title: Dacron mesh tray and cancellous bone in reconstruction of mandibular defects.
abstract: We used a Dacron-urethane mesh tray filled with cancellous bone for mandibular reconstruction in 17 patients. Five patients with traumatic defects and two with benign tumors developed solid, functional mandibles. Among ten patients with squamous cell carcinoma, eight had successful reconstruction; one required a second procedure. Mandibles of two of three patients with osteoradionecrosis were successfully reconstructed, but only one of three primary reconstructions was initially successful. The Dacron-urethane mesh tray has the advantage of being stiff but malleable. It easily fits the defect, is radiolucent, and may be used either before or after radiotherapy. We recommend delayed reconstruction, adequate soft-tissue coverage, good immobilization of the mandible, no intraoral contamination, especially with osteoradionecrosis, and hyperbaric oxygen in patients who have been irradiated or have osteoradionecrosis.
