Summary
Mandibular notching after bilateral sagittal split osteotomy (BSSO) causes aesthetic issues. This study reviews BSSO risk factors and introduces a novel technique to prevent mandibular contour irregularities during healing.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
- Surgical Anatomy
Background:
- Healing after mandibular osteotomy can lead to contour deformities.
- Mandibular notching compromises facial aesthetics and necessitates revision surgery.
- Bilateral sagittal split osteotomy (BSSO) is a common procedure with potential aesthetic complications.
Purpose of the Study:
- To conduct a literature review on risk factors for mandibular notching post-BSSO.
- To present an original preventative technique for mandibular contour irregularities.
- To improve aesthetic outcomes following orthognathic surgery.
Main Methods:
- Comprehensive literature search for studies on BSSO and mandibular notching.
- Analysis of identified risk factors associated with osteotomy site healing.
- Description of a novel surgical technique designed for prevention.
Main Results:
- Key risk factors contributing to mandibular notching were identified.
- The proposed technique aims to mitigate bone resorption and contour deformities.
- Evidence-based review highlights the need for preventative strategies.
Conclusions:
- Mandibular notching is a significant concern in BSSO.
- The proposed technique offers a potential solution for preventing aesthetic deformities.
- Further research and clinical application are warranted to validate the preventative technique.
