📚 Background

Zygomatico-maxillary complex (ZMC) fractures are common facial injuries that can lead to significant functional and aesthetic challenges. Traditional surgical methods may not always achieve ideal symmetry, prompting the exploration of computer-assisted surgery (CAS) as a means to enhance surgical planning and outcome evaluation.

🗒️ Study

Conducted at the Maxillofacial Surgery Unit of Siena University Hospital from 2017 to 2024, this retrospective cohort study focused on 16 patients who underwent treatment for unilateral ZMC fractures. The study aimed to assess the effectiveness of CAS in evaluating surgical outcomes and to propose a standardized workflow for future assessments.

📈 Results

The analysis revealed that CAS comparisons between post-operative outcomes and the contralateral side showed significant asymmetries, particularly in critical areas such as the fronto-zygomatic suture and zygo-maxillary points. Furthermore, CAS-optimized reductions demonstrated statistically significant improvements compared to traditional surgical methods, underscoring the challenges in achieving ideal symmetry.

🌍 Impact and Implications

The findings from this study suggest that CAS technology can significantly enhance the precision of evaluating ZMC fracture outcomes. By allowing for detailed comparisons between actual surgical results and virtual simulations, CAS has the potential to improve surgical planning and execution, particularly in complex cases. This could lead to better patient outcomes and more consistent aesthetic results in facial reconstructive surgery.

🔮 Conclusion

This study highlights the transformative potential of computer-assisted surgery in the evaluation of zygomatic fracture outcomes. By proposing a reproducible workflow and demonstrating measurable improvements in surgical precision, the research paves the way for future advancements in surgical techniques. Continued exploration of CAS, particularly with the integration of artificial intelligence, could further enhance its clinical applicability and effectiveness.
