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 bone can be reused for the reconstruction of its own defect. This provides a simple method of reconstruction. Partial bone resorption should be anticipated but further reconstruction, if needed, will be facilitated.
