title: Reconstruction of the mandible.
abstract: Forty-five patients were evaluated for reconstruction of the mandible. Thirty-four patients had a particulate cancellous bone and marrow (PCM) crib graft placed. Thirty of 34 were successful at the primary operation producing a success rate of 88%. By using secondary procedures all 33 patients repaired to date have been rehabilitated. A dynamic bendable defect bridging plate with cancellous cortical graft (DBDB plate with CCG) was used in 7 patients, 4 of whom had tumor surgery and 3 of whom were operated on after trauma to the anterior mandible. All 7 cases were successfully rehabilitated in achieving a stable, functioning mandibular arch. An osteomyocutaneous flap was planned to reconstruct the anterior mandible in 4 cases; 1 in this group was not reconstructed. The PCM graft has been our first line approach to the mandibular non-union but with experience we are beginning to rely on the DBDB plate with CCG for large bony defects after both trauma and secondarily after tumor surgery. When indicated, the osteomyocutaneous flap has been eminently successful in restoring function and form in the tumor patient.
