Summary
This study presents a novel surgical technique using trigonometric formulas for correcting midfacial deformities. The modified oblique Le Fort III osteotomy improves facial aesthetics and airway function with accurate, reproducible results.
Area of Science:
- Maxillofacial Surgery
- Orthognathic Surgery
- Craniofacial Reconstruction
Background:
- Midfacial deformities, including vertical excess and posteroanterior hypoplasia, present complex challenges in surgical correction.
- Oblique movements of the midface complex are necessary to address these deformities, improve lip competence, and enhance malar projection.
Purpose of the Study:
- To demonstrate a surgical technique for correcting midfacial deformities using a modified oblique Le Fort III osteotomy.
- To introduce a mathematical formula for calculating the precise angulation required for simultaneous vertical and posteroanterior midface movement.
- To provide maxillofacial surgeons with an accurate, reproducible, and affordable method for treating midfacial deformities.
Main Methods:
- The study involved patients treated with Modified Oblique Le Fort III osteotomies between February 2013 and November 2014.
- Two trigonometric formulas were applied to ensure accuracy in the surgical technique.
- Custom surgical guides, based on stereolithographic models and calculated angulations, were utilized during operations.
Main Results:
- The application of the trigonometric formulas resulted in accurate surgical corrections.
- The technique led to a noticeable enlargement of the upper airway.
- Significant improvements in the esthetic outcomes for patients were observed.
Conclusions:
- The Modified Oblique Le Fort III osteotomy, guided by trigonometric formulas, offers an accurate and reproducible method for correcting midfacial deformities.
- This technique enhances both functional aspects, such as airway volume, and esthetic results.
- The described approach expands the surgical options available for treating complex midfacial skeletal discrepancies.
