Frozen autogenous mandible as an immediate replacement graft.

A study in animals was designed to examine the feasibility of grafting autogenous frozen mandible. Two groups of animals were used. In the first group, periosteum was elevated from the bone before resection. In the second group, the periosteum was removed with the resected specimen. Osteogenesis was shown by clinical, radiographic, fluorescence, and histologic studies in both groups of animals. The same technique was performed in nine humans with carcinomas that involved the mandible. The results were encouraging. We believe that immediate or delayed reconstruction with autogenous frozen mandible in a patient undergoing ablative surgery of the head and neck with involvement of the bone may offer the patient, as well as the surgeon, another acceptable treatment modality.
