摘　　要：目的　观察颧骨复合体骨折复位后不同固定方式下颧骨体的稳定性。方法　应用二维图像测量软件Drawdib对 4 4例单侧颧骨复合体骨折患者术后即刻及术后复查华氏位片上颧骨体标志点进行定点 ,比较患侧颧骨体标志点较健侧对应标志点坐标值变化的百分比值以及患侧颧骨下转角较健侧颧骨下转角变化的百分比值。结果　采用 1点至 4点固定各组患者华氏位X线片上反映患侧颧骨体位置的颧骨点 (ju)、颧颌点 (zm)及颧颞下点(ztl)各标志点以及颧骨下转角在颧骨复合体骨折复位固定后没有发生明显的移位变化。结论　 1点至 4点固定各组患者颧骨体复位固定后均较稳定 。Objective To assess the reduction stability of the fractured zygomas with different methods of internal fixation.Methods Forty-four patients with ZMC fractures were involved in this study to measure the changes of the coordinate values of the mark points that representde the position of the zygomas from the images at the immediate postoperation and at least 4 weeks later.Results There have no evidences found to prove that reduction displacement of a fractured ZMC has occurred in patients with either one-point fixation or four-points fixation.Conclusion Stable fixation can be achieved by different methods from only one to four macoplates fixation.
