Number is total number of jugular foramina analyzed in the study. APD, anteroposterior diameter; LMD, latero-medial diameter; TLMD, total latero-medial diameter (a sum of LMD posterolateral part and LMD anteromedial part). a)Values described as mean±SD. The other linear measurements were described as median±interquartile range (IQR).
