1Dept. of Oral and Maxillofacial Surgery, University Hospital, Nijmegen, The Netherlands.
Summary
A modified mandibular osteotomy allows anterior jaw rotation and elongation without bone grafts. This technique reduces risks to the alveolar nerve and enhances surgical stability.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
Background:
- Mandibular osteotomies are crucial for correcting jaw deformities.
- Traditional methods for anterior mandibular elongation and rotation often require bone grafting and carry risks.
Purpose of the Study:
- To present a modified osteotomy technique for mandibular body manipulation.
- To evaluate the feasibility of achieving anterior mandibular elongation and rotation without bone grafting.
Main Methods:
- A novel surgical modification of the mandibular body osteotomy was developed.
- The technique focuses on enabling specific movements of the anterior mandibular segment.
Main Results:
- The modified osteotomy facilitates anterior mandibular elongation and rotation.
- This approach eliminates the need for bone grafting.
- It demonstrates a reduced risk of alveolar nerve injury and improved surgical stability.
Conclusions:
- The presented mandibular osteotomy modification offers a viable alternative for anterior jaw repositioning.
- It enhances patient safety and surgical outcomes by avoiding bone grafts and protecting the alveolar nerve.
