摘　　要：目的　探讨下斜肌部分切除术治疗先天性上斜肌麻痹的效果。方法　观察 17例接受下斜肌部分切除术治疗的先天性上斜肌麻痹术前术后 9方位眼位 ,歪头试验及代偿头位的变化。结果　垂直眼位变化小于 15 △ 的先天性上斜肌麻痹患者术后眼位及代偿头位均恢复 ,大于 15 △ 的仍残留部分眼位异常及代偿头位。结论　下斜肌部分切除术对垂直眼位变化小于 15 △ 的先天性上斜肌麻痹有效。Objective To evaluate inferior oblique muscle myectomy in the management of superior oblique muscle palsy.Methods 17 patients with congenital superior oblique palsy undergone inferior oblique muscle myectomy were evaluated preoperatively and postoperatively(one year).The prism and alternate cover test measurements were made in all nine cardinal positions of gaze.Bielschowsky head tilt test was evaluated quantitatively befor and after the operation.Abnormal head positions were recorded.Results Abnormal head positions and hyperdeviation under 15 prism diopters of the involved eyes were recovedred.Eyes′ hyperdeviation above 15 prism diopters showed apparent residual overaction.Conclusion A myectomy is effective in patients with superior oblique muscle palsy when the direct antagonist is overacting and the hyperdeviation is under 15 prism diopters.
