Anatomia Microcirúrgica e abordagens ao seio cavernoso

The cavernous sinus is one of the most complex regions of the human body and can be affected by several diseases. Currently, several types of treatment can be used in the management of diseases in this region. The anatomical knowledge is essential to establish the best management. Our goal is to present the microsurgical anatomy of the cavernous sinus, its surgical approaches (including the endoscopic endonasal approach), the correlation of radiological anatomy, including an initial series of cases. The anatomic features are presented by the conventionaland stereoscopic anaglyphic method. The neurovascularstructures of the cavernous sinus and its dural and bony relationships, triangles and the walls of the skull base related to it are presented with. We discuss the cranio-orbital zygomatic, transpetrosal, zygomatic and endonasal endoscopic approaches; MRI studies also show the anatomical structures, including illustrative cases.
