| Introduction The clivus is a bony structure formed by the fusion of the basioccipital and basispheniod bone at the sphenooccipital
synchondrosis. This downward sloping structure from the dorsum sellae to the foramen magnum is derived from mesoderm and
ectoderm properties.
Methods This comprehensive review of the clivus will discuss its basic anatomy, embryology, pathological findings, and surgical
implications. The clivus is an endochondral bone, formed under two processes; first, a cartilaginous base is developed, and it is
secondly reabsorbed and replaced with bone. Knowledge of its embryological structure and growth of development will clarify
the pathogenesis of anatomical variants and pathological findings of the clivus.
Conclusions Understanding the anatomy including proximity to anatomical structures, adjacent neurovasculature properties, and
anatomical variants will aid neurosurgeons in their surgical management when treating pathological findings around the clivus. |
