Monostotic fibrous dysplasia of temporal bone: Report of two cases and review of its characteristics

Abstract

Fibrous dysplasia is a bone disorder of unknown origin characterized by slow, progressive replacement of bone by abnormal proliferative isomorphic fibrous tissue. The disease was first described by McCune and Bruch in 1937. Craniofacial involvement is found in only 10% of cases of the monostotic variety, while temporal bone involvement is rare. We report herein two cases of monostotic fibrous dysplasia involving temporal bone and briefly review the clinical implications and management of the disease.
