睑袋成形术后眼轮匝肌功能状态的临床研究

目的探讨睑袋成形术后眼轮匝肌的功能状态及其影响因素。方法用肌皮瓣法矫正下睑袋32例（64眼），分别在术前和术后5d、14d、1个月、3个月和6个月，以结膜囊染料消失法进行泪囊排泄功能测试。结果术后5d、14d和1个月结膜囊染料消失时间较术前明显延长（P〈0．001），3个月和6个月检测结果与术前相比差异无统计学意义（P〉0．05）。结论肌皮瓣法睑袋成形术，术后早期眼轮匝肌泵作用明显减弱；但术中精细操作，减少对组织的损伤，有利于术后眼轮匝肌泵功能的恢复。

Clinical study in the functional state of the orbicularis oculi muscle after lower lid blepharoplasty

Objective To study the functional state and the influencing factors of the orbicularis oculi muscle after lower lid blepharoplasty. Method 32 patients （64 eyes） with eyelid bagswere performed lower lid blepharoplasty with a myocutaneous flap method. Before and 5, 14, 30, 90 and 180 days, the lacrimal sac excretion function was detected with the method of the （lye disappearing in eonjunctival sac. Results The time of the dye disappearing in eonjunetival sac was markedly prolonged at the 5 d, 14 d, 30 d after operation （ P 〈 0. 001 ） , but it had no significant difference between the before operation day and 90 d, 180 d after the operation （ P 〉 0.05 ）. Conclusion The function of the orbieularis oeuli muscle is obviously weakness in the earlier post-period of lower lid blepharoplasty with a myocutaneous flap method. It is necessary to operate carefully and alleviate the injury of tissue in opetating, which will be helpful for the functional reenvery of orbicularis oculi muscle.
