目的评估经典提上睑肌缩短术治疗重度先天性上睑下垂及手术治疗效果。方法重度先天性上睑下垂20眼行经典提上睑肌缩短术结果本文16例20眼,平均随访6个月。术后睑裂高度7～9mm者18眼,6mm者2眼,双眼睑裂对称,重睑弧度自然,部分病例有轻度睑裂闭合不全,4眼一过性轻度结膜脱垂。结论该术式矫正重度先天性上睑下垂效果良好。 Objective To evaluate the classic levator muscle shortening for the treatment of severe congenital ptosis and surgical treatment. Methods 20 cases with severe congenital ptosis underwent classic levator muscle shortening. Results In this paper, 16 cases of 20 eyes were followed up for an average of 6 months. Postoperative palpebral fissure height of 7 ~ 9mm in 18 eyes, 6mm in 2 eyes, bilateral palpebral fissure symmetry, double eyelid curvature of the natural, in some cases mild palpebral fissure insufficiency, 4 eyes had transient mild conjunctival prolapse.
