Summary
Computer-assisted surgery (CAS) and patient-specific plates (PSP) enhance orthognathic surgery accuracy and efficiency. Global adoption varies by region and surgeon experience, with accuracy and efficiency being primary drivers.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Technology
- Surgical Planning
Background:
- Computer-assisted surgery (CAS) and patient-specific plates (PSP) offer potential improvements in orthognathic surgery.
- Traditional techniques have limitations in accuracy and efficiency.
Purpose of the Study:
- To analyze current global trends in the adoption of CAS and PSP for orthognathic surgery.
- To investigate the primary reasons for the utilization of CAS and PSP by surgeons.
Main Methods:
- A survey of 29 multiple-choice questions was distributed to AO Foundation Craniomaxillofacial e-mail subscribers.
- Data collected included preoperative workup, data collection methods, use of cutting guides and PSP, and reasons for use.
Main Results:
- 71.9% of respondents used CAS, with significant regional variations (e.g., 95.7% in North America vs. 47.4% in MENA).
- Surgeons with 10-15 years of experience were more likely to use CAS. Over half of CAS users also employed PSP.
- Primary reasons for using CAS/PSP were accuracy (79.1%), efficiency (77.5%), and ease of planning (59.3%). Most perceived CAS as faster than traditional methods.
Conclusions:
- Adoption of CAS and PSP in orthognathic surgery shows regional and experience-based disparities.
- Surgeons utilize CAS and PSP to enhance accuracy, efficiency, and minimize deviations from the surgical plan.
