Surgery improves vision and cosmetic appearance of an adult patient with fibrous dysplasia of the frontal bone.

Abstract A 31-year-old woman with fibrous dysplasia (FD) of the left forehead was reported. Visual acuity impairment and diplopia were slowly progressive for 6 months associated with marked protrusion of her left forehead. Removal of left forehead lesion including the orbital ridge and total decompression of the optic canal and superior orbital fissure improved these visual symptoms dramatically. Reconstructive cranioplasty using artificial bone made by hydroxyapatite (Apaceram TM ) was very satisfactory in cosmetic appearance. Surgical indication and neuroradiological findings of cranial FD are discussed as well as a review of the literatures.
