Vascularized fibular flap for reconstruction of the condyle after mandibular ablation.

PURPOSE: The purpose of this study was to evaluate the outcome of the vascularized fibular free flap for the reconstruction of mandibular resections involving the condylar segment.

PATIENTS AND

METHODS

Six patients underwent mandibular resection including the condyle. Two patients were diagnosed with squamous cell carcinoma, whereas the other 4 presented fibrous dysplasia, mandibular osteoradionecrosis, mandibular ameloblastoma, and giant cell granuloma of the mandible. All of them underwent condylar reconstruction by means of transplant of the free fibular flap. In all the cases, the fibula was placed directly into the glenoid fossa. The temporomandibular disc was preserved over the pole of the fibula. Panoramic radiographs were performed postoperatively to evaluate condylar position and grade of bone resorption.

RESULTS

Five patients developed adequate temporofibular function with absence of hypomobility and optimum interincisal opening, whereas 1 patient developed a temporofibular ankylosis with severe limitation of mandibular mobility and mouth opening.

CONCLUSIONS

The use of the fibula flap directly fitted into the glenoid fossa constitutes a reliable method in condylar reconstruction. However, the possibility of severe complications such as ankylosis has to be considered.
