A case of mandibular ameloblastoma in a patient undergoing reconstruction with particulate cancellous bone and marrow of the tibia

Abstract

We report a case of ameloblastoma of the mandible reconstructed with particulate cancellous bone marrow (PCBM) harvested from the tibia after the marginal resection of the mandibular bone. The patient was a 74-year-old woman who presented with left mandibular expansion, with no spontaneous pain. Panoramic radiography and computed tomography revealed a radiolucent lesion in the left side of the mandible. A preoperative biopsy resulted in a diagnosis of ameloblastoma. We performed marginal mandibular resection and reconstructive surgery using PCBM from the left tibia with a titanium plate and mesh under general anesthesia. We could harvest a sufficient amount of cancellous bone from the right tibia. The postoperative course was uneventful, with no complications. Reconstruction using PCBM may be an effective alternative procedure for repairing defects of the mandible.
