Image Guided Endoscopic Sinus Surgery: First Experience from Kashmir Valley.

Image guidance is best suited to paranasal sinus surgeries as these demand a high degree of anatomical precision because of close proximity to orbit and cranial cavity which at times is challenging in patients with frequent anatomical variations. This study is aimed to describe our first experience of using image guided endoscopic sinus surgery in Kashmir valley in terms of real time correlation between the operative field and the preoperative imaging; to evaluate its utility in disease clearance and to evaluate patient reported outcome measures using (pre and post-op) VAS, SNOT-22, Lund Mackey endoscopic and radiological scores. This prospective observational study was conducted from September 2016 to August 2018.
