Silent clinical course of giant osteomas of the frontal and ethmoidal sinuses
Osteoma most commonly affect the fronto-ethmoid sinuses. surgical removal of the frontal and ethmoidal sinus osteomas is done in symptomatic patients. They are generally asymptomatic and usually discovered by chance during radiological imaging. asymptomatic patients can be managed conservatively or submitted to surgery in spite its localization or extension. Five patients of the frontal et ethmoidal sinus giant osteoma were reported. In spite of large dimension of tumor, symptoms were generally of late onset and were a consequence of tumoral growth and compression of neighbouring organs. The computed tomography was a great contribution for diagnosis and for the choice of the surgical approach. Osteomas were radically removed in all patients with no recurrence or residual tumor. Our cases highlight the fact that patients may present with an advanced lesion but with few symptoms other than disfigurement.
