Asian women concerned about square faces can achieve a narrower lower face with a modified surgical technique. This approach, a modification of sagittal split osteotomy, offers stable aesthetic results for class III patients.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Aesthetic Surgery
Background:
- Prominent mandibular angles are a common aesthetic concern for Asian women.
- Class III malocclusion surgery (mandibular setback) can sometimes widen the lower face, which is undesirable in Asian aesthetics.
- Achieving a balanced facial contour often requires addressing mandibular width simultaneously.
Purpose of the Study:
- To present a modified Hunsuck technique for sagittal split osteotomy.
- To detail a surgical procedure for simultaneous mandibular contouring and setback.
- To evaluate the aesthetic outcomes and stability of this modified technique for achieving a desirable mandibular outline.
Main Methods:
- Modification of the Hunsuck technique for sagittal split osteotomy.
- Simultaneous mandibular setback and contouring to reduce lower facial width.
- Surgical procedure detailed for achieving a refined mandibular shape.
Main Results:
- The modified technique allows for reduction in lower facial width.
- A desirable mandibular outline was achieved in the studied patients.
- The long-term stability of the modified technique is comparable to traditional methods.
Conclusions:
- The modified Hunsuck technique offers a viable surgical option for Asian patients with class III malocclusion and prominent mandibular angles.
- This approach addresses aesthetic concerns regarding lower facial width, providing improved outcomes.
- The procedure demonstrates comparable long-term stability to conventional techniques.
