ABSTRACT

Background: The jugular foramen is difficult to understand and to access surgically, Its is difficult to conceptualize because it varies in size and shape in different crania, from side to side in the same cranium, from its intracranial to extra cranial end in the same foramen, because of its complex irregular shape, its curved course, its formation by two bones, and the numerous nerves and venous channels that pass through it. The morphometric measurements of the jugular foramen is very helpful in neurosurgery.

Materials and Methods: A total of 500 jugular foramina were examined from 250 adult dry skulls. The present study was undertaken in adult south Indian skulls from different regions of south India, from different medical colleges. We have observed the length, width and area of the jugular foramina were determined. Metric measurements were taken by using Vernier calipers. The mean standard deviation and range of each dimension and derived index were computed. Right and left side differences were analysed.

Results: In 71.2% of cases the right foramina were larger than the left, in 20.8% of cases the left foramina were larger than the right and in 8% cases they were equal in size on both sides. The mean length of the foramen on the right and left were 24.48+3.17mm and 21.24+4.51mm; the width measured 7.51+1.56mm and 7.16+1.89mm on the right and left respectively; the mean area on the right was 569.41+91.58cmm and on the left 470.40+115.45mm.

Conclusion: There was statistical significance between the two sides in the length and area but there was no significant difference between the two sides in the width. There was a positive correlation between length and width on each side. Statistical analysis did show significant positive correlation between the width and length of the skull and the length of the jugular foramen on both sides.
