Three-dimensional osteotomy planning in maxillofacial surgery including soft tissue prediction

Area of Science:

• Craniomaxillofacial surgery
• Medical imaging
• Surgical planning

Background:

• Preoperative planning is crucial for complex osteotomies in craniomaxillofacial surgery.
• Predicting soft tissue changes after facial bone movement remains a challenge.
• Current planning often relies solely on bony structures, neglecting aesthetic contributions of soft tissues.

Purpose of the Study:

• To introduce and evaluate a novel 3-D planning approach for craniomaxillofacial surgery.
• To integrate both surface and volumetric models for enhanced preoperative simulation.
• To assess the correlation between simulated outcomes and actual postoperative results.

Main Methods:

• Development and application of a new 3-D planning software.
• Utilizing both three-dimensional (3-D) surface models and corresponding volumetric models of patient anatomy.
• Clinical application in the treatment of 15 patients undergoing complex osteotomies.

Main Results:

• The 3-D planning software demonstrated a good correlation between preoperative simulation and postoperative outcomes.
• The combined use of surface and volumetric models improved the predictive capability.
• Successful application in a cohort of 15 patients.

Conclusions:

• The novel 3-D planning approach, incorporating surface and volumetric models, enhances the accuracy of craniomaxillofacial surgery.
• This method offers improved prediction of surgical outcomes compared to traditional techniques.
• Further adoption of this technology can lead to more predictable and optimal aesthetic results in complex facial reconstructions.
