Skull or facial bone defect causes cosmetic and functional problems. On going efforts were taken to reconstruct the craniofacial bone defect with autogenous bone or alloplastic materials. Between 2001 and 2003, we reconstructed 15 cases with small to large craniofacial bone defect using Hydroxyapatite paste(BoneSource^(®), Leibinger Corp., Dallas, TX, U.S.A) and calvarial bone graft. All patients were followed up by clinical examination and periodic radiographic studies for an average of 1.6 years (range, 6 months to 2 years and 6 months). One complication case was noted with BoneSource^(®) exposure. Otherwise, there was no evidence of adverse healing, wound infection, foreign body reaction and seroma collection in other patients. Adequate 3-dimensional aesthetic restoration of calvarial contour was noted in each case. In conclusion, Bonesource^(®) is relatively safe and rigid material for craniofacial bone defect and reasonable method for the reconstruction of craniofacial bone defects.
