Summary

Temporary external fixation aids mandibular reconstruction with vascularized bone grafts, ensuring proper alignment without plates. This method is especially useful for tumors affecting the mandible

Area of Science:

  • Oral and Maxillofacial Surgery
  • Reconstructive Surgery
  • Biomedical Engineering

Background:

  • Mandibular defects often require complex reconstruction.
  • Vascularized bone grafts are crucial for restoring mandibular function and form.
  • Achieving optimal alignment and stability during reconstruction is challenging.

Purpose of the Study:

  • To evaluate the utility of a temporary intraoperative external fixation device.
  • To assess its role in optimizing bony reconstruction of the mandible using vascularized bone grafts.

Main Methods:

  • Retrospective review of six patients undergoing mandibular composite resection and reconstruction.
  • Utilized an intraoperative external fixation system to guide vascularized bone graft (scapula or fibula) placement.

  • Follow-up ranged from 2 to 16 months.

    • Main Results:

    • All six patients achieved successful mandibular reconstruction.
    • Key outcomes included acceptable facial contour, dental occlusion, and condylar positioning.
    • A single complication involved a postoperative cerebrovascular accident necessitating anticoagulation and resulting in a neck hematoma.

    Conclusions:

    • Intraoperative external fixation effectively maintains mandibular segment alignment.
    • This technique obviates the need for a bridging reconstruction plate.
    • It is particularly advantageous for reconstructions involving tumors of the mandibular outer cortex.
