Experience With Segmental Reconstruction of the Radiated Mandible With Alloplastic Prostheses

Reconstruction of the mandible after radiation therapy and segmental resection is often complicated by wound breakdown, osteoradionecrosis, and crippling of the oral cavity. These complications make patient salvage after radiated oral carcinoma a high-risk endeavor. Although head and neck surgeons have improved the reliability of mandibular reconstruction with microvascular free tissue transfer, medical and oncologic issues may prohibit their application. This report presents 12 selected cases undergoing alloplastic reconstruction of the mandible and soft tissue reconstruction of the oral cavity. Although not as reliable as some reports of free tissue transfers, the results were reproducible and satisfactory in these cases, with time-efficient hospitalization and functional rehabilitation. Ten of 12 prosthetic reconstructions have been durable in this study population for as long as 36 months.
