摘　　要：目的 :为临床开展鞍区手术提供一组最后筛房的影像解剖学资料。方法 :取 5 0具成人头颅标本 ,行鼻窦冠状位及水平位薄层CT扫描 ,重点观测后筛窦最后筛房的影像解剖形态及其毗邻关系。结果 :测得其矢状径位于 5 .8～ 2 1.5mm之间 ;垂直径位于 9.4～ 2 6 .0mm之间 ;左右径位于 5 .9～ 2 3 .6mm之间。其中 ,最后筛房大于或等于同侧蝶窦腔的有 2 3 % ( 2 3侧 )。结论 :最后筛房与蝶窦、视神经管之间的解剖关系可形成蝶上筛房、蝶旁筛房或Onodi窦。Provide image anatomy basis of the ultimate ethmoid sinus for the surgical approach via saddle area.Methods:The ethmoid sinuses of 50 adult heads were coronal and thinner axial CT scanned.The ultimate ethmoid sinus was observed and measured on these CT images.Results:The sagittal diameter of ultimate ethmoid was 5.8～21.5 mm,the vertical diameter was 9.4～26.0 mm and the transverse diameter was 5.9～23.6 mm.In 23% specimens,the ultimate ethmoid cell was larger than or equal to the ipsilateral sphenoid sinus.According to the relative location to sphenoid sinus,the ultimate ethmoid sinus cell will form the super sphenoid ethmoid cell,side sphenlidethmoid cell or Onodi sinus.Conclusions:The coronal and axial CT scanning of the nasal sinuses should bendfit the its clinical operation and image anatomy study.
