目的提高儿童中重度先天性上睑下垂的治疗效果。方法对42例(53眼)中重度先天性上睑下垂的儿童施行改良额肌瓣悬吊术:沿重睑线切开皮肤,剪除部分眼轮匝肌,显露睑板,分别作额肌与皮下、额肌与骨膜间的分离,于眉下提起并横形切断额肌,于其内侧向上切开肌瓣达眉上1-1.5cm,外侧向上剪开0.5cm,形成不等边的额肌瓣,三针褥式缝线固定于睑板上缘。结果42例53眼,切口均一期愈合,随访6月～5年,上睑下垂矫正满意,睑缘外形匀称,上睑闭合良好,无复发和并发症。结论改良式额肌瓣悬吊术治疗儿童先天性中重度上睑下垂疗效确切,远期效果较好。
Objective To improve the therapeutic effect of moderate to severe congenital blepharoptosis in children. Methods Forty-two children (53 eyes) with moderate to severe congenital ptosis underwent modified myo-muscle suspension: the skin was cut along the double eyelid line, part of orbicularis oculi muscle was cut off, the tarsal muscles were exposed, Subcutaneous, frontal muscle and periosteal separation, raised under the eyebrow and horizontal cut off the frontal muscle, the medial side of the muscle flap up to reach 1-1.5cm above the eyebrow, the lateral cut upward 0.5cm, the formation of unequal frontal muscle Flap, three-needle mattress suture fixed to the upper edge of the tarsus. Results 42 cases (53 eyes) were cured in one time. The patients were followed up for 6 months to 5 years. The blepharoptosis was satisfactorily corrected. The eyelid appearance was well-proportioned. The upper eyelid closed well without recurrence and complications. Conclusion Modified frontalis muscle suspension for the treatment of congenital moderate to severe pediatric ptosis is effective and long-term effect is better.
