目的观察显微镜下采用显微技术行直肌联结术治疗外直肌麻痹的手术效果。方法回顾分析从2005年1月～2007年7月显微镜下行直肌联结术联合同侧内直肌后退矫正13例15眼完全性或近完全性外直肌麻痹的手术效果。随访时间1个月至2年。结果一次手术后正位7例8眼,4例5眼欠矫<10°,2例2眼欠矫15°。术后平均外转过中线达11°(5°￣20°)大部分病例外观满意,外转功能有不同程度改善,未发现眼前节缺血等并发症。结论直肌联结联合同侧内直肌后徙术治疗外直肌麻痹效果理想,显微镜下分离睫状血管降低了眼前节缺血发生的风险。
Objective To observe the surgical effect of microsurgery for the treatment of external rectus paralysis by microsurgical technique. Methods From January 2005 to July 2007, retrograde microsurgical rectus abdominis rectus combined with rectus medialis rectus retrospectively corrected 13 cases (15 eyes) of complete or near complete rectus abdominis paralysis. Follow-up time of 1 month to 2 years. Results After operation, 7 eyes were in 8 cases, 4 eyes were under-corrected in 5 eyes <10 °, and 2 eyes were under-corrected in 15 eyes. Average external rotation of the midline reached 11 ° (5 ° ~ 20 °) in most cases the appearance of satisfactory external rotation function improved in varying degrees, no anterior segment ischemia and other complications were not found. Conclusion Rectus muscle combined with ipsilateral rectus muscle rectus surgery for external rectus paralysis ideal results, microscopically separated ciliary vessels reduce the risk of anterior segment ischemia.
