上下直肌止端部分移位术治疗外伤性外展神经麻痹性斜视

Surgical management of abducens nerve paralytic strabismus

目的探讨外伤性外展神经麻痹性斜视的手术效果及术后并发症。方法对11例外伤性外展神经麻痹患者,应用上下直肌止端部分移位术配合对抗肌后徙术进行矫治和观察。结果术后2例眼位为正位,眼球外转有改善者9例。10只眼有不同程度的眼球后退占87%;7例术后仍有复视占64%。结论上下直肌止端部分移位术配合对抗肌后徙是外伤性外展神经麻痹性斜视的一种部分有效的治疗方法。

Objective To investigate the surgical effects and complications of traumatic abducens paralytic strabismus. Methods 11 cases of abducens paralytic strabismus caused by orbit injury were treated by partial superior and inferior rectus muscle transposition and antagonist weakening. Results After treatment, 2 cases were straightened out to primary position, and the abduction function of 9 cases were notably improved. 10 eyes differently retracted （87%） ; 7 cases still had diplopia （64%）. Conclusions Partial superior and inferior rectus muscle transposition and antagonist weakening is a kind of partial effective treatment for traumatic abducens paralytic strabismus.
