In adults the lateral rim of the jugular foramen lies 14.1 (8–19) mm from the inferior margin of the porus acusticus on the right side and 15.5 (9–21) mm on the left side. Hence:
The mean distance is shorter on the right side, probably due to the fact that the jugular foramen is better developed on that side.
This distance shows a very large range of individual variation.
