ABSTRACT
Introduction: The autologous options for reconstruction of the skull defects stand out for their better integration.
Method: Case report. Extensive cranial defect due to trauma. We exemplify the effectiveness of parietal bone bipartition.
Result: Defect with an approximate size of 120 cm2 in the right parietal region. Contra-lateral parietal craniotomy was performed to obtain the donor bone by bipartition. Osteosynthesis of the donor and recipient area with 1.2 mm titanium miniplate and screw system. The procedure was performed in an approximate time of 3 hours, without need of blood transfusion and with adequate closure of the cranial defect.
Conclusion: The success of the technique used is due to the better stability in fixation and excellent tissue compatibility. The use of autologous grafts is associated with a lower rate of complications. The major defects of the skull do not need to be treated with synthetic prostheses if we can reconstruct with autologous grafts.
