Anatomic relationships of the structures exposed in type B and C infratemporal fossa approaches were studied in 20 temporal bones. The intrapetrous carotid artery (ICA), cochlea (CH), eustachian tube (ET), foramen spinosum (FS), foramen ovale (FO) and anterior foramen lacerum (AFL) were exposed by drilling of the glenoid fossa and base of middle cranial fossa. The relationships of the ICA with the cochleariform process (CP), CH, ET, FS, FO and AFL were noted along with associated measurements. The CP was lodged at a mean distance of 9.2 mm from the ICA genu. The ET was found to intersect the ICA. The mean distance of the ICA to the CH was 1.6 mm. The carotid canal was dehiscent on its horizontal portion in 30% of the bones studied and on its vertical portion in 5%. The periarterial venous plexus was found in 70% of the bones. No obvious branch was observed emerging from the vertical portion of the ICA. The FS was found to be a canal having a mean length of 5.8 mm.
在20块颞骨中研究了B型和C型颞下窝入路所暴露结构的解剖关系。通过磨除关节盂窝和中颅窝底部暴露岩内颈动脉（ICA）、耳蜗（CH）、咽鼓管（ET）、棘孔（FS）、卵圆孔（FO）和前破裂孔（AFL）。记录了ICA与匙突（CP）、CH、ET、FS、FO和AFL的关系以及相关测量值。CP位于距ICA膝部平均9.2mm处。发现ET与ICA相交。ICA到CH的平均距离为1.6mm。在所研究的骨骼中，30%的骨骼颈动脉管水平段骨质缺损，5%的骨骼垂直段骨质缺损。70%的骨骼中发现动脉周围静脉丛。未观察到从ICA垂直段发出明显分支。发现FS是一条平均长度为5.8mm的管道。
