目的 :评价窦口鼻道复合体HRCT检查及临床应用价值。材料与方法 :分析 10 6例冠状位及横断位HRCT扫描图像。采用层厚 3mm ,层间距 5mm扫描。其中 12例采用层厚 3mm ,层间距 3mm。结果 :慢性鼻窦炎患者占 92 % ,鼻中隔偏曲 83 % ,中鼻甲气化 48% ,中鼻甲反向弯曲 2 0 % ,Haller气房 41% ,筛泡过度气化 46 % ,钩突偏曲 19% ,扫描层间距为5mm ,窦口鼻道复合体显示率为 49%。层间距 3mm为 10 0 %。结论 :窦口鼻道复合体变异与慢性鼻窦炎的发生有明确的相关性 ,鼻窦HRCT冠状位扫描是显示该区域最佳影像学技术 ,对功能性鼻内窥镜手术具有指导价值
OBJECTIVE: To evaluate the HRCT examination and clinical value of ostiomeatal complex. Materials and Methods: 106 coronal and transverse HRCT images were analyzed. Layer thickness 3mm, 5mm spacing layer scan. Among them, 12 cases used layer thickness 3mm and layer spacing 3mm. Results: 92% of patients with chronic sinusitis, 83% of nasal septum deviation, 48% of middle turbinate gas, 20% of middle turbinate reverse curve, 41% of Haller’s air chamber, 46% of vesicle over-gasification, 19%, scanning layer spacing of 5mm, sinus ostiomerization complex showed a rate of 49%. Layer spacing 3mm to 10 0%. CONCLUSIONS: The variation of sinus ostiometrics complex has a clear correlation with the occurrence of chronic rhinosinusitis. Coronal sinus CT scan of coronal sinus is the best imaging technique in this area, which is of guiding value for functional endoscopic sinus surgery
