Fibrous dysplasia with cystic appearance in maxillary sinus

Fibrous dysplasia (FD) in the paranasal sinuses is uncommon, and its manage ment may be difficult. We report the case of a 25-year-old female with FD e xhibiting a cystic appearance in the maxillary sinus. The patient had been complaining of facial swelling for few years. Imagery study showed a cystic lesion and dense bone changes in the maxillary bone. Inferior meatal antro stomy with a nasal endoscope failed to confirm a histological diagnosis. Af ter a 3-year follow-up, the degree of facial swelling was unchanged, and th e patient underwent middle meatal antrostomy and was diagnosed with FD. (C) 2001 Elsevier Science Ireland Ltd.
