The goal of craniofacial reconstruction is not only life-saving but also facial aesthetics. From this viewpoint the authors evaluated the facial symmetry of patients after craniofacial reconstruction. The subjects were seven patients reconstructed after craniofacial resections. Their CT or MR images were evaluated just after surgery, 1 month after surgery, and 6 months after surgery. Based on these images, the proportion of simple area (PSA) and the proportion of overlapped area (POA) were calculated. The PSA is the proportion of the reconstructed quarter to the contralateral one, and the POA is the proportion of the overlapped area in the reconstructed quarter to the normal one. These values were assessed in two groups: five patients without and two with split calvarial bone grafts. Results demonstrated that the volumetric change of the reconstructed face with the bone graft was relatively stable.
颅面重建的目标不仅是挽救生命，还包括面部美观。从这一观点出发，作者评估了颅面重建术后患者的面部对称性。研究对象为7例颅面切除术后接受重建的患者。分别在术后即刻、术后1个月和术后6个月对他们的CT或MR图像进行评估。基于这些图像，计算简单面积比例（PSA）和重叠面积比例（POA）。PSA是重建侧四分之一区域与对侧相应区域的比例，POA是重建侧四分之一区域中重叠部分与正常侧的比例。这些值在两组中进行评估：5例未使用劈开颅骨骨移植的患者和2例使用劈开颅骨骨移植的患者。结果表明，使用骨移植的重建面部的体积变化相对稳定。
