Abstract:
The current nomenclature of Chiari malformations includes the standard designations, Chiari 1-4, which were described by Hans Chiari in the late nineteenth century, and more recent additions, Chiari 0, 0.5, and 1.5, which emerged when the standard nomenclature failed to include important anatomical variations. The authors describe these entities and propose that to best optimize clinical care and research, it would be wise to place less focus on the eponyms and more effort on developing a descriptive or pathophysiological nomenclature.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
