Transcranial View of the Optic Canal Region

Surgical Correlation

Tags

Transcranial view of the optic canal region. The dura of the limbus of the sphenoid separates the planum sphenoidale from the prechiasmatic sulcus and extends laterally to form the falciform ligament. This ligament forms the posterior-most aspect of the roof of the optic canal. The anterior clinoid process forms the lateral wall of the optic canal, which is not accessible from an endonasal approach. The bony roof of the optic canal, however, is reachable from the endonasal route to facilitate removal of the lateral extension of a meningioma beyond the level of the internal carotid artery (ICA) and optic nerve. (Image courtesy of JC Fernandez-Miranda)
