Computed tomography (ct) scanning is the examination of choice in sinusitis, particularly in cases of chronic sinus disease, providing excellent detail of sinus anatomy. the ostiomeatal units are brilliantly shown on ct scans, which provide greater definition of the pathology than do other images, especially within the sphenoid and ethmoid sinuses.
