探讨小儿先天性泪囊炎方便、有效的治疗方法及泪道探通术的治疗时机。 方法：对52例65眼小儿先天性泪囊炎按月龄分为3组，每组均在表面麻醉下用一次性泪道冲冼针头行泪道冲冼，然后直接进行泪道探通术。 结果：月龄1~3mo组27例32眼，一次探通治愈30眼（94%）；4~6mo组13例20眼，一次探通治愈16眼（80%）；7~11mo组12例13眼，一次探通治愈6眼（46%）。 结论：使用一次性无菌冲洗针行泪道探通术是治疗婴幼儿泪囊炎的一种有效、安全、简便的方法

To investigate a convenient and effective treatment for congenital dacryocystitis and the timing of probing lacrimal passage. METHODS:Totally 52 cases (65 eyes) were collected in our study and classified into 3 groups according to their ages. Lacrimal passage flushing was done for each case by using a disposable sterile flushing needle under topical anesthesia, then the lacrimal passage was probed using the same needle directly. RESULTS:Thirty eyes (94%) were cured by probing the lacrimal passage once in the 1-3 months group which included 27 cases (32 eyes). 16 eyes (80%) were cured by probing once in the 4-6 months group which included 13 cases (20 eyes). The cure rate in the 7-11 months group by probing the lacrimal passage once was 46%. CONCLUSION:Lacrimal passage probing by a disposable sterile flushing needle is an effective, safe and convenient method for treating infantile dacryocystitis.
