상악동에 발생한 골종 1례

The osteoma is a slowly growing benign tumor of bone, which occasionally produces symptoms of a space-occupying lesion. Osteomas are most common in the frontal sinus, followed by the ethmoid, maxillary antrum, and sphenoid sinus, in decreasing order of frequency.

The etiology of the tumor is controversial and as yet unresolved, but there are three classical theories: embryological, traumatic and infective. Pathologically, osteomas are usually classified as spongy, compact, ivory or mixed.

The authors have experienced a case, which report this case with brief review of literature.
