Objective To explore the feasibility and efficacy of levator muscle resection in se-vere blepharoptosis,and to provide a basis for rational clinical treatment.Methods Twenty-six patients with severe blepharoptosis(32 eyes)were assigned to receive either levator muscle resec-tion(levator muscle resection group,n=1 6 )or frontalis muscle flap suspension(frontalis muscle flap suspension group,n=10)between February 2011 and March 2012.Patients were followed up for 1 year and curative effects were compared between the two groups.Results In levator muscle resection group,undercorrection was found in 2 eyes and overcorrection in 1 eye.In frontalis mus-cle flap suspension group,undercorrection was found in 1 eye and overcorrection in 1 eye.All of the other eyes were restored with beautiful appearance after 1 year of follow-up.No palpebral var-us,conj unctival fornix prolapse and other complications were found in both groups.The cure rate was 85.0% in levator muscle resection group and 83.3% in rontalis muscle flap suspension group.There was no significant different in the cure rate between the two groups(P>0.05).Con-clusion Levator muscle resection can effectively improve eyelid function and appearance in the treatment of severe blepharoptosis.%目的：探讨提上睑肌缩短法治疗重度上睑下垂的可行性及疗效，为临床合理治疗提供依据。方法将2011年2月至2012年3月来南昌大学第一附属医院接受手术的26例（32只眼）严重上睑下垂患者，按照不同手术方式分为：提上睑肌缩短术组16例，额肌瓣悬吊术组10例。随访1年，比较提上睑肌缩短术与公认的额肌瓣悬吊术治疗重度上睑下垂的疗效。结果提上睑肌缩短术组术后2只眼欠矫，1只眼过矫，额肌瓣悬吊术组术后1只眼欠矫，1只眼过矫。其余随访1年上睑下垂均得到恢复，无睑内外翻、穹窿结膜脱垂等并发症，且外形美观。2组治愈率分别为85．0％、83．3％，差异无统计学意义（P＞0．05）。结论提上睑肌缩短法治疗严重上睑下垂，在矫正眼睑生理功能和改善外观上均达到满意的效果。
