Abstract:
:The anatomy of the skull base is complex. In the infant and child, the complexity is magnified by the numerous sutures, synchondroses, and normal variants that are present. In this article, the normal anatomy of the skull and skull base is presented using radiographs, computed tomography, and magnetic resonance imaging. Specific attention to the postnatal development of each portion is given.
