Craniofacial indices provide an objective anthropometric basis for the assessment of extant ethnic-based morphological variation in facial norms and related features. Cephalic index (CI), the continuous variable that defines the linear craniometric relationship between head breadth and head length, carries a significant relevance in that direction. The current descriptive study applies its’ aim at generating gender-specific mean CI values for a sample population of 200 pure breed Urhobo indigenes resident in the Nigerian Niger-Delta region.
The male study population of 150 Urhobo subjects presented a mean CI of 81.5±5.2, as against 84.9±3.1 in the female sample population of 50 participants; these gender differences were statistically significant on t–test inferential analysis. Undoubtedly, obtained study results as presented, with its comparative relevance, would stimulate substantial interest among physical anthropologists, practitioners of cosmetic surgery and other medical experts concerned with the development and application of scientific knowledge related to physical human variability.
