Abstract
An Omnipulse holmium-yttrium aluminum garnet (YAG) laser was used to assist in the harvesting of outer table or split calvarial bone grafts in cadaver skulls. Two- or 4-mm depth and 0.55-mm width holes in the outer cortex of cadaveric calvarium were formed without apparent gross periosteal or bony injury. Osteotomes were then used to shave or split calvarial grafts by connecting the 2- and 4-mm depth holes, respectively. The procedure was efficient as well as precise. We believe that this method of bone graft harvesting may have the added benefit of safety by decreasing the incidence of inadvertent dural penetration. This study will lead to further analysis of the potential use for additional bony work with the Omnipulse holmium-YAG laser.
