The jugular foramen (JF) lies between the occipital bone and the petrosal portion of the temporal bone, and it allows for the passage of important nervous and vascular elements, such as the glossopharyngeal vagus and accessory nerves, and the internal jugular vein. Glomic tumors, schwannomas, metastatic lesions and infiltrating inflammatory processes are associated with this foramen, which can account for injuries of related structures. Variatons of the JF were already reported regarding shape, size and laterality in one only skull, besides differences related to sex, race and laterality domain, which makes the study of these parameters in the population of southern Brazil significant. Objective: this paper wants to conduct the morphometric analysis of the JF of 111 dry skulls belonging to males and females. Results: the latero-medial the anteroposterior measurements showed significant differences when genera were compared and side was compared, respectively. Of the total amount of the investigated skulls, 0.9% showed a complete septum on both sides; 0.9% showed incomplete septum, and 83.8% lacked the septum. The presence of a domed bony roof was noticed in 68.5% of skulls on both sides. Conclusion: the obtained results presented variations regarding some parameters when compared to previous studies, thus making it evident the significance of race in the morphometric measurements and characteristics of the JF, besides the relevance of studying the kind of impairment which can jeopardize important functions, as the cardiac innervation of the vagus nerve.
