Abstract

Abstract: Objective: To explore the clinical effect of personalized designed 3D printed composite guide plates in assisting reduction of complex maxillofacial fracture surgery under oral intubation general anesthesia. Methods: Twenty-one patients with complex maxillofacial fractures who were treated at Xuzhou Central Hospital from October 2021 to June 2023 were randomly divided into 3D printed guide plate group (experimental group, 10 cases) and traditional manual reduction group (control group, 11 cases). After surgery, chromatogram evaluation, clinical evaluation, and symmetry evaluation of jaw anatomical landmarks were performed. Results: The experimental group saved an average of about 40 minutes in contrast to the control group, and no related complications occurred after 3 months of follow-up. One patient in the control group still had malocclusion. The chromatogram analysis of the experimental group showed that the mean and maximum deviations from the preoperative virtual surgery model were (0.13±0.97) mm and (2.72±0.99) mm, which were significantly lower than those of control group (0.32±0.23) mm and (3.91±1.02) mm, (P<0.05). The symmetry analysis showed that the experimental group was significantly better than the control group (P<0.05), and the use of guide plate assisted surgery achieved more accurate preoperative expectations (P<0.05). Conclusion: The use of personalized 3D printed composite guide plates can assist surgeons in quickly finding occlusions under oral intubation general anesthesia, shorten surgical time, and achieve precise reduction of fracture segments.
