The infratemporal fossa is one of the most difficult regions of skull base to access surgically. The presence of the ossified pterygospinous and pterygoalar ligaments makes it more critical and difficult to access, with an occasional entrapment of structures like the mandibular nerve (MN) and its branches. During a routine dissection of an adult male cadaver, an unusual course of the lingual nerve (LN) was found with an entrapment of the nerve between the ossified pterygospinous ligament and the medial pterygoid muscle. Furthermore, all the three branches of the posterior division of the mandibular nerve communicated with each other by two anastomosing branches. The clinical significance of the present variations has been discussed (Fig. 1, Ref. 23).
颞下窝是颅底手术中最难进入的区域之一。翼棘韧带和翼突韧带的骨化使得进入该区域更为关键和困难，偶尔会出现下颌神经（MN）及其分支等结构的卡压。在对一具成年男性尸体进行常规解剖时，发现舌神经（LN）走行异常，该神经被骨化的翼棘韧带和翼内肌之间卡压。此外，下颌神经后支的所有三个分支通过两个吻合支相互连通。已讨论了目前这些变异的临床意义（图1，参考文献23）。
