Giant Post-Traumatic Frontoethmoid Osteoma: Diagnostic, Therapeutic and Reconstructive Approach.

Paranasal sinus osteomas are rare, slow-growing and benign lesions with potentially serious complications. They usually remain asymptomatic but when osteomas grow they can lead to local complications and cause evident aesthetic deformity due to the direct mass effect and in these situations, surgery is required. This is a report of a 30-year-old man with a rare giant post-traumatic osteoma that occupies the right nasal fossa, ethmoidal cells and frontal sinuses with extension into the right orbit.
