Frontal bone reconstruction with split calvarial and cancellous iliac bone.

An autogenous split-thickness calvarial bone graft that was used to correct a marked depression in the frontal region of the forehead resulted in excellent cosmesis. Cancellous bone from the iliac crest, which was applied between the posterior wall of the frontal sinus and the anterior calvarial bone graft, eliminated the dead space and made infection less likely in an area prone to such infections.
