Abstract


Objective: The objective of this study was to determine the morphometric variation between male and female jugular foramen using dried human skulls obtained in two Nigerian states.'
Methods: A total of ninety-three (93) dry human skulls were obtained from the osteology collection of the Department of Anatomy, University of Ilorin, Kwara state and Ladoke Akintola University Ogbomosho, Oyo state, Nigeria for this study. Using a digital Vernier caliper various morphometric features were measured.
Results: The mean right lateromedial distance was 14.69 (±2.31) mm and 13.78 (±1.95) mm for male and females respectively, the mean left lateromedial distance was 14.40 (±2.34) mm and 14.52 (±2.40) mm. Complete septa in males and females were 31.7% and 9.1% while incomplete septa in males and females 35.0% and 39.4% respectively.
Conclusion: There was no significant difference between the jugular foramen of both male and female skulls. The presence of complete septa is more in males while females has more of incomplete septa. The presence of dome, septa and dome height in both sexes were not sexually different from each other.

Keywords: Jugular foramen, morphometric, dome, septa, vernier caliper.
