We report a case of cranial reconstruction using autologous split calvarial bone combined with calcium phosphate bone cement (CPC). A 19-years-old man suffered from cranium defect and rhinorrhea originating from frontal skull base fracture in a traffic accident. After CSF hydration treatment had finished, continuously we performed cranial reconstruction with autologous split calvarial bone so that the patient could return to work at an early stage. The use of autologous split calvarial bone with CPC was able to increase stability of the construct and provide excellent cosmetic result in our short follow up period. The combination use of these two materials may be useful for cranial reconstruction in patients with cranium defect.
