Orbitocranial Fibrous Dysplasia: Immediate Reconstruction with Titanium 3-dimensional Printing

We present the case of an 18-year-old man who was referred to our department with a suspected tumor in the right orbital region, which caused exophthalmos due to its pressure effect. Preoperative CT imaging revealed an expansile ground-glass appearance of bone mass, with sclerotic bone on the right frontal bone (right superior orbital wall). There was no orbital mass and no enlargement of the extraocular muscles and tendons; the retrobulbar fat and optic nerve appeared unremarkable. A preoperative tissue biopsy confirmed the FD. Complete tumor removal was performed via the right hemicoronal approach. The orbital roof and temporal bone defect were immediately reconstructed using the 3-dimensional titanium printing plate.
