Anatomical remarks on the fetal cavernous sinus and on the veins of the middle cranial fossa
Increasing surgical experience within the cavernous sinus region has generated increased interest in the region’s anatomy. Despite many attempts to understand the morphological complexity of the cavernous sinus, its description and interpretation are still controversial. Two main views oppose each other: classic textbooks of anatomy, but also recent studies (e.g. Harris and Rhoton , Bedford ), interpret the cavernous sinus as an intradural venous canal, which is more or less trabeculated by fibrous strands. Several other workers of the present century, however, interpret the cavernous sinus as a network of extradural veins (e.g. Taptas [21, 22], Bonnet , Parkinson [15,16, 17], a view which is not yet generally accepted. Other controversial problems of the area concern the relationship of the venous pathways with the structures that pass through the cavernous sinus area, like the internal carotid artery and the cranial nerves that run to the orbital cavity.
