Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthognathic Surgery
  • Surgical Innovation

Background:

  • Sagittal split mandibular ramus osteotomy (SSRO) is a key procedure for correcting jaw deformities like prognathism and retrognathism.
  • Internal rigid fixation is commonly employed with SSRO, enhancing stability.
  • Potential complications include inferior dental neurovascular bundle injury and unfavorable mandibular fractures.

Purpose of the Study:

  • To introduce a technical modification for the sagittal split mandibular ramus osteotomy.
  • To present an innovative instrumentation concept.
  • To reduce the incidence of surgical complications associated with SSRO.

Main Methods:

  • Description of a modified surgical technique for SSRO.
  • Introduction of novel instrumentation designed to aid the osteotomy.

Related Experiment Videos

  • Focus on techniques to protect the inferior dental neurovascular bundle.

    • Main Results:

    • The proposed modification aims to enhance safety during SSRO.
    • The instrumentation concept is designed for improved control and precision.
    • Anticipated outcome is a reduction in neurovascular injury and fracture complications.

    Conclusions:

    • The modified SSRO technique and instrumentation offer a potential solution to mitigate known surgical risks.
    • This approach may improve the predictability and safety of orthognathic surgery.
    • Further clinical evaluation is warranted to validate the efficacy of the proposed modifications.
