The maxillary branch passes external to, but immediately adjacent to, the lateral wall of the sinus. [1] The optic nerve lies just above and outside the cavernous sinus, superior and lateral to the pituitary gland on each side, and enters the orbital apex via the optic canal.
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 petrolingual ligament lies at the posteroinferior aspect of the lateral wall of the cavernous sinus and marks the point at which the internal carotid artery enters the cavernous sinus. Anatomically, the petrolingual ligament demarcates two of the segments of the internal carotid artery:
the lateral pterygoid plate, part of the lateral pterygoid muscle and lateral pharyngeal wall medially; ... to the cavernous sinus via the pterygoid plexus of veins.
The anterior clinoid process is a pyramid-shaped bony projection of the lesser wing of the sphenoid bone and forms part of the lateral wall of the optic canal. Between each ACP lies the sella turcica, which holds the pituitary gland. Additionally, the ACP is part of the anterior roof of the cavernous sinus. The posterior and inferior portions ...
Oblique section through the cavernous sinus. The cavernous segment, or C4, of the internal carotid artery begins at the petrolingual ligament and extends to the proximal dural ring, which is formed by the medial and inferior periosteum of the anterior clinoid process. The cavernous segment is surrounded by the cavernous sinus.
It passes anterior-ward along the lateral wall of the cavernous sinus inferior to the oculomotor nerve (CN III) and trochlear nerve (N IV). [1] It exits the skull into the orbit through the superior orbital fissure. [2]
In neuroanatomy, the maxillary nerve (V 2) is one of the three branches or divisions of the trigeminal nerve, the fifth (CN V) cranial nerve.It comprises the principal functions of sensation from the maxilla, nasal cavity, sinuses, the palate and subsequently that of the mid-face, [1] and is intermediate, both in position and size, between the ophthalmic nerve and the mandibular nerve.
