REUSE OF TUMOROUS CALVARIAL BONE AFTER GAMMA-IRRADIATION

Reconstruction of calvarium after tumor resection may present several technical difficulties. The authors reused the resected calvarial bone in four patients after submitting the bone to a lethal dose of gamma radiation. The authors conclude that resected, irradiated, tumorous bo ne can be reused for the reconstruction of its own defect. This provid es a simple method of reconstruction. Partial bone resorption should b e anticipated but further reconstruction, if needed, will be facilitat ed.
