The periosteal dural layer, which forms the anterior wall of the cavernous sinus, is being retracted superiorly. The meningeal or inner dural layer forms the medial wall of the cavernous sinus. The cavernous segment of the ICA has been partially exposed. Meningeal attachments run from the inner dural layer to the cavernous ICA. (Image courtesy of JC Fernandez-Miranda)
