ABSTRACT
Image-guided surgery is the logical extension of imaging as it integrates previously acquired radiological or nuclear medicine images with the operative field. In conventional image-guided surgery, a surgeon uses a surgical instrument or a pointer to establish correspondence between features in the preoperative images and the surgical scene. This is not ideal because the surgeon has to look away from the operative field to view the data. Augmented reality guidance systems offer a solution to this problem but are limited by deformation of soft tissues. Real-time intraoperative imaging offers a potential solution but is currently only experimental. The additional precision and confidence that this technology provides make it a useful tool, and recent advances in image-guided surgery offer new opportunities in the field of oral and maxillofacial surgery. Here, we review the development, current technologies, and applications of image-guided surgery and illustrate them with two case reports.
