目的：探讨鼻内镜下激光泪囊鼻腔造口置管术治疗慢性泪囊炎的临床疗效。

方法：选取2014-01/2016-06住院治疗的30例32眼慢性泪囊炎患者，均在鼻内镜下行激光泪囊鼻腔造口术，术中联合应用丝裂霉素C并留置硅胶引流管，术后常规6wk拔管，观察治疗效果。

结果：术后随访6～15mo。慢性泪囊炎30例32眼中，治愈28眼(88%)，好转3眼(9%)，无效1眼(3%)，总有效率97%。

结论：鼻内镜下泪囊鼻腔激光造口置管术治疗慢性泪囊炎安全有效。

METHODS:Totally 30 cases(32 eyes)of chronic dacryocystitis were selected between January 2014 to June 2016, all of them were treated with laser-assisted endoscopic dacryocystorhinostomy combined with mitomycin C and stent intubation. The stent was moved at 6wk after surgery in generally. The clinical effect was observed.

RESULTS: After 6-15mo of follow-up, 28 eyes were cured(88%), 3 eyes were improved(9%), and 1 eye was ineffective(3%). The total effective rate was 97%.

CONCLUSION: Laser-assisted endoscopic dacryocystorhinostomy with stent intubation is effective and safe in the treatment of chronic dacryocystitis.
