Reconstruction of lateral mandibular defects with dynamic bridging plates

The principle of mandibular reconstruction by dynamic bridging plates in association with a bone graft is based on the double bridge reconstruction method. However, the plate can be used alone. Our aim was to report the long-term results of this treatment for mandibular lateral defects in fragile patients. From 1993 to 1999, 38 consecutive patients had primary reconstructions with bridging plate for lateral mandibular defects. Their mean age was 58.4 years (26-86) and the mean follow-up was 50 months (6-89). Excluding removal of plates for local recurrences, the overall success rate was 78%. Plates were removed after a mean of 20.4 months (1-66). No plates fractured. Dynamic bridging plates allow an immediate and efficient reconstruction with reduced operating time and compare favourably with conventional plates. They can also be used as a stand-by for patients who are to have a delayed free flap reconstruction.
