The Jugular foramen is large openings which are placed above and lateral to the foramen magnum in the posterior end of the petro-occipital fissure and the anterior part of jugular foramen is allows the cranial nerves IXth, Xth, XIth the direction of the nerves from behind forwards within the jugular foramen and sometimes jugular tubercle it has acted as a groove and later it becomes enter of the foramen. They lie between the inferior petrosal sinus and the sigmoid sinus. Methods: The Antero-Posterior Diameter and Transverse Diameter of the jugular foramen were analysed exocranially for both right and left sides. All the parameters were examined by two methods, Method.1: Mitutoyo Vernier Calliper, Method.2: Image J Software. Results: The present study showed the measurement is statistically significant between the Mitutoyo Vernier Calliper and Image J – Software. Conclusion: The Image J software value is more precise than the Mitutoyo Vernier Calliper values.
