Core Tip	Even in the year 2026, there is no consensus on a definition nor classification system for Rouvière’s sulcus, despite it being an important surgical landmark. In this systematic review, we used a standardized definition and classification system to extract raw data from 57 articles encompassing 25196 persons and used this to calculate the global prevalence of each variant of Rouvière’s sulcus. These data were compared to the data from a 5-year observational study in our local population. Statistical analyses revealed that the prevalence of Rouvière’s sulcus was significantly greater in the Caribbean population than global prevalence (83.2% vs 76.88%; P = 0.005306). Other unique differences were significantly lower proportions of open-type variants (39.33% vs 56.69%; P < 0001), and greater proportions of slit-type variants (18.26% vs 14.15%; P = 0.033397). These are important differences in the proportion of variants that are of great importance to surgeons practicing in these regions.
