Preoperative Computed-Tomography for Endoscopic Sinus Surgery: A Simplified Checklist

Abstract

Introduction: Endoscopic sinus surgery (ESS) gained growing popularity with indications expanding beyond rhinosinusitis. Preoperative high-resolution computed tomography (CT) scan is essential in providing the surgical map for surgeons. In addition of being a diagnostic imaging technique, it gives valuable information about origin, nature and extension of the pathology to adjacent structures. Therefore, preoperative review of para-nasal sinuses (PNS) CT scan is crucial in order to perform successful and complete surgery with avoidance of complications. Variable preoperative CT checklists were published in literature in order to standardize radiological reporting and assess surgical planning. However, those lists have rarely been utilized which is very likely due to complexity, deficiencies and low clinical applicability. The main objective of this research is to propose a new comprehensive, simplified, practical, and applicable pre-endoscopic sinus surgery CT scan checklist.
