The carotid canal conveys a large artery and lies in close topographic relationship to the basal turn of the cochlea. The bony wall between them consists in some cases only of the petrous bone of the otic capsule. It can be as thin as 0.2 mm. In other cases the distance can be more than 6 mm. A systematic assessment of the relationship between these two structures was performed on plastic casts of 173 human temporal bone specimens in order to investigate the range of normal variation. The topography in this region can be visualized by multidirectional tomography or CT.
颈动脉管容纳一条大动脉，且与耳蜗底转在解剖位置上关系密切。它们之间的骨壁在某些情况下仅由耳囊的岩骨组成，其厚度可薄至0.2毫米。在其他情况下，两者距离可能超过6毫米。为了研究正常变异范围，对173例人类颞骨标本的塑料铸型进行了这两个结构之间关系的系统评估。该区域的解剖结构可通过多方向断层扫描或CT显示。
