BACKGROUND: Fibro-osseous lesions of the paranasal sinuses are an uncommon heterogeneous group of lesions with variable clinical presentation. It is unclear whether these lesions directly cause symptoms or secondarily obstruct the sinuses with resultant rhinosinusitis. We have used an expectant management approach in selected @entity1 that includes observation with serial scans or @entity50 ( @entity50 ) to improve the outflow tract of the affected sinus without resection of the lesion. The purpose of this work is to review our experience with management of @entity5578 . METHODS: Retrospective chart review from 1997 to 2009. RESULTS: A total of 44 @entity1 were identified in this study. There were 19 (43%) @entity1181 and 25 (57%) @entity82 cases. The presenting symptoms were mainly sinonasal with @entity10 (36%), @entity158 /pressure (19%), and nasal obstruction (17%). Two @entity1 (4.5%) presented with proptosis and @entity892 . Five (11%) @entity1 had associated @entity480 . The diagnosis was an incidental finding in seventeen (38%) cases. Twenty-two (50%) @entity1 were managed conservatively with serial computed tomography (CT) scans to monitor for interval growth over a mean interval of 41.8 months (range, 13-130 months). There were 2 @entity1 in the observation group with CT scan evidence of interval growth with an increase in size of 1 mm and 9 mm over 130 and 36 months, respectively. Twelve symptomatic @entity1 (27%) underwent @entity50 without resection of the lesion, with symptomatic improvement in 11 @entity1 (92%). Four @entity1 (9%) underwent endoscopic biopsy to attain histological diagnosis. Six (13%) @entity1 in this study had resection of their lesion with 5 of the @entity1 having symptomatic improvement following resection. CONCLUSION: In @entity1 with fibro-osseous lesions, we support an expectant management approach of asymptomatic @entity1 with observation and serial imaging, treating selected symptomatic @entity1 with @entity50 and resection of the lesion in @entity1 with orbital complications, progressive growth of the lesion, or persistent symptoms.
