摘　　要：目的:探讨额窦引流系统的CT解剖特征。方法:采用螺旋CT,对15例正常成人头颅骨骼标本行横断位扫描,并在工作站行冠状面和矢状面重建。结果:螺旋CT三维成像技术能清楚显示钩突的附着部位和类型,其中在30侧钩突中,纸样板12侧,鼻丘气房3侧,中鼻甲7侧,前颅底5侧,分叉3侧;在额隐窝气房26侧中,终末气房15侧,鼻丘气房5侧,前筛气房6侧;额窦内气房28侧,有额气房8侧,眶上气房12侧,额窦中隔气房即M气房8侧。结论:了解额窦引流系统的CT解剖特征,可以为慢性额窦炎术前提供有用的信息。Objective：To study the CT anatomic features of frontal drainage system. Methods： 15 cases of normal adults head specimens underwent axial spiral CT scanming with coronal and sagittal 3-dimensional reconstruction.Results： 3-dimensional reconstruction spiral CT could clearly demonstrate the location and type of uneinate process. Of 30 sides of uneinate process, it adhered to the lamina papyracea in 12 sides（40%）, agger nasi wall in 3 sides（10%）, middle turbinate in 7 sides（23.3%）, floor of anterior cranial fossa in 5 sides （16.7%）, and uneinate process furcation in 3 sides（10%）. Of 26 sides of frontal recess cells, terminal ceils accounted for 15 sides（57.7%）, agger nasi cells in 5 eases（19.2%）, anterior ethmoidal cells in 6 sides（23.1%）, Of the 28 eases of intrafrontal cells, frontal ceils accounted for 8 sides （28.6%）, superobital cells in 12 eases （42.9%）, septum of frontal sinus cells （M cells） in 8 eases （28.8%）. Conclusion： The demonstration of the anatomic features of frontal sinus on spiral CT can provide useful information for chronic frontal sinusitis.
