In patients who have defects on cranial bone, it is well known that reconstruction with autogenous bony material is the method of choice. However, it has limitations.; manipulation difficulty, donor site morbidity. Recently, many available synthetic materials has been developed, and their use became more common. The original cranial bone has three layers. ; outer table, medulla, inner table. Based on this finding, we performed cranioplasty in bony defect patients by composite use of Bone wax(R), Bone chip(R), Medpor(R). With this method, we could reproduce more reliable bony contour which mimic original cranial bony three layers.
