Study of Morphometric Variations in Jugular Foramen and Jugular Fossa of Dried Adult Human Skulls
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 5
Abstract
Introduction: Jugular foramen is most complex irregular bony canal. Many important nerves and vessels are passing through it. Anatomical variation in the course of the nerves and vessels adds more complexity to jugular foramen. Study was done to access morphometric anatomical variations in jugular Foramen and fossa Material and methods: Anteroposterior and mediolateral diameter, depth, width, presence of dom, septations and degree of predominance of Jugular Foramen and fossa in 250 skulls measured by manual vernier caliper Result: Mediolateral diameter of jugular foramen and width of jugular fossa is significantly higher on the right side (p value <.05). Unilateral slit like jugular foramen found in one skull with Anteroposterior (AP) diameter of 2.37 mm. Bilateral complete septation of jugular foramen into two and three compartments is observed in 10% and 4% of the skull respectively. The doomed bony roof is noted in 54.8% of the skull on both sides. Conclusion: The observed variations of jugular foramen are possibly due to constitutional, racial or genetic factors. Knowledge of the observed variation of this foramen is very important for neurosurgeons, radiologists and anthropologists.
