Background: The management of fronto-orbital fibrous dysplasia involves total excision of the dysplastic bone and bone reconstruction using implants. Custom-made implants are used to achieve good contouring. However, the remnant defect after excising the lesion often does not match the implant. Methods: To design the craniotomy line, a template was prepared by preoperative computed surgical simulation. The template was overlaid on the preoperative cranium, such that its inner surface fits exactly with the cranial surface. After excising the lesion by performing osteotomy, the implant was placed in the defect and fixed. Both template and implant were made of hydroxyapatite. Results: The authors treated 4 patients, with fibrous dysplasia involving the fronto-facial region by using the template. Intraoperative trimming of the implant or bone defect was not required in 2 patients, while the third patient required mild trimming. They did not have any complications and obtained good contouring. Conclusion: The hydroxyapatite templates reduced the surgical time by determining the precise craniotomy line preoperatively, thus avoiding needless trimming of the implant and bone defect. Therefore, they can enhance the efficacy of treatment for fronto-orbital fibrous dysplasia lesion.
