    Area of Science:

    • Oral and Maxillofacial Surgery
    • Surgical Techniques
    • Anatomy

    Background:

    • The sagittal split osteotomy is a common procedure in orthognathic surgery.
    • Variations exist to improve safety and outcomes.
    • The Dautrey modification is one such technique.

    Purpose of the Study:

    • To evaluate the safety and efficacy of the Dautrey modification of the sagittal split mandibular osteotomy.
    • To highlight critical technical aspects for successful outcomes.

    Main Methods:

    • Review of surgical procedures utilizing the Dautrey modification.
    • Emphasis on the use of wide, lateral ramus retractors.
    • Focus on the protection of neurovascular structures.

    Main Results:

    • The Dautrey modification is a safe operation when performed correctly.
    • Frequent application of the technique yields consistent results.
    • Wide, lateral ramus retractors provide essential posterior protection.

    Conclusions:

    • The Dautrey modification is a reliable surgical approach for mandibular osteotomies.
    • Adherence to technique and use of specific retractors are crucial for patient safety.
    • This method effectively safeguards major neurovascular structures.
