Precision and Efficacy of Digital Technology in Orthognathic Surgery for Facial Asymmetry Correction: A Quantitative Analysis

Area of Science:

• Oral and Maxillofacial Surgery
• Digital Imaging
• Surgical Planning

Background:

• Facial asymmetry presents complex challenges in orthognathic surgery.
• Accurate surgical planning is crucial for achieving optimal aesthetic and functional results.
• Digital technology offers potential for enhanced precision in complex surgical procedures.

Purpose of the Study:

• To evaluate the efficacy of digital technology-assisted design in orthognathic surgery for patients with facial asymmetry.
• To assess the three-dimensional consistency between preoperative digital simulations and postoperative outcomes.

Main Methods:

• Thirty patients with facial asymmetry underwent orthognathic surgery planned with digital technology (Mimics software).
• Surgical guides were created based on digital simulations.
• Three-dimensional consistency was evaluated by comparing preoperative designs with postoperative cranial models using reference planes and measuring landmark distances.

Main Results:

• No significant differences were found between digital simulations and postoperative models.
• Postoperative landmark discrepancies were within 1 mm.
• Seventy-five percent of asymmetry indicators improved to less than 10%, with a mean pogonion to midsagittal plane distance of 1.82 mm.

Conclusions:

• Digital technology-assisted design enhances operative precision in orthognathic surgery for facial asymmetry.
• This technology leads to favorable treatment outcomes and improved effectiveness.
