ABSTRACT
Fibrous dysplasia is a benign pathological condition of bone in which fibrous tissue gradually expands and replaces normal bone. Histologically, it shows various degrees of osseous metaplasia. Fibrous dysplasia frequently affects the maxilla, frontal bone, and mandible. The sign and symptoms of fibrous dysplasia of head and neck vary and are related to the location and extent of bony abnormalities. Facial asymmetry is the most common sign of fibrous dysplasia, while pain and ocular proptosis are the next most frequent symptoms. Fibrous dysplasia is rare in the nasal cavity, especially involving the turbinate and nasal septum. So we report a case of fibrous dysplasia, which extensively involves the middle turbinate and nasal septum, with a review of literature.
