目的 探讨下斜肌断腱术与下斜肌前转位术在先天性上斜肌麻痹手术中的应用。方法 对 2 0例单眼先天性上斜肌麻痹 ,且垂直斜视角在 2 0～ 2 5 △ 的病例 ,分两组行下斜肌断腱术和下斜肌前转位术。结果 下斜肌断腱术组治愈率为 4 0 % ,平均欠矫 10 △ 。下斜肌前转位术组治愈率为90 % ,平均欠矫 5 △ 。结论 先天性上斜肌麻痹继发中等程度下斜肌亢进 ,且垂直斜视角在 2 0～ 2 5 △之间的 ,更适合作下斜肌前转位术
Objective To investigate the application of inferior oblique muscle tendon surgery and inferior oblique anterior oblique transposition in congenital superior oblique paralysis surgery. Methods Twenty cases of monocular congenital superior oblique paralysis with a vertical oblique angle of 20 ~ 25 △ were divided into two groups undergoing oblique tendon surgery and anterior oblique transposition. Results Lower oblique tendon surgery group was 40% cure rate, the average undercorrection 10 △. Lower oblique anterior transposition group cure rate was 90%, the average undercorrection 5 △. Conclusions Congenital superior oblique paralysis secondary to secondary oblique hyperthyroidism, and the vertical oblique angle between 20 ~ 25 △, more suitable for inferior oblique anterior transposition
