Summary
Unfavorable fractures during sagittal ramus split osteotomy, though rare, can be predicted by thin mandibular rami or high lingula anatomy. A modified surgical technique helps prevent these fractures in at-risk patients.
Area of Science:
- Oral and Maxillofacial Surgery
- Anatomical Risk Factors in Osteotomy
- Surgical Technique Modifications
Background:
- Unfavorable fractures of the proximal fragment during sagittal ramus split osteotomy occur in 3-6.6% of cases.
- Thin mandibular rami and a high-situated lingula are identified anatomical risk factors.
- These anatomical variations can lead to osteotomy in thin bone regions with limited cancellous bone.
Purpose of the Study:
- To present a modified sagittal split osteotomy technique.
- To address and mitigate the risk of unfavorable fractures in patients with specific anatomical predispositions.
Main Methods:
- Description of a modified sagittal split osteotomy technique.
- Focus on adapting the osteotomy to anatomical variations like thin rami or high lingula.
Main Results:
- The presented technique aims to prevent unfavorable fractures.
- It provides a method to manage cases with challenging anatomy.
Conclusions:
- A modified surgical approach can effectively prevent unfavorable fractures during sagittal ramus split osteotomy.
- Surgeons can utilize this technique when encountering thin mandibular rami or high lingula anatomy.
