Fibrous dysplasia refers to a chronic bone deformity caused by abnormal fibrotic and osseous tissue replacing normal ones. Craniofacial fibrous dysplasia can lead to facial asymmetry, which can cause misalignment of jaw, nasal airway congestion, proptosis, and vision loss. To improve facial asymmetry and preserve optic nerve function, operation is indicated. However, pathological bone at the affected ocular area can be really close to the optic nerve. Complicated and limited surgical field increased operation difficulty. Thus, precise operation is required for minimizing risk of optic nerve injury. Navigator-assisted surgery can be applied to these patients with optic nerve compression. In addition, we proposed integrating three-dimensional computer simulation into preoperational planning in navigator-assisted surgery to improve precision. Here, we present a case diagnosed as craniofacial dysplasia undergoing navigator-assisted surgery with integration of computer simulation. |
