【摘要】目的：为了提供对内窥镜鼻窦外科及颅底外科手术更具指导意义的后筛窦影像解剖资料。方法：取50具成人头颅标本，行冠状位、矢状位及水平位薄层CT扫，从不同层面及不同方位观测后筛的气化发育情况。结果：发现属管前型的占23%(23侧)；半管型的占28%(28侧)；全管型的占33%(33侧)；蝶鞍型的占16%(16侧)。其中两侧气化分型完全相同者占33例(66侧)；两侧气化不相同者占17例(34侧)。发现属Ⅰ°后筛窦的占43%(43侧)；属Ⅱ°后筛窦的占35%(35侧)，其中属Ⅱa°后筛窦的占19%(19侧)，属Ⅱb°后筛窦的占16%(16侧)；属Ⅲ°后筛窦的占22%(22侧)。其中两侧分度完全相同者占29例(58侧)；两侧分度不相同者占21例(42侧)。结论：后筛窦影像解剖分型分度对内窥镜鼻窦外科及颅底外科手术具有实际的指导意义。

Objective :To provide imaging anatomy basis of the psoterior ethmoid sinus for endoscopic sinus surgery and basicranial surgery.Methods:Coronal,sagittal and axial slice CT scanning was performed on 50 adult head specimens to observe the pneumatization and development of the posterior ethmoid sinus on different slices and drections.Results:According to its appearance,the posterior ethmoid sinus could be divided into four types such as pre-canal type which accounted for,half-canal type was 23% (23 sides),28%,33% and 16% respectively.In 33 cases,the pneumatizzation and classification of both sides were identical,while the other 17 cases were non-identical.Moreover,the pneumatization of 43% posterior ethmoid sinus was to degree Ⅰ ......
