In this study, a total of 125 female and 175 male adult human skulls f
rom Central Anatolia were examined. The incidence and localization of
the rare occipital foramen found on the squama of occipital bone were
investigated. This foramen has significant importance during suboccipi
tal craniotomies since it transmits the occipital emissary vein. In th
e present study, the occipital foramen was found in 8 (2.6%) skulls. I
ts location was closer to the foramen magnum but not to the external o
ccipital protuberance.
