Foramen Venosum: Prevalence, Patency and Correlation with Cephalic Index

The foramen venosum (FV) is an anatomical structure situated at the base of the skull, generally posteromedial to the foramen rotundum and anteromedial to the foramen ovale. Its prevalence and patency may be related to the shape of the skull. The objective of this study was to verify the prevalence...

Its prevalence and patency may be related to the shape of the skull. The objective of this study was to verify the prevalence and patency of the FV and its association with the different skull types. Overall, 143 dry skulls were screened. Of these, 84 were considered to be in an adequate state of conservation and were included in the analysis, which was conducted through a cross-sectional view of the skullcap.

The presence and patency of the FV were evaluated. Overall, 25 % of the skulls were dolichocephalic, 21.4 % sub-dolichocephalic, 26.2 % mesaticephalic, 16.7 % sub-brachycephalic and 10.7 % brachycephalic. Overall, the FV was found in 41.6 % of the skulls (n=35), with this prevalence being greater in the mesaticephalic skulls (50 %; n=11). Patency was 25 % (n=21).
