方法：选用0.3mm×0.6mm直径的医用硅胶管治疗24例新鲜泪小管断裂患者，并与同期采用硬外麻管治疗方式治疗24例进行比较，平均随访1.5a。

结果：改良支撑方式术后硅胶管稳定性好，随访期间泪道通畅，排泪正常； 常规支撑法拔管前术眼有不同的刺激症状，有异物感，流泪，充血，分泌物多，影响外观，两组并发症发生率分别为4.2%(1/24)及33.3%(8/24)，有显著性差异(P<0.01)； 拔管后随访期两组治愈率分别为91.7%(22/24)及62.5%(15/24)，比较有显著性差异(P<0.01)。

结论：改良硅胶支撑管方式在泪小管断裂修复术有较好的效果，该法疗效确切，患者易于接受，是一种新的有效方法。

METHODS:Silicon tube of 0.3mm×0.6mm in diameter was used to treat 24 patients with newly occurred lacrimal canaliculi rupture. Other 24 patients treated with regular tube were served as control. The mean follow-up was 1.5 years.

RESULTS:Patients treated with modified tube showed good stability. During follow-up, lacrimal passage was clear and tear drainage maintained unobstructed. In control group, irritation occurred before tube drawing, e.g. foreign body sensation, lachrymation, hyperemia, excessive exudates. The rate of complication between modified treatment group and control group was 4.2%(1/24)and 33.3%(8/24), respectively. The difference was statistically significant(P<0.01). The cure rate between the two groups was 91.7%(22/24)and 62.5%(15/24), respectively, after tube drawing(P<0.05).

CONCLUSION: Treatment ofcanalicular laceration using modified silicon tube shows good efficacy, favorable patient compliance, thus can be a new effective treatment.
