ABSTRACT
External decompression was performed on four patients with head trauma and one patient with meningioma. Cranioplasty was done for correcting sknll defeets in these parients later using. Eight ceramic bones. Ceramic bones were made on 3-dimenssional solid models with cranial defects reconstructed based on data of computed tomography scan. The artifical bones conformed to the acutual cranial defects perfectly. Ceramic bone was thought to be suitable for correcting big cranial defects in cosmetic respects. Two complications were observed in these patients during the average follow-up period of ten months. One complication case was infection of artificial bone, and the other was post-operative epidural hematoma. When the size of articial bone was big or the shape of that was strongly curved, we had to pay attention to the tacking of dura during operation.
