The extension of paranasal sinus malignant neoplasms into the orbit presents one of the arguments for carrying out orbital exenteration. One method of assessing the extension is computed tomography (CT), but its reliability is still questionable. ⋯ In only four of seven patients without ophthalmic symptoms did CT scanning appear to match the factual situation. Apparently CT scanning is not always reliable in patients without ophthalmic symptoms.
