Introduction: The vermian fossa (VF) is a shallow depression at the inferior end of the internal occipital crest, which lodges the inferior part of the cerebellar vermis. Published literature describes the VF as having a highly variable incidence and morphology. The present study is aimed to investigate the incidence, morphology, and morphometry of the VF within a select South African population and to conduct a review of the literature regarding this structure. Material and Methods: A total of 100 dry, adult skulls of South African origin were analyzed to determine the morphological and morphometric parameters of the VF. Results: The VF was found to be present in 62% of cases. The shape of the VF was classified as triangular (27%), quadrangular (8%), and atypical (27%). The average length of the VF was 13.78 mm, and the average width was 11.62 mm. The morphometric findings of this study correlate with that of previous studies; however, the incidence of atypical shaped VF (27%) is higher in comparison to previous studies (9.7%). Discussion and Conclusion: The detailed anatomical description of the VF may aid in the study of diseases which cause alterations in the size and morphology of the vermis of the cerebellum as well as in transvermian approaches to tumors within the fourth ventricle. Furthermore, due to the paucity of anatomical descriptions of the VF, a reappraisal of this structure is warranted as it is of prime importance to clinicians operating in or interpreting radiological images of the posterior cranial fossa.
