Abstract

Our preferred technique for mandibular reconstruction uses a revascularized osseomyocutaneous flap. However, to reconstruct small lateral defects in dentulous patients, the AO mandibular reconstruction plate (MRP) is used. Its advantages include quick, reliable placement without a donor site or the need for advanced technical training.

This review examines 16 patients who underwent primary mandibular reconstruction after ablative oncologic surgery using an AO MRP without a bone graft. The average follow-up was 32 months. Twelve patients (75%) had successful reconstructions, while 4 (25%) developed serious complications resulting in failure of the MRP. The most significant factor limiting rehabilitation was disease progression, affecting 12 (75%) of the 16 patients.

In this subgroup of selected patients with small (<6 cm) lateral mandibular defects, useful dentition, and advanced disease, or whose general medical condition precludes prolonged general anesthesia, primary mandibular reconstruction using an AO MRP and a myocutaneous flap without a bone graft is a viable reconstructive alternative.
