内直肌边缘切开合并肌联合术治疗麻痹性内斜视

Paralytic esotropia surgery by means of medial rectus marginal myotomy combined with muscle union.

目的 观察肌联合术治疗麻痹性内斜视的作用。方法 2 5例麻痹性内斜视应用内直肌边缘切开术减弱拮抗肌力量 ,应用外直肌与上、下直肌联合术加强麻痹肌。结果 术前第一斜视角 +3 0 3 75°( +66 2 5 △) ,术后 1周残余度数 +6 2 5°( +12 15 △) ,残余以内斜 <10 △ 为良好 ,良好率为 88%。外转范围5 5 7± 0 5 3 5°。结论 外直肌与上、下直肌联合术可使眼球有一定的外展功能。

Objective To observe the effect of muscle union in treatment of paralytic esotropia.Methods The Medial rectus marginal myotomy was performed to reduce antagonist.The muscle union of lateral、superior and inferior rectus was used to strengthen paralytic muscle in twenty-five cases.Results The first strabismus angle of the preoperation was +30.375° (+66.25 △),while at 1 week after operation the angle was +6 25° (+12.15 △).The success rate is 88%.Abduction was 5.57± 0.535°. Conclusion The muscle union of lateral,superior and inferior rectus make eyeball move abductively.
