摘　　要：目的通过冠状位CT扫描图像来观察筛骨钩突上端的附着及额窦引流与钩突间的关系。方法选择我科因鼻窦炎等鼻部疾病住院患者50例,行64层CT扫描,去除局部结构不清者5侧,观察95侧患者筛骨钩突上端附着、额窦引流情况及规律。结果62%的筛骨钩突上端有多个(两个或以上)附着点;94%(89/95)额窦直接引流入中鼻道;当筛骨钩突上端有多个附着点时,95%(56/59)的额窦直接引流入中鼻道。结论鼻窦冠状位可清晰显示额隐窝周围结构,能基本满足临床手术要求;筛骨钩突上端附着方式与额窦引流关系密切,清楚认识其规律性对于鼻内窥镜下额窦手术有重要指导意义。Objective To recognize the regularity of the uncinate process superior attachment sites and frontal sinus drainage pathway in rhino-patients. Methods 50 coronal computed tomography scans of the sinuses performed from July 2007 to November 2007 were evaluated. Result About 62% （59/95） of the uncinate process had two or more superior attachment sites,and the other 38%（36/95） had one superior attachment site.When the uncinate process had two or more superior attachment sites, 95 % （56/59） of frontal sinuses directly drained into the middle nasal meatus. Conclusion The structure of the frontal recess could be clearly recognized by coronal computed tomography.
