单纯皮肤缩短术治疗老年性上睑下垂

Clinical study on simplex skin excision treating blepharoptosis

目的:观察单纯皮肤缩短术治疗老年性上睑下垂的效果。方法:对21例75岁以上老年性上睑下垂患者39只眼手术前、后测量肌力、上睑缘角膜映光距离(MRD)、眼睑下垂量;术后观察双侧眼睑形态、睑裂高度。结果:术前测量MRD值为(0.5±1.8)mm,术后测量值为(2.8±0.9)mm,两者差异具有统计学意义(P<0.05)。术后双眼睑裂明显增大,视野宽阔,双侧睑裂高度基本对称,双眼闭合感觉良好。随访观察无并发症发生。结论:单纯皮肤缩短术是治疗老年性上睑下垂尤其是75岁以上患者较理想而简单的手术方法。

Objective： To observe the effect of treating blepharoptosis by simplex skin excision. Methods： The strength of levator palpebrae superioris muscle, the value of margin reflex distance （MRD） of upper eyelid and the degree of ptosis were measured pre-operation and post-operation in 21 patients aged more than 75 with blepharoptosis. The general appearance of both upper eyelids and the width of palpebral fissure was observed. Results： MRD value was （0.5 ± 1.8 ） mm pre-operation and （ 2.8 ± 0.9 ）mm post-operation, and the difference was significant （ P 〈 0.05 ）. The width of palpebral fissure was increased markedly and symmetrical in both eyes. The visual field of patients was improved and the eyes could be closed naturally. Conclusion： The simplex skin excision can be considered one of ideal methods treating blepharoptosis, especially in patients aged more than 75.
