P-36666249-244 - Oral maxillofacial trauma treatment using computer assisted surgery.

Abstract

In recent years, clinical application of three-dimensional treatment planning using computer simulation constructed from image data and patient biometric information has been progressing. Computer-assisted surgery (CAS) using simulation-based navigation systems and surgical guides has been introduced for oral and maxillofacial surgery. The 3D model created based on the preoperative image data can determine the preoperative surgical plan and the reduction site of the bone and is very useful for the treatment of maxillofacial fractures. In addition, the intraoperative navigation system captures the three-dimensional anatomical position by linking the surgical site on the CT or MRI image and displaying the positional relationship between the position seen by the operator and the target on the monitor in real time. It is a computer surgery support system that is widely used in many oral and maxillofacial surgeries. However, the problem with conventional navigation systems is that the intraoperative display image cannot be updated. This is because the navigation system is based on preoperative image data. In recent years, it has become possible to use CT images taken during surgery by using a hybrid operating room, and even in maxillofacial fracture surgery involving bone movement, intraoperative evaluation is possible by using a navigation system with images taken after movement. Yes, its usefulness is increasing. In this presentation, we would like to examine the usefulness and future prospects of computer-assisted surgery in oral and maxillofacial trauma surgery together with cases.
