Emphasis is placed on the anterior branch of the middle meningeal artery, which runs beneath the pterion and must be carefully preserved. The Sylvian fissure is exposed along with the following cortical structures: inferior frontal gyrus, superior temporal gyrus, and parts of the middle frontal gyrus and middle temporal gyrus.
