Piezoelectric surgery--primary bone grafting in craniofacial trauma revisited

Reconstruction of the frontal bar following complex craniofacial fractures involving the frontal sinus is a central strategic element, and inaccurate reduction can result in contour defects and non-union. Such defects can be reconstructed using autogenous bone from the inner table of a calvarial graft. Traditionally this is done with rotary instruments and osteotomes. In this article, we describe the use of piezoelectric surgery to harvest the graft. This technique allows for more precise and less destructive harvesting of autogenous bone with the additional benefit of reducing the risk of injury to the surgeon.
