The AO/ASIF reconstruction plate effectively stabilizes mandibular defects after cancer surgery. This technique ensures successful reconstruction with good function and cosmetic outcomes for patients.

Area of Science:

Oral and Maxillofacial Surgery
Surgical Oncology
Biomaterials Engineering

Background:

Primary reconstruction of mandibular segmental defects after cancer resection presents significant challenges.
The AO/ASIF (Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation) developed a stainless steel plate in 1976 for mandibular reconstruction.

Purpose of the Study:

To evaluate the efficacy and outcomes of using the AO reconstruction plate for primary mandibular reconstruction following cancer resection.

Main Methods:

The AO reconstruction plate was utilized in six patients undergoing composite resection for mandibular defects.
The technique focused on stabilizing mandibular stumps without requiring intermaxillary or external fixation.
The plate's design was noted to promote revascularization in bone grafting procedures.

Main Results:

The reconstruction plate technique did not compromise the extent of cancer resection.
Operating time was not excessively prolonged, and postoperative management remained unaltered.
All six patients successfully retained the AO reconstruction plate, achieving satisfactory functional and cosmetic results.

Conclusions:

The AO reconstruction plate is a reliable method for primary mandibular reconstruction after cancer resection.
This technique offers successful functional and cosmetic restoration with stable fixation.
The plate's design facilitates bone graft revascularization, enhancing reconstruction outcomes.
