We present a case of ethmoid sinus osteoma. A 66-year-old woman was referred with an asymptomatic mass of the nose. Radiographs showed a rounded homogeneous radiodense lesion in the right ethmoid sinus, suggesting an osseous lesion. Computed tomography demonstrated a multi-lobulated high density lesion (2.0×1.5 cm in size) occupying the ethmoid sinus. The lesion was attached to the nasal septum and extended to the posterior orbit. Total excision of the mass lesion was performed under general anesthesia via the oral vestibular approach with an operating microscope. Histopathological examination revealed eburneous-type osteoma. The postoperative course was uneventful.
