目的 在睑板上缘附近的上睑提肌内 ,有跨于内外眦角之间数条横向纤维束带即限制韧带 ,我们探讨其在治疗先天性上睑下垂中的意义。方法 将此韧带松解 ,可基本矫正大部分轻度上睑下垂病例。若为轻、中度上睑下垂 ,且韧带松解后上睑仍有部分下垂 ,还需进行上睑提肌腱膜折叠术。重度上睑下垂韧带松解后 ,还需进行眉区额肌筋膜瓣悬吊术。结果 本组 2 7例随访 3个月～ 1年 ,2 7例 40只眼中 38只眼轻、中、重度上睑下垂均矫正满意 ,2只眼良好 ,未见睑下垂复发。结论 松解上睑提肌内限制韧带 ,有助于恢复上睑提肌提睑功能 ,易于矫正睑下垂且手术创伤小 ,形态自然 ,不易复发。
Objective In the levator palpebra superior to the upper edge of the tarsus, there are several transverse fibrous straps that limit the ligaments across the internal and external temples. We explore its significance in the treatment of congenital blepharoptosis. Methods to release this ligament, can be basically correct most cases of mild ptosis. If the light, moderate ptosis, and the release of the upper eyelid is still part of the sagging, the need for levator aponeurosis. Severe ptosis ligament loosening, the amount of eyebrow area myofascial flap should be suspended. Results The group of 27 cases were followed up for 3 months to 1 year, 38 of 27 eyes of 40 eyes were mild, moderate and severe ptosis were corrected satisfactorily, 2 eyes were good, no ptosis recurrence. Conclusion Loosening the ligaments in the levator muscle helps to restore the eyelid function of the levator levator tendon. It is easy to correct the ptosis and has less operation trauma. It is naturally in shape and difficult to relapse.
