Abstract:

Introduction: The jugular foramen is situated between the lateral part of the occipital and the petrous part of the temporal. The anterior portion of this foramen transmits the inferior petrosal sinus; the posterior portion, the transverse sinus and some meningeal branches from the occipital and ascending pharyngeal arteries and the intermediate portion, the glossopharyngeal, vagus, and accessory nerves. As the neurosurgeons approaches this area, so there is a need to become familiar to prevent complications during neurosurgeries. Hence, the present study was done to examine the anatomy of jugular foramen, including its morphological features and dimensions.

Materials and Methods: In the present study 40  adult dry human skulls were obtained from the Department of Anatomy , JSS Medical College , Mysuru. Digital sliding calipers was used to measure length  and width of jugular  foramen on right and left sides of the skulls.

Results: The mean length and width  of jugular foramina on right side was 1.31±0.35 and   1.04±0.35 respectively . The mean length and width  of jugular foramina on left  side was 1.12±0.38  and   0.98 ±0.30 respectively. Partial septation percentage on right side was 15% and 17.5% on left side. Complete septationpercentage on right side was 12.5% and 10% on left side.

Conclusion: Thorough knowledge of  morphometric findings of jugular foramen will be helpful for neurovascular surgeries.

KEY WORDS: Jugular Foramen, Occipital, Petrous Part, Temporal, Inferior Petrosal Sinus, Vagus, Accessory Nerve.
