Anterior Transposition of Inferior Oblique in the Treatment of Congenital Superior Oblique Palsy

目的观察下斜肌前转位术治疗先天性上斜肌麻痹的疗效。方法8例(8眼)先天性上斜肌麻痹患者,均存在代偿头位,三棱镜检查垂直斜视度平均为28.58△。患者均于全麻下行下斜肌前转位术,术后随访观察其代偿头位和垂直斜视度的变化。结果术后3月代偿头位改善和消失各4例;术后1周、6月和3年随访检查显示,垂直斜视度均较术前减小,平均为6.25△无1例出现手术过矫和并发症。结论采用下斜肌前转位术治疗先天性上斜肌麻痹安全有效。

Objective To observe the effect of anterior transposition of the inferior oblique in the treatment of congenital superior oblique palsy. Methods Anterior transposition of inferior oblique was performed on 8 patients （8 eyes） with congenital superior oblique palsy. Before operation, all 8 patients had compensated head rotation; the mean prismatic degree was 28.58^△ . The patients＇ head position and vertical deviation were observed after operation. Results Three months after operation head position disappeared in 4 patients, and the others 4 partly disappeared. Vertical deviation decreased in all patients, and the mean prismatic degree was 6.25^△. There was no over correction. Conclusion Anterior transposition of inferior oblique is safe and effective in treating congenital superior oblique palsy.
