[Background and Objectives]
Recent advancements in digital workflow integration in orthognathic surgery have shown promising results in improving planning precision and surgical outcomes. This study aims to enhance the efficiency and accuracy of orthognathic surgery by incorporating cloud-based telemedicine and extended reality (XR) technology within the digital workflow.

[Methods]
A retrospective analysis was conducted on 69 patients (15 males, 54 females, average age 29 years 7 months) who underwent orthognathic surgery at Mirise Clinic Minamiaoyama£¨Tokyo,Japan£© from January 2022 to June 2024. In this study, a comparative analysis and patient questionnaires were conducted to superimpose surgical planning using preoperative 3D simulation, CAD/CAM technology, and XR technology on actual surgical results.

[Results]
All patients were discharged within 24 hours post-surgery with no complications reported. The surgical duration ranged from 3 hours 18 minutes to 6 hours 18 minutes, with an average of 4 hours 1 minute. Patient surveys indicated that 31% returned to society within 4-6 days, 28.6% within over 14 days, 21.4% within 7-13 days, 14.3% within 2-3 days, and 4.8% the next day. Surgeries using these digital workflows were not only more accurate, but also resulted in higher overall patient satisfaction, with an average score of 8.9 out of 10.

[Discussion]
The integration of digital workflow and XR technology significantly improved surgical efficiency and accuracy. The use of 3D holographic models with XR technology was particularly beneficial for preoperative planning and intraoperative guidance, potentially reducing postoperative complications. Additionally, digital technology proved effective in providing psychological care for patients, enhancing their overall recovery experience.

[Conclusion]
The integrated digital workflow with cloud-based telemedicine and XR technology significantly enhances the planning and outcomes of orthognathic surgery, improving patient quality of life. Future research should focus on long-term data collection from a larger patient cohort to further validate these findings.
