Life-size, computer-generated skull replica to assist surgery of craniofacial fibrous dysplasia

Craniofacial fibrous dysplasia is a benign pathological condition but it replaces bone and expands gradually, leading to facial distortion. Surgery is the only effective treatment. The authors describe the usefulness of a life-size, computer-generated skull replica which assists surgeons pre- and intraoperatively. Surgery can be safely performed with less invasion and a shorter operation time by referring to the skull replica. Partial bone resection and bone contouring have been carried out, assisted by skull replicas, in 8 patients with craniofacial fibrous dysplasia, resulting in good cosmesis.
