Summary
This study introduces modified sagittal split ramus osteotomy techniques using new instruments and a reciprocating saw. These advancements aim to enhance safety and speed in mandibular ramus osteotomies for improved surgical outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
Background:
- Sagittal split ramus osteotomy (SSRO) is a common procedure in orthognathic surgery.
- Traditional SSRO techniques carry risks of neurovascular injury and procedural complications.
Purpose of the Study:
- To present a modified SSRO technique utilizing novel instrumentation.
- To evaluate the safety and efficiency of the modified SSRO procedure.
Main Methods:
- A modified SSRO approach employing a reciprocating saw and new retractors (wide-blade buccal and lingual) was developed.
- The technique follows Dal Pont's osteotomy line, emphasizing precise saw blade direction to protect the inferior alveolar neurovascular bundle.
- The modified instruments facilitate clear visualization and protection of soft tissues.
Main Results:
- The modified technique allows for sagittal separation of the ramus using a reciprocating saw.
- The use of specialized retractors enhances protection of adjacent soft tissues and neurovascular structures.
- The procedure results in a smooth osteotomized interface, aiding bone segment repositioning.
Conclusions:
- The modified sagittal split ramus osteotomy with new instruments and a reciprocating saw offers a potentially safer and faster alternative.
- This technique may reduce the risk of intraoperative complications associated with SSRO.
- Further clinical studies are warranted to validate the long-term efficacy and benefits.
