Reimplantation of freeze-treated bone in immediate reconstruction of the mandible.

Surgical defects encountered with corrective surgery of the mandibular complex have been repaired most successfully with autogenous composite bone grafts. Their use belies inherent consequences associated with distant donor sites. Presented here are the experiences and results in two patients whose reconstructions consisted of immediate replacement of the resected mandibular segment after its devitalization with cryogenic freezing treatments. Such treated, autologous bone provides an ideal anatomic graft, nondistinct antigenicity, and immediate restoration of form and function. Monitoring of neoosteogenesis was performed with sequential panographic, nuclear, and histologic studies that documented clinical and histologic repair.

Rhinomaxillary phycomycosis: report of case.

A case of rhinomaxillary phycomycosis has been reported. Although the occurrence of the phycomycetes-type of infection is relatively rare, the oral and maxillofacial surgeon should be alert for debilitated patients, especially uncontrolled diabetics, who may show the incipient signs and symptoms of this opportunistic fungal disease.

Surgical recontouring of a panfacial fibro-osseous deformity.

A report of the surgical management of a patient with a panfacial fibro-osseous deformity resulting from fibrous dysplasia, hyperparathyroidism, or both, is presented as a sequel to a previous article discussing the initial work-up and diagnostic considerations. The literature pertinent to the surgical correction of fibro-osseous lesions irformed through an oral approach. Regrowth of the lesion after three years was minimal in the maxilla and approximately 20% in the mandible.
