Background & Objectives: Fibrous dysplasia of the paranasal sinus is rare. It is usually secondary to the extension of disease from adjacent bones and rarely limited to the sinuses. The purpose of this study is to get an improved appreciation of the clinical features and courses of fibrous dysplasia involving paranasal sinuses.
Subjects & Methods: Medical records of 15 patients diagnosed as fibrous dysplasia involving paranasal sinuses from 1990 to 2004 were reviewed retrospectively. Clinical informations including age of diagnosis, presenting symptoms, radiographic findings, treatment and clinical outcome for each patient were analyzed. The male to female ratio was 7 : 8. Their ages ranged from 7 to 68 with the median of 32. Seven patients were younger than 30 years old at presentation.
Results: The most common complaint was headache followed by facial swelling. The mean duration of illness was 11 months. In the findings of CT, eight patients belonged to the sclerotic type, six to the pagetoid type, and one the tocystic type. Eight patients were polyostotic while the others were monostotic. The most commonly involved sinus was the sphenoid sinus followed by ethmoid sinus. Seven patients who had facial swelling, exophthalmos or nasal obstruction underwent surgery, and in four of them, the lesion was in progression or recurred. Lesions in eight patients who were older than 30 years old and had no symptoms except headache did not progress thereafter.
Conclusion: The progression of fibrous dysplasia stops when the bony growth is completed. Thus, if the patients are diagnosed with fibrous dysplasia over the age of 30 and do not have specific symptoms, there may be no need for surgical treatment.
