Due to the complexity and vital nature of the anatomy involved, endoscopic sinus surgery is subject to complications. In recent years, computer-based guidance systems have been developed to incorporate preoperative computed tomography during a procedure. A pointer can be placed at a tissue surface under endoscopic visualization. The location of the tip of that pointer is simultaneously displayed on sagittal, axial, and coronal CT images. This localization provides information as to the surrounding anatomy not visible from the direct view of the surface. It is hoped that such a technique could reduce the duration and improve the safety of endoscopic sinus surgery. The number of systems currently under development testify to the interest in the technology, and the literature presents evidence on behalf of the technique's usefulness and potential.
