LeFortⅠosteotomy is an important surgical method in midfacial obsolete fractures management. The cephalometric radiography and model surgery should be performed depending on the principles of orthognathic surgery before LeFort Ⅰosteotomy. The other fractures of facial bones besides maxilla should be managed surgically in the same operation.

LeFort Ⅰ型截骨术是治疗陈旧性面中部骨折的重要手术方法，术前应依照正颌外科原则进行X线头影测量和模型外科准备，术中应同期进行上颌骨骨折之外的其他面骨骨折的复位固定。

The result supports this approach to be a reliable method in cephalometric analysis and worthy to research in the future.

结果显示上述方式为一可靠的测颅方法，值得未来再进一步深入研究。

Kerbs and the others used the metallic implants to investigate the effects of RME to perfect the cephalometric method.

这种方法在一定程度上弥补了x线片的影像重叠的不足，但不能成为常规的研究手段。

Experimental results demonstrate desirable performance. We also propose a multi-component ASM based cephalometric landmarking method.

3对已有头影图像测量分析中标志点定位方法归纳总结的基础上，分别对基于边缘跟踪和基于ASM的标志点定位算法进行了研究。

Methods:Based on the principle of finite element method and getting three-dimensional coordinates from lateral and frontal cephalometric X-ray films by Baunrind,the landmarks on cephalometric X-ray films were selected as nodes,by which the hard tissue was divided into four noded and pyramidal elements according to anatomic structures and their relationship.

基于有限元分析和Baunrind用头颅正、侧位定位片获取标志点三维坐标的原理，以硬组织标志点作为节点，按照解剖结构及结构间关系对硬组织进行单元划分。

Cephalometric floating norms provide a useful method for X-ray analysis for adult patients, especially for patients who may undergo orthognathic surgery as part of their overall treatment regimen.

本研究为成人正畸患者提供了一套个体化的头影测量诊断方法，为拟进行正颌外科治疗的成人患者制定正确的手术方案提供了重要依据。

Meanwhile we measured the skeletal classⅢocclusion and mandibular retrusion patients by traditional cephalometric analysis and the Delaire cephalometric analysis. We discovered the Delaire cephalometric analysis was more accurately and conveniently. This method can help us to understand the cranio-maxillo-facial structure compensatory mechanism of the skeletal classⅢocclusion and mandibular retrusion patients, which can provide reference for diagnosis, project and orthodontic treatment.

同时，传统头影测量方法与Delaire头影测量分析法对骨性Ⅲ类与青少年下颌后缩畸形行测量，发现Delaire头影测量分析法更直观、定量，利于明确骨性Ⅲ类错牙合与青少年下颌后缩畸形颅面骨骼结构补偿机制，更易辅助正畸诊断、设计，也为相应的临床治疗方法改良提供依据。

The conventional cephalometric analysis chosen SNA, SNB, ANB, NA-PA etc to reflect the protrusion or retrusion of maxillary and Mandible, but they can't reflect this extent quantitatively. The Delaire cephalometric analysis can analyze the protrusion or retrusion of maxillary and Mandible quantitatively through Me-F1,Me-Met,Np-F1 etc. This method combine with conventional methods can evaluate accurately, quantitatively and directly.

传统头影测量分析选用SNA、SNB、ANB、NA-PA等角度来反映上下颌的前突或后缩，并不能定量的反映上下颌前突或后缩的程度；而Delaire头影测量分析中Me-F1，Me-Met，Np-F1可定量分析上下颌前突或后缩程度，结合传统的角度测量将利于直观、定量的评价，也利于准确的诊断设计。
