Management of a large frontoethmoid osteoma with sinus cranialization and cranial bone graft reconstruction

Abstract Osteoma represents the most common benign neoplasm of the nose and paranasal sinuses. The etiology of osteomas is uncertain, and the majority occur in the frontal, ethmoid, and maxillary sinuses in that order. We present a 14-year-old male with a large frontoethmoid osteoma that required frontal sinus cranialization and pericranial bone graft reconstruction following removal. The osteoma recurred 6 months postoperatively and was excised. Treatment alternatives and a review of the literature are presented.
