BACKGROUND: There is no optimal method for reconstruction of large calvarial defects. Because of the limitations of autologous bone grafts and alloplastic materials, new methods for performing cranioplasties are needed. OBJECTIVE: To create autologous bone to repair cranial defects. METHODS: We performed a cranioplasty procedure with this new method in 4 patients who had large calvarial defects of different etiologies. We used autologous adipose-derived stem cells seeded in beta-tricalcium phosphate granules. For 2 patients, we used a bilaminate technique with resorbable mesh. RESULTS: During follow-up, there were no clinically relevant postoperative complications. The computed tomography scans revealed satisfactory outcome in ossification, and in the clinical examinations, the outcomes were good. The cranioplasty was measured in Hounsfield units from each computed tomography scan. The Hounsfield units increased gradually to equal the value of bone. CONCLUSION: The combination of scaffold material such as beta-tricalcium phosphate and autologous adipose-derived stem cells constitutes a promising model for reconstruction of human large cranial defects. The success of these clinical cases paves way for further studies and clinical applications to turn this method into a reliable treatment regimen.
