方法：对年龄满4月龄～5岁泪囊炎患儿75例86眼经泪囊按摩治疗1mo无效且行常规加压泪道冲洗不通畅者，在表面麻醉下用单侧孔钝头泪道探针行泪道探通术，术后隔日行泪道冲洗最少3次。

结果：一次探通痊愈84眼，第二次探通后痊愈2眼。全部病例无感染、假道或泪点撕裂等并发症，经过3mo随诊观察，86眼痊愈患儿无1例复发。

结论：表面麻醉下单侧孔钝头泪道探针治疗新生儿泪囊炎安全有效。

METHODS: Seventy-five children(86 eyes), among 4-month or 5-year-old, who had dacryocystisis, were treated by dacryocystitis massage for one month. But it was invalid. Then blocking lacrimal passages were flushed under conventional pressure. Later, unilateral hole blunt lacrimal probes was used to make lacrimal passages open under topical anesthesia. After operation, lacrimal passages were flushed three times every two days.

RESULTS:Eighty-four cases were cured and no recurrence with only once treatment. Two cases were cured with the second treatment. All cases were without infection and no complications as false passages and lacrimal points were appeared. After 3-month followed up, none of them was relapsed.

CONCLUSION:Using unilateral hole blunt lacrimal probe for neonatal dacryocystitis under topical anesthesia is effective.
