Morphological and Morphometric study of Jugular Foramen in human dry skull of Eastern Indian origin: An Anatomical Investigation

Background: Jugular foramen (JF) is one of the complex foramen present in base of skull. It varies in shape and size from side to side in same cranium, in different cranium and in different races. It is associated with many diseases of posterior cranial fossa and many skull base surgeries are being...

Description
Summary:Background: Jugular foramen (JF) is one of the complex foramen present in base of skull. It varies in shape and size from side to side in same cranium, in different cranium and in different races. It is associated with many diseases of posterior cranial fossa and many skull base surgeries are being carried out by drilling the skull bone around JF for better exposure. Aim and objectives: The present study aims to carry out the morphological and morphometric analysis of jugular foramen of skulls of eastern Indian origin. Materials and Methods: The study was carried out on 100 JF of 50 dried human skulls. Anteroposterior(width), medio-lateral diameter(length) of JF, width and depth of the jugular fossa were measured. Mean and standard deviation of different measurements of left and right side were statistically analysed by student’s t-test. Presence of dome and septum were also studied. Results: The mean of all the measurements are more on right side than left side but it is statistically insignificant (p>0.05). Bony septum was found in 76% cases on left side and 60% on right side. Complete septation wasn’t found in our study. Domed roof was present in 66% cases on right side as compared to 52% on left side. Conclusion: Shape and size of JF may vary due to different size of internal jugular vein and it’s superior bulb. These variations can be due to constitutional, racial or genetic. This anatomical knowledge of JF may help the neurosurgeons, ENT surgeons and radiologists during their clinical exploration.
