Clinical Experience in Treatment of the Giant Frontal Sinus Osteoma using Cranialization

ABSTRACT

Frontal sinus osteoma is one of the rare diseases and is diagnosed incidentally by skull X-ray. After the disease is confirmed, long term follow-up is necessary. The etiology of the disease is usually unknown and almost all of the patients has any kind of symptoms or signs. The most of the symptoms of this disease are pain, headache, swelling and lagophthalmos. Frontal sinus osteoma has characteristic features such as radiopaque, mass like lesion in the frontal sinus. Operation of the frontal sinus osteoma is not necessary unless it has symptoms or infection sign. We experienced one case and operated the osteoma and reconstructed frontal sinus by cranialization and bihalving calvarial bone graft. The result is satisfactory without complication.
