Details of Image-Guided Endoscopic Nasal and Sinus Surgery

Image guide-guided surgery (IGS) is extremely useful for anatomic location in at-risk sinus surgery: extensive inflammatory disease, sinus cavity revision, and frontal sinus, posterior ethmoid, sphenoid or nasosinal tumor surgery. There are two different on the market, based on electromagnetic and infrared detection, respectively; optimal functioning depends on calibration. IGS is only a location aid, complementary to and not a substiture for endoscopy. It enables the experienced endonasal surgeon to check the endoscopic location at any time, and provided appreciable “psychological” comfort in what are difficult and sometimes stressful operations.
