Imaging for endoscopic sinus surgery in adults

Computerized tomography (CT) offers the gold standard in terms of imaging t he extent of disease and the fine detailed anatomy, both pre-requisites to the safe practice of endoscopic sinus surgery. Neither plain X-rays nor mag netic resonance imaging (MRI) offer optimal information in this respect. A variety of protocols minimizing radiation dose to the lens whilst providing high quality images are presented together with a menu of anatomical featu res that require careful evaluation pre-operatively.
