泪道激光及置管治疗复发性鼻泪管阻塞的研究

Laser combined with intubation for recurrent nasolacrimal duct obstruction

目的研究磷酸钛氧钾（KTP）泪道激光联合泪道置管对复发性鼻泪管阻塞的治疗效果。方法对门诊复发性鼻泪管阻塞54例（75眼）的治疗结果进行回顾性分析，根据是否选择置管，分为置管组（A组）24例（35眼）和非置管组（B组）30例（40眼）两组。结果术后A组成功率为45．71％，B组成功率为15．0％，两组比较差异有统计学意义（X2=8．495，P=0．005）。结论对于复发性泪道阻塞予以再次激光且联合泪道置管术有一定疗效，改善了溢泪情况。

Objective To investigate the clinical efficacy of KTP laser combined with intubation for recurrent nasolacrimal duct obstruction. Methods This medical records of 75 eyes of 54 patients with re- current nasolacrimal duct obstruction were retrospectively reviewed. All cases were divided into two groups. Group A （35 eyes of 24 cases） was treated by KTP laser combined with intubation. Group B （40 eyes of 30 cases） only underwent KTP laser treatment. The outcome of two groups was compared. Results The surgi- cal success rates of group A and group B were 45.71% and 15.0%, respectively. The difference of success 2 rate was staushcally slgmficant （X = 8.495, P = 0. 005 ）. Conclusion KTP laser combined with intubation has good clinical efficacy for recurrent nasolaerimal duct obstruction.
