2月拔管。结果 泪道插管留置时间 :固定器组 ( 6 9 72± 9 10 )天 ,对照组 ( 4 3 88± 19 2 7)天 ,固定器组留置时间显著长于对照组 (u =7.5 7,P <0 0 1)。拔管后 3月泪道冲洗通畅者 :固定器组泪 36例中 31例 ( 86 11% ) ,对照组 32例中 18例( 5 6 2 5 % ) ,固定器组通畅率显著高于对照组 ( χ2 =7.5 0 ,P <0 0 1)。结论 泪道插管留置时间越长 ,手术效果越好。影响留置时间的主要因素为泪道外插管和固定物影响美观、磨擦眼球和脱管。本方法可延长留置时间 。
Objective To prolong the stents left times and improve success rate in managing canalicular lacerations.Methods A fix instrument made by ourselves was used to fix canalicular intubation tube in 36 eyes.Stents were left in place for 2 months postoperatively and then removed.Irrigation through the canaliculus was performed 3 months after stents removal.Results The average stents left times were 69.72±9.10 days in the stents fixed with instruments group and 43.88±17.29 days in the control group.Irrigation showed canalicular patency in 31 of 36 patients in the stents fixed group and 18 o f 32 patients in the control group.There were statistically significant difference between the two groups in the stents left times(u=7.57,P<0.01) and in the success rate (x 2=7.50,P<0.01).Conclusion The stents left times is the longer,the success rates is higher in managing canalicular lacerations.The stents left times may be shortened by the stents influencing cosmesis,rubbing eyeball and drawn out of canaliculus.Fixing stents with this technique appears to be a reliable new method to prolong the stents left times and have high success rate in managing canalicular lacerations.
