A noncontrast CT scan is usually sufficient, except for complicated acute sinusitis (e.g., periorbital cellulitis or abscess). Fourth, this approach would not be beneficial at a facility that is currently using very low radiation dose screening sinus CT for a majority of diagnostic examinations, with a higher radiation dose reserved for preoperative sinus CT. However, the images produced by this modality remain inadequate for nearreal-time navigation. This is especially helpful in cases of revision surgery, unusual anatomic structures or nasal polyps, all of which can make visualization of the normal sinonasal structures more difficult. The imaging data set is transferred via optical disk, CD-ROM, or computer network to the operating room, where it is loaded into the workstation. 2017 Oct 1.
