目的：分析并比较改良式眼轮匝肌缩短术及单纯眼轮匝肌缩短术治疗退行性下睑内翻伴眼睑松弛的临床疗效。

方法：选取2012-01/2014-08我科收治的93例108眼退行性下睑内翻伴眼睑松弛为研究对象，根据手术方式的不同分为观察组(47例52 眼，采用改良式眼轮匝肌缩短术)和对照组(46例56眼，采用单纯眼轮匝肌缩短术)。比较两组患者的短期和长期治疗效果。

结果：观察组与对照组患者在年龄、性别及病程方面比较，差异无统计学意义(P>0.05)。观察组的短期有效率(98%)与对照组(95%)比较，差异无统计学意义(P>0.05)； 观察组术后3a的复发率(2%)低于对照组(14%)，差异有统计学意义(P=0.033)。

结论：改良眼轮匝肌缩短术治疗退行性下睑内翻伴眼睑松弛较单纯眼轮匝肌缩短术的临床疗效好。

METHODS: From January 2012 to August 2014, ninety-three cases(108 eyes)diagnosed as involutional entropion of lower eyelid with blepharochalasis were enrolled in our study. According to different surgical methods, patients were divided into observation group(52 eyes in 47 cases)and control group(56 eyes in 46 cases). The observation group was performed on the modified orbicularis muscle shortening procedure, and the control group was using a simple orbicularis muscle shortening method. The general datum, short-term clinical effect and long-term clinical effect were collected to compared between two groups.

RESULTS:The age, gender and the course of disease were no significance differences between the observation group and the control group(P>0.05). There was no statistical significance on the short-term effective rate(P>0.05)between the observation group and the control group(98% vs 95%, respectively). The long-term recurrence rate of the observation group was 2%, while the control group was 14%. It had a significance statistical difference between two groups(P=0.033).

CONCLUSION: The clinical curative effect of modified orbicularis oculi muscle shortening procedure, in the treatment of lower eyelid entropion with blepharochalasis, is better than the orbicularis muscle shortening procedure's.
