Harvesting cranial bone grafts

There are several types of calvarial bone grafts that may be taken:
Shaved corticocancellous outer table graft with attached pericranium
These small grafts are taken with a sharp osteotome after scoring their outlines with a side-cutting burr or by direct tangential cutting off a bone convexity with a reciprocating or oscillating saw. The resulting bone splinters are held together by the pericranium left on the surface. The thin grafts will curl and are malleable within certain limits.
