Knowledge of the anatomy of this region is extremely important in determining the surgical approach in craniovertebral junction pathologies and tumors. Therefore, the distance of the tuberculum pharyngeum (TP), which is located in the center of this region, to other close and significant anatomical structures is important. This study was conducted using a total of 64 craniums. The width of the pars basilaris at the level of the TP and the distance from the TP to anatomical formations such as opisthion, basion, protuberentia occipitalis externa, condylus occipitalis, canalis caroticus, processus styloideus, foramen stylomastoideum, processus mastoideus and ala vomeris were measured. The difference in measurements between sexes and sides were evaluated. The distances from the TP to opisthion, protuberentia occipitalis externa, condylus occipitalis, left canalis caroticus, proccesus styloideus, foramen stylomastoideum and proccesus mastoideus were statistically higher in males than in females. On the other hand, no significant difference was observed between the sexes in the width of the pars basilaris at the level of the TP and in the distance between the TP to the basion, right canalis caroticus and ala vomeris. There was no statistically significant difference between the distances from TP to condylus occipitalis, canalis caroticus, proccesus styloideus, foramen stylomastoideum, proccesus mastoideus and ala vomeris in both sides and both sexes. In male and female anatomical struc craniums, the pars basilaris ossis occipitalis placed between the vomer and foramen magnum are similar in size. Although the distance of TP to important tures was significantly higher in males than in females, it was observed that the distances of TP to the right and left anatomical structures were symmetrical in all craniums. We think that knowledge of the cranium base morphometry and its bilateral symmetry will guide the interventions to be made here by taking the opposite side as a model.
