Sinus osteomas are benign tumors, commonly asymptomatic and discovered incidentally during radiological assessment, but they can be responsible for orbital and endocranial complications. There are 2 options for the management: clinical observation or surgery. The choice of surgical management depends on the location, size and experience of the surgeon. In most reported cases large tumors are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumors is a huge challenge for the operator. We report three cases of giant ethmoidal osteomas with orbital and intracranial extension. Literature is reviewed and etiopathogenic theories, diagnostic procedures and surgical approaches are discussed.
