Computed tomography scans serve as a critical 'roadmap' for functional endoscopic sinus surgery. A systematic evaluation of such scans, and an awareness of any anatomical variants that may modify one's surgical approach, allow one to pre-empt complications. This article describes, from a novice's perspective, two methods of evaluating paranasal sinus computed tomography scans: a quick assessment technique; and a step-wise, operative approach covering radiological features relevant to pre- and peri-operative management.
计算机断层扫描是功能性鼻内镜鼻窦手术的关键“路线图”。对这类扫描进行系统评估，并了解可能改变手术方式的任何解剖变异，有助于预防并发症。本文从新手的角度介绍了两种评估鼻窦计算机断层扫描的方法：快速评估技术；以及一种逐步的手术方法，涵盖与术前和围手术期管理相关的放射学特征。
