Lesions affecting the cavernous sinus may affect isolated nerves or all the nerves traversing through it. The pituitary gland lies between the two paired cavernous sinuses. An abnormally growing pituitary adenoma, sitting on the bony sella turcica, will expand in the direction of least resistance and eventually invade the cavernous sinus. [4]
Medially to the trigeminal ganglion are the internal carotid artery, and the posterior part of the cavernous sinus. [2] The motor root of the trigeminal nerve passes beneath the trigeminal ganglion to exit the skull through the foramen ovale. [2] The greater petrosal nerve passes underneath the trigeminal ganglion to reach the foramen lacerum.
The ophthalmic nerve (CN V 1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V) , a cranial nerve . It has three major branches which provide sensory innervation to the eye , and the skin of the upper face and anterior scalp , as well as other structures of the head.
lateral wall of the cavernous sinus superomedially; clivus medially; posterior petrous face inferolaterally; Within the dural confines of the trigeminal cave, there is a continuation of subarachnoid space along the posterior aspect of the cave, representing a continuation of the cerebral basal cisterns.

The Cavernous Sinus. Each trochlear nerve originates from a trochlear nucleus in the medial midbrain.From their respective nuclei, the two trochlear nerves then travel dorsal-ward through the substance of the midbrain surrounded by the periaqueductal gray, crossing over (decussating) within the midbrain before emerging from the dorsal midbrain [3] [4] just inferior to the inferior colliculus. [4]
The cavernous nerve plexus (also called the Walther plexus [1]) is situated below and medial to that part of the internal carotid artery which is placed by the side of the sella turcica in the cavernous sinus, and is formed chiefly by the medial division of the internal carotid nerve.
Generally, people describe a sinus headache as a feeling of facial pain or pressure in the sinus area that might radiate to the rest of the head. "People typically talk about it like a pressure ...
It transmits to the orbital cavity the oculomotor, the trochlear, the ophthalmic division of the trigeminal, and the abducent nerves, some filaments from the cavernous plexus of the sympathetic, and the orbital branch of the middle meningeal artery; and from the orbital cavity a recurrent branch from the lacrimal artery to the dura mater, and ...
