Özet

The craniovertebral junction is a collective term that refers to the occiput (posterior skull base), atlas, axis, and supporting ligaments. Not only anatomists, but also clinicians are interested in these variations as they cause clinical symptoms.1,2 A median occipital condyle (MOC) can be of various shapes and sizes.3 The basilar (mamillar or papillar) processes are hemisphereshaped bone projections located at the front rim of the foramen magnum. They show a surprisingly high degree of variance; they may be unilateral or bilateral.1 The hypocondylar arch is a more or less complete arch, which is situated extracranially at the anterior margin of the foramen magnum.4 An exostosis anterior to the foramen magnum, which has been described by Taitz,4 is a structure very similar to the MOC, which might represent a manifestation of an occipital vertebra when it is found together with a hypocondylar arch.4 We aimed to investigate the frequency of the MOC, the basilar processes and the hypocondylar arch in adult skulls.
