目的：观察泪道内窥镜下泪小管切开联合新型R-S管置入治疗泪小管炎的临床疗效。

方法：泪道内窥镜下泪小管切开联合泪道置管术治疗泪小管炎患者31例32眼，置入新型R-S管15例15眼为A组，置入环形泪道引流管16例17眼为B组，所有患者均术后2～3mo拔管并观察至术后1a，比较两组手术疗效、手术置管时间、术后并发症、术后鼻腔异物感和鼻腔分泌物增多发生率。

结果：A组治疗有效率为93%，B组为94%，两组无差异(P>0.05)。A组置管时间为2.27±1.335min，B组为5.29±1.404min； A组术后并发症发生率为7%，B组为47%； A组术后鼻腔异物感发生率为7%，B组为41%； A组术后鼻腔分泌物增多发生率为0，B组为29%。手术置管时间、术后并发症、鼻腔异物感及鼻腔分泌物增多发生率均有差异(P<0.05)。

结论：泪道内窥镜下泪小管切开联合新型R-S管置入治疗泪小管炎效果良好，且新型R-S管具有操作简便、术后并发症少和患者舒适度高等优点。

METHODS: Thirty-one patients(thirty-two eyes)diagnosed as canaliculitis were investigated from July 2016 to September 2019 in our department. All patients have treated with canaliculotomy joint lacrimal tube implantation under lacrimal endoscope. The patients were randomly divided into two groups. Group A was treated with novel R-S lacrimal tube for 15 cases 15 eyes, and group B was treated with annular silicone tube. They were removed the lacrimal tube after 2-3mo, and followed postoperatively for at least 1a. The treatment results were comparatively analyzed.

RESULTS: The effective rate was 93% in group A and 94% in group B(P>0.05). The mean time of lacrimal tube implantation of group A was 2.27±1.335min, and group B was 5.29±1.404min. The total rate of complications was 7% in group A and 47% in group B. The rate of foreign body sensation in nasal cavity was 7% in group A and 41% in group B. The rate of increased nasal secretions was 0 in group A and 29% in group B. The difference of the mean time of lacrimal tube implantation, the rate of complications, the rate of foreign body sensation in nasal cavity and the rate of increased nasal secretions between two groups was statistically significant(P<0.05).

CONCLUSION: Canaliculotomy joint novel R-S lacrimal tube implantation under lacrimal endoscope is an effective way. The novel R-S lacrimal tube has the advantages of simple operation, less postoperative complications and high patient comfort.
