Background: Osteoma is a bony slow growing benign tumor in one of the sinuses. It is usually asymptomatic but clinical symptoms will occur by its overgrowth, occupation of sinus space and obstruction of ostia.
Methods : This descriptive, cross-sectional, retrospective study was done by accessing the medical records of 17 patients with paranasal sinuses osteomas admitted in Tehran Amir Alam Hospital during 1999-2008.
Results : The mean age of the participants was 33.9 years and 12 (70.6%) were male and 5 (29.4%) were female. No positive family histories existed for the lesions. The mean time interval between the onset of symptom and attending the hospital was 4.4 years.
Frontal followed by ethmoid sinus osteomas were more common in comparison to other sinuses. The most reported symptoms in frontal sinus osteomas were upper eyelid inflation and headache; and proptosis, nasal congestions and diplopia in ethmoid sinus osteomas. Most patients had been endoscopically treated.
Conclusion: In small-to-medium-sized osteomas with no invasion into orbit or skull base, endoscopic surgery is the treatment of choice with minimum side-effects.
