Navigational systems for sinus surgery: new developments.

Abstract

The last 15 years have seen an explosion in the understanding and treatment of paranasal sinus disease. On the heels of the development of computed tomography (CT), a new modality of paranasal intervention was propagated with the introduction of rigid telescopic technology. In the last 10 years, both computer hardware and software improvements have permitted the otolaryngologist to further this endoscopic ability with CT-guided navigational systems. This article reviews the technology, utility, and advances in the field of image-guided endoscopic sinus surgery.
