Changes in Volume and Bone Density of Calvarial Grafts After Two Years of Orbital Reconstruction.

One of the greatest challenges in orbital reconstruction is to obtain adequate orbital volume and globe projection after traumatic injury. Autologous bone graft has been considered the gold standard for orbital floor reconstruction, but the harvesting yields many possible complications, such as donor site morbidity. Bone resorption is a frequent problem that can lead to insufficient volume after graft placement.
