Gross anatomic sections of isolated temporal bones (TB) were compared with high resolution computed tomography (CT) scans obtained utilizing contiguous 1.5-mm thick slices in the transaxial, coronal, and sagittal planes. Each TB was then sectioned at 2.0-mm intervals in planes parallel to those of the CT scans. Both the cochlear and vestibular aqueducts were best visualized in the coronal plane; the transaxial plane proved less reliable and the sagittal plane was not useful at all. The cochlear aqueduct in the coronal plane appears as a funnel-shaped configuration with its widest portion opening into the subarachnoid space. The vestibular aqueduct at its opening into the epidural space is well visualized in the coronal plane, and as it traverses the bone toward the vestibule it appears as an oval to spherical lucency, whereas in transaxial sections it is seen as a small longitudinal lucency.
将分离的颞骨（TB）的大体解剖切片与利用在横轴位、冠状位和矢状位平面上连续的1.5毫米厚切片获得的高分辨率计算机断层扫描（CT）图像进行比较。然后，将每个颞骨在与CT扫描平面平行的平面上以2.0毫米的间隔进行切片。耳蜗导水管和前庭导水管在冠状面中显示最佳；横轴位平面的可靠性较差，矢状面则完全无用。冠状面中的耳蜗导水管呈漏斗状结构，其最宽部分通向蛛网膜下腔。前庭导水管在硬膜外间隙的开口在冠状面中清晰可见，当其穿过骨质朝向前庭时，呈椭圆形至球形的透亮区，而在横轴位切片中则表现为小的纵向透亮区。
