PURPOSE
To introduce myectomy of the lateral rectus muscle for correcting exotropia in patients with third nerve palsy.
METHODS
The lateral rectus muscle of the paretic eye was myectomized without suturing it to the globe. This was combined with a medial rectus muscle resection and a contralateral lateral rectus muscle recession. Magnetic resonance imaging was performed to observe the re-attachment of the lateral rectus muscle to the globe.
RESULTS
The patient was able to fuse in the primary position without any noticeable limitation in abduction. Magnetic resonance imaging showed that the lateral rectus muscle was attached to the globe through fibrous tissue.
CONCLUSION
Myectomy of the lateral rectus muscle is an effective and simple procedure to accomplish a super-maximal weakening effect of abduction in patients with complete third nerve palsy.
目的
介绍通过外直肌切除术治疗动眼神经麻痹患者的外斜视。
方法
对麻痹眼的外直肌进行切除术，不将其缝合至眼球。此手术联合内直肌切除术和对侧外直肌后徙术。进行磁共振成像以观察外直肌与眼球的重新附着情况。
结果
患者在第一眼位能够融合，外展无明显受限。磁共振成像显示外直肌通过纤维组织附着于眼球。
结论
外直肌切除术是一种有效且简单的手术方法，可对完全性动眼神经麻痹患者实现外展的超最大程度减弱效果。
