[A case of giant frontal sinus osteoma]

Osteomas are the most frequent bone tumors of the facial bones, the most involving the frontal sinus and thus leading to symptoms of frontal sinusitis or associated complications. A twenty-one-year-old male patient presented with a growing swelling on the right side of the forehead. Examination revealed a slight facial asymmetry, a laterally shifted right orbital bulb, and disturbed vision. Cranial and orbital computed tomography showed a dense bony mass in the medial wall of the right orbit. The mass was excised totally following a bicoronal incision. The frontal and ethmoid sinuses were filled with fat tissue. Postoperatively, his vision improved to normal after two months and no complications or recurrences were detected in the sixth month.
