A morphometric and morphological analysis of the foramen magnum, hypoglossal canal and occipital condyles in a select South African population

Folia Morphologica
BACKGROUND: The foramen magnum is a centralised structure found at the base of the skull. This orifice is a passageway that allows secondary structures, such as the medulla oblongata and meninges, to pass through.

Chiari I Malformation: Review and Update of Current Treatment Options

Clinical Anatomy, EarlyView.
ABSTRACT The pathophysiology of Chiari malformation type I (CM‐I) is complex, involving structural abnormalities at the craniovertebral junction that result in herniation of the cerebellar tonsils through the foramen magnum. In this study, we aim to present and evaluate current treatment options for CM‐I, with a focus on evidence‐based clinical ...
