BACKGROUND: The goal of cranioplasty is to achieve a lifelong, stable and structural reconstruction of the cranium covered by a healthy skin and scalp flap. We present two cases of large frontal bone defect following a accident.. CASES: We describe the utilization of autogenous local split calvarial graft and titanium mesh for the reconstruction of the post trauma frontal bone defect.CONCLUSION: Cranioplasty using split calvarial bone grafting for restoring large cranial defects resulting from a trauma is a useful technique, and allows the surgeon to reconstruct a moderate to large cranial defect without rifting the inner cortical plate.
