A case of transient abducens nerve palsy following Le Fort I maxillary osteotomy is reported. The results of the CT scan strongly suggest the cause was a fracture of the body of the sphenoid bone but the cause of the fracture is unclear. The palsy occurred on the first postoperative day and recovery took approximately 5 months. The most likely explanation for the complication is a transmittal of force from the osteotome used to fracture through the pterygoid plates extending superiorly through the medial surface of the cavernous sinus. This case clearly demonstrates the importance of care in positioning of the pterygomaxillary osteotome.
报告了1例勒福Ⅰ型上颌骨截骨术后出现短暂性展神经麻痹的病例。CT扫描结果强烈提示病因是蝶骨体骨折，但骨折原因尚不清楚。麻痹于术后第1天出现，恢复过程约持续5个月。该并发症最可能的解释是，用于截骨的骨凿所传递的力量通过翼突板向上延伸至海绵窦内侧表面。本病例清楚地证明了翼上颌骨凿定位时小心操作的重要性。
