目的:分析改良结膜上穹窿联合筋膜鞘悬吊及部分提上睑肌复合体缩短术治疗先天性重度上睑下垂效果.方法:取2020年2月到2021年2月中入院的108例(206只眼)先天性重度上睑下垂患者进行研究,对照组54例(96只眼)采用改良结膜上穹窿联合筋膜鞘悬吊术治疗,研究组54例(106只眼)采用改良结膜上穹窿联合筋膜鞘悬吊及部分提上睑肌复合体缩短术治疗,比较两组疗效、并发症发生率、满意度.结果:研究组矫治效果和满意度比对照组高,研究组并发症发生率比对照组低,P＜0.05存在差异,有统计学意义.结论:采用改良结膜上穹“,”Objective: to analyze the effect of modified superior conjunctival fornix combined with fascial sheath suspension and partial shortening of levator palpebrae muscle complex in the treatment of congenital severe blepharoptosis. Methods: 108 patients (206 eyes) with congenital severe blepharoptosis admitted from February 2020 to mid February 2021 were studied. 54 patients (96 eyes) in the control group were treated with improved superior conjunctival fornix combined with fascial sheath suspension, and 54 patients (106 eyes) in the study group were treated with improved superior conjunctival fornix combined with fascial sheath suspension and partial shortening of levator palpebrae muscle complex. The curative effects of the two groups were compared Complication rate and satisfaction. Results: the correction effect and satisfaction of the study group were higher than those of the control group, and the incidence of complications in the study group was lower than that of the control group (P ＜ 0.05). Conclusion: the improved superior conjunctival fornix combined with fascial sheath suspension and partial shortening of levator palpebrae muscle complex in the treatment of congenital severe blepharoptosis has significant effect, less complications and higher patient satisfaction, which is worthy of popularization.
