Primary osteoma of the orbit with atypical facial pain: case report and literature review

Osteoma is a benign, slowly growing tumor that mainly occurs in the bones and cavities of the middle third of the face, representing the most frequent benign tumor of the paranasal sinuses. It rarely originates primarily from the orbit. Most of these lesions develop in the fourth to fifth decades of life, and are more commonly encountered in males. In the English literature, there are so far three reported cases of primary osteoma of the orbit that originated from the sphenoid bone. Here we present another case of a primary osteoma of the orbit presenting with atypical facial pain and discuss the relevant literature.
