In such cases, a burr is necessary to remove enough bone to create a lacrimal–nasal ostium. This article illustrates the normal anatomy of the base of the skull, orbit, pituitary and some other cranial nerves. The vascular anatomy of the orbits can be well demonstrated on high-resolution MRI and CT angiography (CTA).
