Abstract
The oral craniomaxillofacial region is adjacent to the cranium with complex anatomical structures. Therefore, precise and minimally invasive surgeries are essential for preserving its function and reconstructing its appearance. The most commonly used method is optical surgical navigation technology. Compared with preoperative computed tomography image registration, the accuracy of intraoperative navigation can be calculated to help surgeons judge the effect of surgery. This study aimed to introduce laser scanning in craniomaxillofacial bone surgery, so as to create a new method of navigation accuracy verification, and compare the image with the preoperative plan. The experimental results of this study showed that the average accuracy of point verification calculation was greater than 3[Formula: see text]mm, which was much greater than the average accuracy of laser scanning plane verification based on mixed Student [Formula: see text] distribution (less than 1[Formula: see text]mm), and a statistically significant difference was found between them. It was demonstrated that relying solely on individual points to depict the operation of the entire bone surface was insufficient in navigation surgery.
