Ethmoid Osteoma With Frontal And Frontobasal Extension

Paranasal sinus osteomas are benign slow growing tumors, occasionally known to cause complications for a long time. Frontobasal extension of paranasal sinus osteoma is an uncommon localization. We present a 20 year-old-man admitted to our clinic with a complaint of pus drainage and wound from forehead for 2 weeks. The radiological images of the patient revealed a mass mimicking osteoma and extending into the frontal sinus and frontobasal area with a chronic infection. The patient was initiated antibiotics for 2 weeks and the mass was extirped through the destructed anterior wall of frontal sinus. The histopathological diagnosis was osteoma and the patient was discharged uneventfully at the 7^th day after the operation.
