Pediculated Fibrous Dysplasia in Maxillary Sinus: A Case Report

Fibrous dysplasia is a bone disorder characterized by progressive replacement of normal bone by fibrous bone tissue. Common involving sites of fibrous dysplasia are the skeletal system including long bones, ribs, craniofacial bones and the pelvis. If maxilla were affected by fibrous dysplasia, antrum is almost always involved. And fibrous dyplasia in maxillary sinus were followed the shape of bone. In our case, the lesion involves antrum but, its shape was different from typical fibrous dysplasia pattern of maxillary sinus. Therefore we report a case of monostotic pediculated fibrous dysplasia in the maxillary sinus with a review of literature.
