Intraosseous wiring in ramus osteotomy.

P Astrand, O Eckerdal, G Sund

    Journal of Oral and Maxillofacial Surgery : Official Journal of the American Association of Oral and Maxillofacial Surgeons
    |December 1, 1983

    Summary

    Intraosseous wiring after mandibular ramus osteotomy showed minimal benefit. In most prognathism cases, this wiring technique is not essential for stable outcomes.

    Area of Science:

    • Oral and Maxillofacial Surgery
    • Orthognathic Surgery
    • Surgical Stabilization Techniques

    Background:

    • Oblique osteotomy of the mandibular rami is a common procedure in orthognathic surgery.
    • The necessity of intraosseous wiring for fragment stabilization after this osteotomy is debated.
    • Effective stabilization is crucial for predictable surgical outcomes and minimizing relapse.

    Purpose of the Study:

    • To evaluate the efficacy of intraosseous wiring in stabilizing mandibular fragments after oblique osteotomy.
    • To compare cephalometric changes between patients with and without intraosseous wiring.
    • To determine if intraosseous wiring is necessary in routine cases of mandibular prognathism.

    Main Methods:

    • A comparative study involving two groups of patients undergoing oblique osteotomy of the mandibular rami.
    • One group (14 patients) received intraosseous wiring for fragment fixation.
    • The second group (15 patients) did not receive wiring, serving as a control.
    • Cephalometric analysis was performed to assess postoperative mandibular position and rotation.

    Main Results:

    • Minor cephalometric differences were observed between the wired and nonwired groups.
    • A slight trend towards reduced posterior rotation of the mandible was noted in the wired group post-surgery.
    • These differences were not statistically significant enough to indicate a substantial clinical advantage for wiring.

    Conclusions:

    • Intraosseous wiring of fragments following oblique osteotomy of the mandibular rami offers minimal additional benefit in routine cases.
    • The routine use of intraosseous wiring may not be necessary for achieving stable results in mandibular prognathism correction.
    • Surgeons can consider omitting intraosseous wiring in standard procedures, potentially simplifying the surgical process.
