Image-guided surgery of the paranasal sinuses and skull base.

The application of image-guidance technology to sinonasal and skull base procedures has ushered in a new era of surgical approaches to conditions affecting this region. The ability of image-guidance systems to provide the surgeon with enhanced anatomic localization during endoscopic procedures offers the potential for fewer intraoperative complications and improved clinical outcomes. In a remarkably short time, navigation systems have gone from being a curious novelty to a near-necessity in some complex skull base procedures.
