Background: The jugular foramen is an intricate anatomic area in the skull base owing to the fact that there are considerable differences in its dimensions bilaterally as well as in different cranial bases. Furthermore, it remains to be a difficult area to access for the neurosurgeon. Hence, knowledge of the precise anatomy and dimensions of the jugular foramen is imperative. Materials and Methods: 100 (male-59; female-41) dry adult human skulls were obtained from the Dept. of Anatomy and Forensic Medicine & Toxicology of Grant Medical College in Mumbai, India. A millimetric sliding vernier caliper was used to measure the distances. The statistical analysis was done using the statistical package Graph Pad Prism 5 software.
Results: The sagittal diameter of the jugular foramen (SDJF) & the transverse diameter of the jugular foramen (TDJF) on the right side was significantly greater than that of the left side (p value: SDJF- 0.0001, TDJF- 0.045) for all samples studied. For all the samples studied there was a significant correlation between the right and left sides. (r values- SDJF-0.284, TDJF-0.474). In the male skulls SDJF was significantly greater on right side (p<0.0001) whereas TDJF was non significantly greater on the right side (p=0.33). For the female skulls both the parameters were significantly greater on the right side (p value: SDJF- p<0.0001, TDJF- p=0.03). In the gender comparative analysis, SDJF in the male skulls was greater than the female skulls on both the sides but the difference was non significant ( p value: right side-0.56, left side-0.12). TDJF in male skulls was also greater than the female skulls and the difference came out to be significant on both sides ( p value: right side-0.03, left side-0.0003). The occurrence of dome (49-bilateral, unilateral-35, 16-absent) and septation (58-absent, 10-complete, 32-partial) in the jugular foramen was also ascertained.
Conclusions: The study gives a useful perspective about the morphology of the jugular foramen in a subset of population in the western Maharashtra region of India. Studies with larger sample size are required to corroborate these findings and its relevance in a clinical setting.
