方法：选取2006-01/2013-01在我院门诊就诊的262例286眼经保守治疗2wk无效的新生儿泪囊炎患儿作为本次的观察对象； 按数字表法随机分为 A，B 两组，其中A组133例149眼从上泪小点进针行泪道探通，B组129例137眼从下泪小点进针行泪道探通，比较两种方法的治疗效果及并发症，并随访1mo。

结果：A组治愈率98.7%； B组治愈率93.4%； A组并发症发生率少于B组； 两组比较差异具有统计学意义(P<0.05)。

结论：从上泪小点进针行泪道探通术对新生儿泪囊炎的治疗效果优于从下泪小点进针行泪道探通术，且减少泪小管撕裂、假道及泪道继发性粘连等并发症的发生率。

METHODS: Totally, 262 cases(286 eyes)of neonatal dacryocystitis which failed in a two-week conservative treatment were selected from January 2006 to January 2013 in our outpatient department. They were randomly divided into Group A and Group B. Then, 133 cases(149 eyes)in Group A received lacrimal probing through upper lacrimal punctum, and 129 cases(137 eyes)in Group B received lacrimal probing through lower lacrimal punctum. The patients were followed up for one month and therapeutic effect and incidence of complications of the two methods were compared.

RESULTS: The cure rate of was 98.7% in Group A and 93.4% in Group B. The incidence of the complications in Group A was lower than that of Group B. The differences between the two groups were significant(P<0.05).

CONCLUSION: Lacrimal probing through upper lacrimal punctum in neonatal dacryocystitis is more effective than probing through lower lacrimal punctum,and it has a lower incidence of complications including lacrimal tear, false passage and secondary adhesion.
