方法：根据手术方式分为四组：行双眼额肌筋膜瓣悬吊术组(A组，21例42眼)，行双眼提上睑肌缩短术组(B组，19例38眼)，行单眼额肌筋膜瓣悬吊术组(C组，24例24眼)，行单眼提上睑肌缩短术组(D组，29例29眼)。随访观察各组患者术后的功能和外观疗效。

结果：(1)术后早期两种手术方式功能成功率均达100%，术后晚期提上睑肌缩短术的功能成功率(97.01%)高于额肌筋膜瓣悬吊术(87.88%)，两者差异具有统计学意义(P<0.05)。(2)术后早期两种手术方式的外观疗效差异无统计学意义(P >0.05)； 术后晚期，B组“眼睑弧度”、“双重睑”两项外观疗效指标优于A组(P<0.01)； D组“眼睑弧度”、“眼睑高度对称”、“双重睑”三项外观疗效指标优于C组(P<0.01)。

结论：两种手术方式治疗先天性上睑下垂均具有较好的疗效； 在外观疗效上提上睑肌缩短术更有优势。

METHODS: The patients were divided into four groups according to the operation method: Patients undertook bilateral fascial suspension surgery as Group A(42 eyes of 21 cases); Patients undertook bilateral levator muscle shortening surgery as Group B(38 eyes of 19 cases); Patients undertook unilateral fascial suspension surgery as Group C(24 eyes of 24 cases); Patients undertook unilateral levator muscle shortening surgery as Group D(29 eyes of 29 cases). Each group patients were followed for postoperative function and appearance effect.

RESULTS: 1)Early postoperative of two operation function success rate was up to 100%, the function of levator muscle shortening surgery was 97.01% in the late postoperative, was higher than bilateral fascial suspension surgery(87.88%), with statistical difference in both surgerys(P<0.05). 2)Appearance effect of two kinds of operation method in early postoperative had no statistical difference(P >0.05); In the late postoperative, the mean grades for “Lid Contour” and “Lid Crease” of Group B were better than that of Group A(P<0.01). While the mean grades for “Lid Contour”, “Symmetry of Lid Height” and “Lid Crease” of Group D were similarly better than that of Group C(P<0.01).

CONCLUSION: Two kinds of operation method have good effects on the treatment of congenital ptosis. In terms of cosmetic effect, levator muscle shortening surgery is better.
