Background: This systematic review summarizes recent literature on the use of extended reality, including augmented reality (AR), mixed reality (MR), and virtual reality (VR), in preoperative planning for orbital fractures. Methods: A systematic search was conducted in PubMed, Embase, Web of Science and Cochrane on 6 April 2023. The included studies compared extended reality with conventional planning techniques, focusing on computer-aided surgical simulation based on Computed Tomography data, patient-specific implants (PSIs), fracture reconstruction of the orbital complex, and the use of extended reality. Outcomes analyzed were technical accuracy, planning time, operative time, complications, total cost, and educational benefits. Results: A total of 6381 articles were identified. Four articles discussed the educational use of VR, while one clinical prospective study examined AR for assisting orbital fracture management. Conclusion: AR was demonstrated to ameliorate the accuracy and precision of the incision and enable the better identification of deep anatomical tissues in real time. Consequently, intraoperative imaging enhancement helps to guide the orientation of the orbital reconstruction plate and better visualize the precise positioning and fixation of the PSI of the fractured orbital walls. However, the technical accuracy of 2–3 mm should be considered. VR-based educational tools provided better visualization and understanding of craniofacial trauma compared to conventional 2- or 3-dimensional images.

“…We carefully examined the qualifying papers and closely examined the paper titles and abstracts, all while adhering to the PRISMA requirements. 14 The PRISMA flow diagram used to determine research is displayed in Figure 1. To guarantee accuracy and dependability, we meticulously chose and planned the right clinical trials.…”

“…. (14,15) Because of the intricacy of the surgical procedures, it still presents a technical challenge for orbital surgeons even with the recent advancements in the creation of new implant materials and surgical technique.

This systematic review investigates the current methods and long-term results of maxillofacial surgery orbital defect restoration with personalized implants. PRISMA standards were followed in order to identify and analyze pertinent studies that focused on patient-specific implants (PSI) for orbital abnormalities. This was accomplished by a thorough search of multiple databases. The findings demonstrate how well PSI works to improve both functional and cosmetic outcomes, such as the correction of facial asymmetries, enophthalmos, and diplopia. Surgical navigation and 3D printing are examples of cutting-edge technology that have improved orbital defect reconstruction's precision and versatility. While some research points to a trend toward better results when using PSI as opposed to more conventional methods, additional long-term data is required to properly assess its effectiveness. The analysis highlights the role that customized implants play in attaining the best possible outcomes and urges more research to improve surgical methods and assess patient outcomes over long time frames.

“…Numerous studies have demonstrated the efficacy of the mirroring technique (including in automated mode) in orbital reconstruction involving the application of patientspecific implants [19,20]. However, slight differences in volume between the right and left orbit were documented in a study of human skulls [21].…”

(1)The study aimed to measure the depth, volume, and surface area of the intact human orbit by applying an automated method of CT segmentation and to evaluate correlations among depth, volume, and surface area. Additionally, the relative increases in volume and surface area in proportion to the diagonal of the orbit were assessed. (2) CT data from 174 patients were analyzed. A ball-shaped mesh consisting of tetrahedral elements was inserted inside orbits until it encountered the bony boundaries. Orbital volume, area depth, and their correlations were measured. For the validation, an ICC was used. (3) The differences between genders were significant (p < 10−7) but there were no differences between sides. When comparing orbit from larger to smaller, a paired sample t-test indicated a significant difference in groups (p < 10−10). A simple linear model (Volume~1 + Gender + Depth + Gender:Depth) revealed that only depth had a significant effect on volume (p < 10−19). The ICCs were 1.0. (4) Orbital volume, depth, and surface area measurements based on an automated CT segmentation algorithm demonstrated high repeatability and reliability. Male orbits were always larger on average by 14%. There were no differences between the sides. The volume and surface area ratio did not differ between genders and was approximately 0.75.
