Morphology of the walls of the cavernous sinus of Cebus apella (tufted capuchin monkey)

The morphology of the dura mater and its relatioship with the structures of the cavenous sinus were analyzed in five tuftel capuchin monkeys (Cebus apella) using histological sections, showing that the walls of the cavenous sinus of this species are similar to those of other primates, including man. Except for the medial wall of the cavernous sinus, the remaining walls consist of two distinct dura mater layers. The deep layer of the lateral wall of the cavernous sinus is contiguous to the sheath of the oculomotor, trochlear and ophtalmic nerves. Arterioles, venous spaces, neuronal bodies and nervous fiber bundles are found on this lateral wall.

Estudo micro-mesoscópico da parede lateral do seio cavernoso humano / Micro-mesoscopic study of the lateral wall of the human cavernous sinus

Os autores estudam as estruturas contidas no seio cavernoso humano, tanto em seu interior como na sua parede lateral, através de cortes frontais seriados espessos. Mostram a importância desta parede que é frequentemente usada como via de acesso cirúrgico às afecçoes presentes nesta estrutura venosa da dura-máter.
