Cavernous sinus thrombosis

Cavernous sinus thrombosis. Owing to the great number of structures passing through or in the lateral wall of the cavernous sinus, a blockage or infection in this region has serious consequences which may include damage to the third, fourth, fifth and sixth cranial nerves. Infections around the face and forehead may travel into the cavernous sinus, via the ophthalmic veins.
