Abstract
- Fibrous dysplasia is a developmental disease of bone in which there is replacement of normal spongiosa and filling of the medullary cavity of affected bones by an abnormal fibrous tissue that contains trabeculae of poorly calcified primitive bone formed by osseous metaplasia. Fibrous dysplasia arising in the paranasal sinus is rare and often presents a diagnostic challenge. It is usually secondary to extension of disease from adjacent bones and is rarely limited to the sinuses. We have described two cases of fibrous dysplasia involving the sphenoid sinus and a case of fibrous dysplasia involving the sphenoethmoid sinus with narrowed orbital apex. A brief update of the clinical aspects, radiolographic appearance, diagnosis, and management of craniofacial fibrous dysplasia is proved.
