Large Frontoorbital Osteoma Causing Ptosis.
Osteomas are the most frequent benign tumor of the paranasal sinuses. The commonest site is the frontal sinus but intraorbital extension of frontal osteoma is rare. Here, the authors report a 15-year-old adolescent boy who presented with left superior orbital rim swelling and ptosis. Waters radiography and computed tomographic scan revealed a bone density mass in the left frontal sinus with upper orbital wall extension. The tumor was removed via open eyebrow incision. The histopathologic evaluation was consistent with osteoma.
