Cranial nerve foramina are integral exits from the confines of the skull. Despite their significance in cranial nerve pathologies, there has been no comprehensive anatomical review of these structures. Owing to the extensive nature of this topic we have divided our review into two parts; Part II, presented here, focuses on the foramina of the posterior cranial fossa and discusses each foramen's shape, orientation, size, surrounding structures, and structures that pass through it. Furthermore, by comparing foramen sizes against the cross-sectional areas of their contents, we determine the amount of free space available within each. We also review lesions that can obstruct each foramen and discuss the clinical consequences.
颅神经孔是颅骨范围内不可或缺的出口。尽管它们在颅神经病变中具有重要意义，但尚未对这些结构进行全面的解剖学综述。由于该主题范围广泛，我们将综述分为两部分；此处呈现的第二部分聚焦于后颅窝的孔，并讨论每个孔的形状、方向、大小、周围结构以及穿过它的结构。此外，通过将孔的大小与其内容物的横截面积进行比较，我们确定每个孔内可用的自由空间量。我们还综述了可能阻塞每个孔的病变并讨论其临床后果。
