方法：回顾性分析我院2014-01/2015-12收治的儿童泪小管断裂患者42例42眼。根据入院时间顺序分为两组，单路泪道留置硅胶管组20例20眼，环形留置硅胶支撑管组22例22眼，对比分析两组患者的治疗效果。

结果：术后2wk～1mo，单路泪道留置硅胶管组有4眼患者由于护理不当，不慎将硅胶管脱落，再次手术处理。环形留置硅胶管组患者无硅胶管脱落者，两组比较差异有统计学意义(P<0.05)。单路泪道留置硅胶管组中，治愈16眼，好转1眼，无效3眼，均为术后2wk～1mo硅胶管脱落患者(1眼为犬咬伤患者，2 眼为放炮炸伤患者)，治疗有效率为85%。环形留置硅胶管组中，治愈20眼，好转2眼，治疗有效率为100%。两组患者治疗有效率比较，差异有统计学意义(P<0.05)。

结论：儿童泪小管断裂需及时手术治疗，合理的手术治疗多能获得较好的手术效果，采用环形留置硅胶管较单路泪道留置硅胶管稳定性好，并发症少，临床治疗效果好。

METHODS: A retrospective analysis from January 2014 to December 2015 were taken. According to admission time sequence, 42 children with lacrimal canaliculi rupture was divided into two groups. One group was treated with single silicone tube insertion, the other was treated with annular silicone tuber insertion. The treatment results were comparatively analyzed.

RESULTS: There were 4 eyes in single silicone tube group occurred fall off in 2wk to 1mo after operations because of improper nursing and the second operations were taken. There was no eye with this in annular silicone tuber groups, the difference between the two groups was significant(P<0.05). In single silicone tube group, 16 eyes were cured, 1 eye improved, 3 eyes unchanged which were the 3 eyes with fall off. Those 3 eyes were 1 patient bitten by dog, 2 bombed; the effective rate was 85%. In annular silicone tuber insertion, 20 eyes were cured, 2 eyes improved and the effective rate was 100%, the difference between the two groups was significant(P<0.05).

CONCLUSION: Children's lacrimal canaliculi rupture should be timely given surgical treatment, reasonable surgical treatment can achieve good operation effect. Annular silicone tube has good stability, fewer complications than single silicone tube, and clinical treatment effect is good.
