目的评价提上睑肌-Muller延长术治疗中、重度上睑退缩的效果。方法采用重睑切口,打开眶隔, 暴露提上睑肌前表面。测量睑板上缘处提上睑肌的宽度,将其分成三部分,中央部分占1／2,两侧各占1／4。中央部分的高度以退缩量而定,即保留2mm矫正上睑退缩1mm,沿划线处剪断提上睑肌,将两端的肌肉缝于提上睑肌中央部分上端,术中嘱患者坐位以观察上睑的位置和轮廓,必要时需调整,皮肤以重睑成形方式缝合。结果 16例 (20只眼)行提上睑肌-Muller肌延长术,随访6-24个月,平均10．2个月。其17只眼在原位注视时上睑位于角膜缘下1-2mmm,2只眼过矫,1只眼欠矫。大部分病例在术后1个月内上睑位置多较低,而于术后3个月时上睑基本恢复至满意位置。全部病例手术效果满意。结论提上睑肌-Muller肌延长术可获得了良好的功能和美容双重效果,应为目前治疗中、重度上睑退缩的良好方法。
Objective To evaluate the effect of levator muscle lengthening on the treatment of moderate and severe upper eyelid degeneration. Methods Double eyelid incision was used to open the orbital septum to expose the levator anterior surface. Measure the width of the levator muscle at the upper edge of the tarsus, divide it into three parts, one half of the central part, and one on each side. The central part of the height of the retreat, which retained 2mm correction of the upper lid retraction 1mm, along the scribe at the levator muscle cut, the two ends of the muscle stitched to the upper part of the central levator muscle, Zhu Huanzhe patients were sitting to observe The position and contour of the upper eyelid, need to be adjusted if necessary, the skin sutured with double eyelid formation. Results 16 cases (20 eyes) underwent levator muscular lengthening operation, followed up for 6-24 months with an average of 10.2 months. The 17 eyes in situ when the upper eyelid is located in the corneal limbus 1-2mmm, 2 eyes overcorrection, 1 eye less correction. In most cases, the position of upper eyelid was lower in 1 month after operation, and the upper eyelid recovered to satisfactory position at 3 months after operation. Satisfactory results in all cases. Conclusions The levator muscular lengthening technique has obtained good dual function of function and beauty and should be a good method for the treatment of moderate and severe upper eyelid retraction.
