Structures passing through sinus
Internal carotid artery and abducens nerve are inside the sinus lumen.
Lateral wall structures
CN III, CN IV, V1, and V2 lie in the lateral wall.
Medial relation to pituitary
Pituitary is medial; cavernous sinus is lateral to it.
Venous connections
Facial veins connect via ophthalmic veins to the cavernous sinus.
Venous drainage pathways
Cavernous sinus drains into superior and inferior petrosal sinuses.
CN VI location
Within the venous blood space of the sinus lumen.
Nerves in lateral wall
CN III, IV, V1, V2 are in the lateral wall, outside the lumen.
Pituitary position
Medially within the sella turcica, lateral to the cavernous sinus.
Facial infection route
Facial veins connect to cavernous sinus via ophthalmic veins.
Drainage along petrous bone
Superior and inferior petrosal sinuses drain the cavernous sinus.
