为探讨鼻窦CT冠位扫描对具窦内窥镜手术的指导意义，将260例（466侧）鼻窦疾病患者的CT冠位扫描所见与内窥镜鼻窦手术结果进行对比分析。结果显示鼻窦CT冠位扫描与临床诊断符合率为99．2％。认为，通过影像学检查指导鼻内窥镜手术，有助于术中识别鼻腔鼻窦的各种解剖变异，这对于手术的难易估计及并发症的预防均起着积极作用，并同时指出CT冠位扫描尚存在一定局限性。
In order to explore the guiding significance of sinus CT scanning in sinus surgery, 260 cases (466 sides) of sinus diseases were compared with those of endoscopic sinus surgery. The results showed that the coincidence rate of coronal sinus CT scan and clinical diagnosis was 99.2%. That the guidance of nasal endoscopic surgery through imaging examination is conducive to intraoperative identification of various anatomical variations of the nasal sinuses, which plays a positive role in the difficult to estimate the operation and prevention of complications, and also pointed out CT Bit scan there are still some limitations.
