Prospective will be collected in a minimum of 300 patients presenting with an acquired segmental mandibular defect ≥ 2 cm secondary to OSSC removal and drugs-induced osteonecrosis, and who require mandibular reconstruction.
Data will be prospectively collected from at least 300 patients with acquired segmental mandibular defects of 2 cm or larger following resection of tumors or necrotic/infected tissue, all of whom require mandibular reconstruction. The follow up (FU) will consist of standard of care (routine) procedures and data collection will be done at 3, 6, 12, 18 and up to 24 months after resection and/or reconstruction. The maximum FU for each patient within the registry will be 2 years after mandibular resection. Data collection will include confounding baseline data, tumor characteristics, neurologica…
Inclusion Criteria: * The study includes patients with an initial pathological/histologic diagnosis of mandibular involvement by oral tumors (such as OSCC, osteosarcoma, and ameloblastoma), bisphosphonate- or immunomodulatory drug-induced osteonecrosis, and mandibular lesions from metastatic conditions originating from other sites including lung, breast, prostate, or kidney. * Age 18 years and older * Bisphosphonate related osteonecrosis of the mandible * Immunomodulatory drugs induced mandibular osteonecrosis * Patients presented with ameloblastoma affecting the mandible * Patients presented…
One stage reconstruction: Osseous reconstruction is performed in the same surgery of the tumor/mandibular resection. It is also known as immediate or primary reconstruction. Second stage reconstruction: Osseous reconstruction is performed after the tumor/mandibular resection surgery as an independent surgery. After the mandibular resection a temporary alloplastic bridging might be put in place. It is also known as delayed or secondary reconstruction.
