AIM: To analyze and compare the clinical effect in treatment of degenerative entropion of lower eyelid with blepharochalasis between the modified orbicularis oculi muscle shortening procedure and orbicularis muscle shortening procedure.

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.
