Preoperative planning of complex osteotomies in craniomaxillofacial surgery, in conjunction with a surgeon's expertise, is essential for achieving an optimal result. However, the soft tissue changes that accompany facial bone movements cannot yet be accurately predicted. Bony tissue, because of its greater density, can be better predicted, but it alone does not account for the final aesthetic result. A new approach using not only three-dimensional (3-D) surface models of the patient's anatomy, but also a corresponding volumetric model, is discussed. This 3-D planning software was used in the treatment of 15 patients and was found to provide a good correlation between simulation and postoperative outcome.
在颅颌面外科复杂截骨术的术前规划中，结合外科医生的专业知识对于获得最佳效果至关重要。然而，面部骨骼移动所伴随的软组织变化目前仍无法准确预测。骨组织由于密度较大，能够得到更好的预测，但仅骨组织本身并不能决定最终的美学效果。本文讨论了一种不仅使用患者解剖结构的三维（3-D）表面模型，还使用相应体积模型的新方法。这种3-D规划软件应用于15例患者的治疗中，结果发现模拟与术后结果之间具有良好的相关性。
