Congenital anomalies of the orbital roof are rare occurrences. The case of a 2-year-old child with vertical orbital dystopia and abnormalities of the right bony orbit is presented. The patient underwent right orbital reconstruction to restore facial symmetry. A coronal approach with a frontal craniotomy was used for intracranial exposure. The abnormal angulation of the roof was corrected, and the defect was reconstructed with a split-calvarial bone graft harvested from the parietal region. The bone graft was secured with resorbable plate fixation. To preserve vision, reconstruction of this type must be done at an early age, preferably before the age of 4 years. In this patient, there is good facial symmetry and normal globe positioning 5 years after surgery.
眶顶先天性异常较为罕见。本文介绍了一名2岁儿童患有垂直性眶移位及右侧眶骨异常的病例。该患者接受了右侧眼眶重建手术以恢复面部对称性。采用冠状入路联合额部开颅术进行颅内显露。纠正了眶顶的异常角度，并用取自顶叶区域的颅骨劈开骨移植修复缺损。骨移植采用可吸收板固定。为保护视力，此类重建手术必须在早期进行，最好在4岁之前。该患者术后5年面部对称性良好，眼球位置正常。
