Image Guided surgery is one of the most popular and effective surgeries performed to heal sinusitis. One of the major reasons to opt for this surgery is the physical closeness of the sinuses to the brain, the eye, and major arteries. These are the areas of concern when a fiber optic tube is inserted into the sinus region. With the help of this new image guided endoscopic surgery, this concern is alleviated to much extent. The image guided surgery can be recommended for severe forms of chronic sinusitis. The image-guided surgery is also very useful in cases when previous sinus surgery has distorted anatomical landmark, or where a patient’s sinus anatomy is abnormal, making conventional surgery difficult. The Image-guided surgery (IGS) is a concurrent correlation of the operative field to a preoperative imaging data set that shows the precise location of a selected surgical instrument to the surrounding structures. The Image guided surgery was developed for neurosurgery and is gradually adopted as endoscopic sinus surgery.
In the Image guidance a near-three-dimensional mapping system is used that combines computed tomography (CT) scans and real-time information about the exact position of surgical instruments using infrared signals. By adopting this method, surgeons can steer their surgical instruments through intricate sinus passages and provide surgical relief more precisely and easily. One interesting factor is that the Image guidance uses some of the similar stealth principles used by the United States armed forces to guide bombs to their target.
