Autogenous Cranial Bone Grafts for Treating Oral and Maxillofacial Deformity / 中国医师杂志

ABSTRACT

Objective To evaluate the effect of the autogenous split-thickness cranial bone grafts on treatment of deformity of oral and maxillofacial regions. Methods The split-thickness cranial bone was harvested through the coronal incisions or the parietotemporal region incisions. The bone graft was then fashioned to the appropriate size and configuration and fixed to the regions of defects and deformities. The cranial bone was used to reconstruct facial bone framework or as sustaining bone graft for facial augmentation. Results 31 patients with the oral and maxillofacial deformities or bone defects were repaired with the cranial bone grafts, including 17 cases of orbital floor defects, 6 cases of malunion of the zygoma fractures, 5 cases of secondary deformity after ankylosis of temporomandibular joint, 2 cases of bone reconstruction after tumor resection and 1 case of cleft palate deformity. The followed-up period ranged from 6 months to 7 years, averaging 11 months. There were no complications of infection and extrusion, no obvious bone resorption was observed, and the facial appearance were greatly improved. Only one patient had a small ectropion which persisted three months. After six-month, the ectropion was not obvious. Conclusion Autogenous bone grafts used to reconstruct the defect and deformity of oral and maxillofacial regions can reduce the risks of infection and extrusion, and there is less visible scar and less bone resorption. Skull bone is an ideal source of bone graft material in the oral and maxillofacial deformity.
