方法：对2006-01-01 /2012-12-31收治的老年性下睑内翻患者，按手术方法不同分为两组：A组采用眼轮匝肌缩短改良术，20例38眼； B组采用眼睑皮肤轮匝肌切除术，21 例36眼。术后坚持随访，观察术后效果。

结果：术后随访 1～2a，A组20例38眼均治愈，未见复发； B组治愈16例29眼，治愈率81%，未愈5例7眼，未愈率19%，复发7 眼，复发率 19%，两组手术后治愈率、未愈率、复发率的差异均具有统计学意义(P<0.05)。

结论：对于老年性下睑内翻患者行眼轮匝肌缩短改良矫治手术，治疗效果良好稳定。

METHODS: From January 01, 2006 to December 31, 2012, senile patients with lower eyelid were divided into two groups according to different surgical methods. Group A with the orbicularis muscle shortening improved operation in 20 cases(38 eyes), group B used the eyelid skin orbicularis muscle resection in 21 cases(36 eyes). The effects of surgery were followed-up postoperatively.

RESULTS: Patients were followed up for 1-2a, 20 patients(38 eyes)in group A were cured without recurrence; 7 eyes recurred in group B, the recurrence rate was 19%, the recurrence rate after surgery both groups were statistically significant(P<0.05).

CONCLUSION: The effect of orbicularis muscle shortening improved operation for senile entropion is good and stable.
