Abstract
Computerized tomography (CT) imaging provides detailed information on the paranasal sinuses that is not available from standard radiographs. The planning and safety of endoscopic sinus surgery is greatly improved by CT imaging. Frequently standard radiographs are ordered because of the reduced cost. The four-slice CT Mini-series outlined in this paper provides high resolution bone and soft tissue imaging of the key surgical areas. The Mini-series comprises three precisely placed coronal slices and one axial slice. An average Mini-series takes 20 min to perform at a cost of $NZ66.00. Standard radiographs take up to 30 min to perform at a cost of $NZ38.00.
