Abstract
Image-guidance technology should be used in all revision endoscopic sinus surgery cases. Since first described in 1993, intraoperative computer-assisted or image-guided surgery has been advocated to improve the efficacy of endoscopic sinus surgery and reduce complications.1 Despite this, it is not clear whether the current published literature supports these claims. To date, the vast majority of publications have dealt predominantly with the accuracy of a number of commercially available image-guidance systems and accessories. It is unknown what evidence-based research exists on the efficacy of image-guided technology.
