Reconstruction of large mandibular and surrounding soft-tissue defects using distraction with bone transport.

Reconstruction of large bone and soft-tissue defects of the inferior third of the face is possible using various surgical techniques. Patients who require these procedures need to be in good general health, may have sequelae linked to donor sites, and require several interventions to achieve good aesthetic and functional results. The aim of this study was to report outcomes in patients with large mandibular and soft-tissue defects treated using osteogenic distraction with bone transport. Between 2001 and 2008, 14 patients had distraction with bone transport. Most patients were men (92.1%). The mean age was 43.1 years. The average mandibular bone reconstruction was 13.6 cm. The mean duration of distraction was 2.3 months. No infections occurred, and in all cases reconstruction of soft tissues was obtained. Two patients had non-union and underwent reconstruction using an iliac bone graft. Patients with sufficient bone height (57.1%) had dental implants. 44 implants were inserted, two of which were lost. 36 implants were activated. Six patients had satisfactory oral rehabilitation with implant-supported prostheses. Osteogenic distraction with bone transport allows total or partial restoration of oral function, provides an acceptable appearance, and enables patients to resume a reasonable quality of life.
