ABSTRACT

Image-guided surgery (IGS) is a new technology that has become an important adjunctive tool in sinus and skull-base surgery. Image-guidance systems rely on preoperative CT and MRI data images to provide the surgeon with a real-time 3D visual localization of the surgical instruments relative to the patient’s anatomy during surgery. Therefore, movements of the surgical instruments are tracked by the system and projected onto the preoperative dataset displayed on the monitor, providing a precise surgical roadmap. The technology continues to progress at a fast pace with many systems currently available, each with its own benefits and drawbacks.
