项目摘要

Clinically, it became, possible to acquire three-dimensional (3-D) and more detailed information by using image processing of the CT image data. However, the precious pre-operative planning before the oral and maxillofacial operation has been barred by anatomical complexity and the size of variation as compared with another region. Recently the simulation surgery which can also be called virtual reality using the 3-D actual model became possible. However, there are the following problems in the 3-D actual model. That is, it is very expensive, requires time for production, and harder than the actual bone, etc. Then, in this research, CT data of the maxilla and mandible before the operation was reconstructed in three dimensions using image processing software on the personal computer. It investigated whether it would be useful as a preoperative simulation with the actual prediction comparing with intra-operative findings or post-operative examinations. In the cases of orthognathic surgery or osteomyelitis of the mandible, prediction of the operation was exact and the proper result was obtained. From these results, it was thought that this pre-operative simulation had clinically sufficient meaning. In the future, development of more useful software will progress with development of hardware. Consequently, the more easy simulation of the operation will become possible and the more exactly postoperative prediction will be attained. If it becomes so, for the patient who undergoes the operation of oral and maxillofacial region, it will become good news.

在临床上，通过对CT图像数据进行图像处理，可以获得三维（3-D）和更详细的信息。然而，由于解剖复杂性和与其他区域相比变异的大小，在口腔颌面手术前进行宝贵的术前计划受到了限制。近年来，利用三维实际模型的模拟手术也被称为虚拟现实成为可能。然而，在三维实际模型中存在以下问题：也就是说，它非常昂贵，需要时间来制作，并且比实际的骨头更硬等等。然后，在本研究中，在个人电脑上使用图像处理软件对上颌和下颌骨术前的CT数据进行三维重建。它研究了与术中发现或术后检查相比，它作为术前模拟和实际预测是否有用。在正颌手术或下颌骨骨髓炎的情况下，手术预测准确，获得适当的结果。从这些结果来看，认为这种术前模拟具有足够的临床意义。在未来，更多有用的软件的开发将随着硬件的发展而进步。因此，更容易的模拟手术将成为可能，并获得更准确的术后预测。如果能做到这一点，对于接受口腔颌面手术的患者来说，将是一个好消息。
