Bone Graft Harvest For Orbital Floor Defects

Autogenous bone grafts are the gold standard for reconstruction of maxillofacial defects. Autogenous bone becomes osseointegrated and vascularized at its site of implantation, which decreases the chances of infection, displacement, and foreign body reaction compared with alloplastic implants. The drawbacks are the harvest time, donor site morbidity, graft resorption, modeling changes, and harvest volume limitations. Autogenous bone can be harvested from multiple sites, including the calvarium, tibia, anterior ileum, posterior ileum, rib, sternoclavicle, zygoma, mandible, and so forth. The use of calvarial bone grafts (CBGs) was first reported in 1670, when Van Meekren reconstructed a Russian soldier's calvarial defect utilizing a CBG from a dog.
