Twenty four cavernous sinuses from tufted capuchin monkey (Cebus apella) were studied throughout gross anatomy, stereoscopic and microscopic serial analysis. The results could show us that the cavernous sinus in monkeys is similar to the other primates, including man. Its pattern is the same as the venous channels located between the dura mater layers. It is attached by trabeculae in the intracavernous portion of the internal carotid artery. Its lateral wall is formed by two layers of connective tissue. The deep layer is continuous with the oculomotor, troclear and ophthalmic sheath nerves. The abducent nerve runs almost all the time between the internal carotid artery and the cranial nerves placed on the lateral wall. Their trabeculae are ensheated by endothelium that divides the sinus in superior, lateral and medial venous spaces in relation to the internal carotid artery. There are communications among them in the intercavernous sinus named anterior, inferior and posterior sinus. The internal carotid artery presents a foreward ascendent retiform course until the anterior segment when it bents abruptly toward the roof of the cavernous sinus. Bundles of the nerve fibers in the trabeculae are greater in number between the internal carotid artery and the abducent nerve. These trabeculae exhibit perikaryon of neurons near the lateral wall and between the abducent and ophthalmic nerves.

KEY WORDS: dura-mater, cavernous sinus, cranial nerves, internal carotid artery, Cebus apella.
