The external occipital protuberance is a prominence around the center of the parietal surface of the squama that diverges significantly in its vividness and protrusion, and functions as the connection of the ligamentum nuchae. The superior nuchal lines spread laterally toward the temporal bone on either side of the protuberance The external occipital protuberance (EOP) size was defined as the distance from the most superior point of the EOP (origin) to a point on the EOP that is most distal from the skull. To avoid ambiguity, the threshold for recording the size of an EOP was set at 5 mm, and an EOP was classified as enlarged if it exceeded 10 mm. Reliability testing was also undertaken. Results indicated that an EEOP was present in 41% of the total population, with 10% of all participants presenting with an EOP. External occipital protuberance is a midline bony prominence in the occipital bone that ligamentum nuchae and trapezius muscle attach to its tip. The tentorium cerebelli attaches to its internal surface.
