The nasion (nā′zē än′) is the intersection of the frontal bone and two nasal bones of the human skull. Its manifestation on the visible surface of the face is a distinctly depressed area directly between the eyes, just superior to the bridge of the nose.[1] It is a cephalometric landmark that is just inferior to the glabella.
