Summary
This study introduces a novel mentoplasty technique using autogenous mandibular bone for chin augmentation. The procedure demonstrated satisfactory results and improved facial contours without rejection reactions.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Aesthetic Surgery
Context:
- Mentoplasty, or chin augmentation, is a common procedure in aesthetic surgery.
- Traditional methods may involve implants or alloplastic materials.
- Autogenous bone grafting offers a biological alternative for facial contouring.
Purpose:
- To evaluate a new mentoplasty technique utilizing autogenous mandibular bone.
- To assess the efficacy and safety of intraoral bone resection and fixation for chin augmentation.
Summary:
- A novel intraoral approach was used to resect prominent mandibular angle or outer lamina bone.
- Resected bone fragments were shaped and fixed to the chin using miniplates and screws.
- Thirty patients underwent this procedure, with 20 using mandibular angle bone and 10 using outer lamina bone.
Impact:
- The technique resulted in substantial improvement of facial contours.
- No adverse events, such as rejection reactions, were observed.
- Autogenous mandibular bone is presented as an ideal material for genioplasty.
