Background:Jugular foramen is one of the foramen at the base of skull lies between the occipital bone and the petrosal portion of the temporal bone. It allows passage of important nervous and vascular elements, such as the glossopharyngeal, vagus 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. Variability in anatomical aspect of jugular foramen has been studied by many workers in different part of the world.
Aims & Objective:Tostudy the variability in shape and size of jugular foramen which has clear cut relationshipwith size of internal jugular vein and presence or absence of dome.
Materials andMethods: Present study has been designed to study on 100 skulls (100×2=200 foramen).
Result: In the study Bilateral presence of dome has been found in 98% of cases. Both unilateral and bilateral completeseptation have been observed. The mean diameters on the right side were more than the left.
Conclusion:The clinical significance of jugular foramen is very important during surgeries. Therefore, the dimensions of jugular foramen is very much necessary.
