Summary
A novel mandibulotomy technique uses an osteotome to bicortically split the symphysis, preserving dentition and preventing malocclusion. This method ensures accurate alignment and rigid fixation for head and neck cancer surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Head and Neck Surgery
- Surgical Oncology
Background:
- Mandibulotomy is crucial for head and neck cancer surgical access.
- Traditional techniques often lead to postoperative malocclusion in patients with teeth.
- Malocclusion arises from the gap created by saw cuts during reconstruction.
Purpose of the Study:
- To introduce a modified mandibulotomy technique.
- To address and prevent postoperative malocclusion in dentate patients.
- To improve reconstructive accuracy and stability.
Main Methods:
- A novel bicortical split symphysis osteotomy using an osteotome.
- Modifications to spare healthy dentition during the procedure.
- Rigid fixation using three bone screws and a dental arch bar.
Main Results:
- Successful preservation of healthy dentition.
- Accurate approximation and alignment of hemimandibular segments.
- Stable and rigid reconstruction achieved.
Conclusions:
- The modified bicortical split symphysis mandibulotomy effectively prevents malocclusion.
- This technique offers a reliable alternative for head and neck cancer surgery in dentate patients.
- Improved patient outcomes through precise reconstruction and preserved dentition.
