目的 探讨冠状位高分辨CT对副鼻窦疾病的诊断价值,提高诊断水平.方法 回顾性分析经手术和病理证实的100例患者的副鼻窦CT表现,所有患者均为仰卧、冠状位扫描,层厚、层间距分别为3、6 mm,高分辨骨算法重建.根据CT表现不同分为三个组,即解剖变异组、炎症组和肿瘤组.结果 解剖变异组55例118个部位,所有图像都能清晰显示解剖变异和鼻道窦口复合体等重要结构;炎症组70例,肿瘤组10例均被手术、病理证实.结论 HRCT对副鼻窦病变可以准确诊断,对窦壁和窦外的病变可以完整描述作出,HRCT应作为FESS术前常规检查,对设计手术方式、判断手术疗效和有无复发都具有临床意义.

Objective The value of coronal high-resolution CT was assessed in the evaluation of paranasal sinus diseases. Methods A retrospective study of paranasal sinus CT imaging of 100 patients,which were confirmed by surgery and pathology. Bachlying、 coronal scanning, 3 mm slice thickness, 6 mm slice pitch and high-resolution bone algorithm reconstruction for all the patients. We got there groups according to the CT manifest: anatomy variation、inflammation and tumor Results There were 55 patients and 118 sites in anatomy variation group, all the images can display the important structure of anatomy variation and ostiomeatal complex clearly ;70 patients in inflammation group and 10 patients in tumor group,which were all confirmed by surgery and pathology. Conclusion HRCT could accurately diagnose paranasal sinus diseases,and completely describe the lesion of either the sinus wall and out of the sinus. HRCT should be the routine examination before FESS, it has great clinical value for designing surgical plan and evaluating the effect and recurrence.
