Summary
This study introduces a virtual surgery (VISU) tool for planning aesthetic outcomes in dento-skeletal malocclusions. The VISU tool accurately predicted surgical changes in 80% of patients, aiding in healthcare improvement.
Area of Science:
- Medical Simulation
- Computer-Aided Surgery
- Craniofacial Surgery
Background:
- Computer-based surgery simulation is vital for advancing healthcare.
- Accurate prediction of aesthetic outcomes in corrective surgery is challenging.
Purpose of the Study:
- To present a virtual surgery (VISU) tool for planning aesthetic impacts of hard and soft tissue movements in dento-skeletal malocclusions.
- To enable realistic prediction of soft tissue behavior using 3D computed tomography (CT) models.
Main Methods:
- Developed a VISU tool for direct interaction with detailed 3D CT head models.
- Simulated maxillary or mandibular osteotomies in 25 patients with facial malformations.
- Compared simulation predictions with postoperative 3D CT and clinical outcomes.
Main Results:
- The VISU tool achieved accurate predictions of surgical changes.
- In 80% of cases, simulation-predicted changes were within the 2 mm tolerance level set by surgeons.
- Demonstrated realistic prediction of soft tissue behavior.
Conclusions:
- The VISU tool offers a reliable method for planning complex craniofacial surgeries.
- Virtual surgery simulation can significantly improve the accuracy of predicting aesthetic outcomes.
- This technology has the potential to enhance patient care in maxillofacial surgery.
