Abstract

Introduction: The jugular foramen (JF) is larger irregular curved foramen situated in the skull base which transmits major neurovascular structures especially internal jugular vein. Variations in JF are more common in the same or different crania, races and sexes. The knowledge of detailed anatomy is therefore necessary to conduct microsurgeries in and around these foramina.
Material and Methods:The present study was conducted on 40 adult dried human skulls having 80 jugular foramen procured from Department of Anatomy at Kodagu Institute of Medical Sciences, MadikeriWe have observed and metric measurements of the anterioposterior and mediolateral diameter of jugular foramen, width and depth of the jugular fossa were taken by using digital vernier callipers and the data were tabulated, analysed and compared.
Results:The dimensions of JF and Jugular fossa were larger on right side. Out of 40 skulls, bilateral complete septations were found in 6 (15%) skulls and bilateral partial septations were found in 4 (10%) skulls. Two septations on left side were observed in only one skull. The mean±SD of width and depth of jugular fossa were 7.61±1.95 mm and 8.63±2.58 mm on left and 9.18±1.65 mm and 10.39±3.33 mm on right side respectively. A dome indicating the prominent superior jugular bulb were found in 69 (86.25%) jugular fossa, of which 29 (72.5%) were bilateral.
Conclusion: The variations could be due to constitutional, racial or genetic factors. Thus the present study is important for the surgeons in dealing with space occupying lesions in and around the foramen.

Keywords:Skull, Jugular foramen.
