Anatomical study of the Foramen Venosum and its clinical implications

We examined 178 macerated skulls belonging to individuals of both sexes, black and white. Bilateral or unilateral presence of FV was analysed. The FV-FO and FV-FS distances were measured with a digital caliper. Statistical analysis was done using chi-squared and Student's t tests.ResultsFV was found in 32.02% of the sample. In 23.6% the FV presented bilaterally and in 8.42% unilaterally. FV was more prevalent in white males than in white females. The FV-FO distance was greater in white males than in white females and significantly greater in black females than in white females. There were racial and sexual differences in the FV-FS distance, which was significantly greater in white males than in white females.DiscussionFV is a very frequent anatomical variation, located antero-medially of the FO; it may present either bilaterally or unilaterally, and there is no preference for either side. Specific differences exist in FV distribution by sex and race.
