Monobloc Le Fort III distraction osteogenesis allows superior skeletal advancement in treating severe syndromic craniosynostosis. We report a rare orbital complication in a 3-year-old boy with Crouzon syndrome who developed right-eye exodeviation with limited abduction during the intradistraction period following this surgery. Images from a computed tomography scan confirmed direct impingement of the distracted right lateral orbital wall to the lateral rectus muscle. The impingement was surgically relieved via lateral orbital wall osteotomy. Ten months postdistraction, a review showed normal eye movement. A lateral orbital osteotomy cut for a monobloc Le Fort III distraction should be designed near the rim to prevent this complication.
整块式勒福Ⅲ型牵引成骨术在治疗严重综合征性颅缝早闭症时能实现上颌骨的显著前移。我们报告了1例3岁克氏综合征男孩的罕见眼眶并发症，该患儿在接受此手术后的牵引期内出现右眼外斜视且外展受限。计算机断层扫描图像证实，右侧牵引的眶外侧壁直接压迫外直肌。通过眶外侧壁截骨术手术解除了压迫。牵引10个月后的复查显示眼球运动正常。整块式勒福Ⅲ型牵引的眶外侧截骨切口应设计在眶缘附近，以预防这种并发症。
