摘要
目的 通过对颧骨复合体骨折 (ZCF)的临床及影像学研究 ,探索对临床治疗有指导意义的新分类方法及相应的治疗原则。方法 2 0 6例 (2 12侧 )ZCF患者术前术后拍摄华氏位、改良颅底位片 ,复杂病例行CT扫描和三维骨重建。利用计算机辅助平面测量系统对骨折移位程度测量 ,结合临床面部畸形情况分类 ,并提出相应的治疗原则。结果 根据面部畸形和颧骨移位程度及方向将ZCF分为 3型 6个亚型 ,确定各型的治疗原则 ,经过临床实践及术后影像学评价 ,效果满意。结论 ZCF的治疗应根据其类型选择相应的切口和复位方法 ,手术复位的关键是恢复颧骨外形高点 ,重塑颧弓长度及弧度是实现颧突点复位的最基本保证 ,颧蝶缝和颧上颌连接的对位是两个重要的参考指标。
Objective To investigate a new classification and treatment of zygomatic complex fractures (ZCF) by clinical and radiographic studies. Methods Standard radiographs with Waters,submental vertex views had been obtained before and after operation in 206 patients (212 sides) with ZCF. Patients with complicated fractures underwent two and three dimensional CT. Computer-assisted measuring system was used to measure the degree of displacement. Results ZCF were classified into 3 types and 6 subtypes according to the degree of displacement of segments and facial deformities. Treatment principles were proposed. The results were satisfied through clinical application and measurement of post-operative images. Conclusions The treatment for ZCF should be selected according to the fracture types. The key of operation is to recover the malar prominence. Remodeling the length and radian of zygomatic arch guarantee the recovery of malar prominence. Zygomatic-sphenoid and zygomatic-maxillary fissures are very important reference marks for reduction and fixation.
