摘要目的 观察应用横切纵缝的改良上睑提肌延长法治疗医源性上睑退缩的临床效果.方法 设计延长瓣时,将传统上睑提肌瓣梯形切口改为水平切口,按上睑退缩量1∶2在提肌腱膜中央设计横行切口,沿设计线切开提肌腱膜米勒肌复合体,纵行缝合切口.结果 共治疗5例6侧医源性上睑退缩,术后随访3～12个月,除1例单侧上睑退缩术后左右重睑宽度稍有不对称外,其余4例效果满意,双侧角膜暴露度对称,无复发和并发症.结论 改良上睑提肌延长法矫正医源性上睑退缩,具有操作简单、高度容易调整及并发症少等优点,对轻度、中度的医源性上睑退缩的治疗疗效确切.

abstractsObjective To evaluate the effect of correcting upper eyelid retraction in patients with iatrogenic ophthalmopathy by a new technique of modified transsection and longitudinal suture levator muscle prolongation treatment.Methods The traditional levator muscle flap trapezoidal incision was changed into horizontal incision,According to the amount of upper eyelid retraction we designed a transverse incision with 1 ∶ 2 in the central part of levator aponeurosis.Along the line of incision was designed transverse incision of Mulller's muscle combined with levator aponeurosis complex was designed,with longitudinal suture of incision.Results Five patients (6 eyes) with iatrogenic upper eyelid retraction were treated by this method.The follow up was performed for 3 to 12 months.All were satisfied with good cosmetic results,the degree of bilateral corneal exposure was symmetrical,with no recurrence and complications,except for 1 cases of unilateral upper eyelid retraction width slightly asymmetry.Conclusions The application of modified levator muscle prolongation treatment is not only quite simple,easy to adjust in operation,but also with reliable effect and less complication.It is effective for iatrogenic upper eyelid retraction range from mild to moderate degrees of correction.
