Target oriented computed tomography-scanning of the paranasal sinuses.

A limited computed tomography (CT) scanning protocol for the paranasal sinuses is proposed consisting of only seven cuts in the coronal plane. A retrospective observational study has shown the ability of these cuts to demonstrate the regions of interest to the FESS surgeon. The regions are detected at a rate ranging from 85% to 96% in this sample of 100 patients. The novelty of the protocol is the principle of targeting those regions. We believe that the targeted protocol is practically feasible and provides the necessary information concerning benign sinus disease, along with the expected reduction of exposure to radiation and reduction of cost.
