Background: Craniometric study is an important fraction of anthropometry that can be employed in the determination of cranial capacity of an individual. It indirectly reflects the volume of the brain and predicts mental ability. The aim of this research is to asses, compare and contrast sexual dimorphism in craniometric parameters and its relationship to intelligence, among Igbos resident in Enugu state. Materials and method: Two hundred and seventy-five (275) persons (148 males 127 females) aged 16-34 years were randomly selected. Cranial dimensions (cranial length, width and height) and weight and height of the individuals were taken and analyzed using descriptive statistics, Pearson correlation coefficient and chi square test of independence. Result: Cranial capacity has no significant correlation with intelligence quotient for all subjects (p>0.05). The male subjects in our cohort were observed to have higher cranial length, breadth, height, cranial capacity and intelligence quotient than the females. Conclusion: Findings from this study show that sexual dimorphism exists in craniometric parameters and there is no significant relationship between craniometric parameters and intelligence quotient among Igbos resident in Enugu metropolis. The findings from this study could aid forensic facial reconstruction and portrait sculpture. Hence, it would be found useful by the maxillofacial and plastic surgeons and even forensic experts.
Author Keywords: Craniometry, craniometric parameters, intelligent quotient, sexual dimorphism, Igbos.

Abstract
Background: Craniometric study is an important fraction of anthropometry that can be employed in the determination of cranial capacity of an individual. It indirectly reflects the volume of the brain and predicts mental ability. The aim of this research is to asses, compare and contrast sexual dimorphism in craniometric parameters and its relationship to intelligence, among Igbos resident in Enugu state. Materials and method: Two hundred and seventy-five (275) persons (148 males 127 females) aged 16-34 years were randomly selected. Cranial dimensions (cranial length, width and height) and weight and height of the individuals were taken and analyzed using descriptive statistics, Pearson correlation coefficient and chi square test of independence. Result: Cranial capacity has no significant correlation with intelligence quotient for all subjects (p>0.05). The male subjects in our cohort were observed to have higher cranial length, breadth, height, cranial capacity and intelligence quotient than the females. Conclusion: Findings from this study show that sexual dimorphism exists in craniometric parameters and there is no significant relationship between craniometric parameters and intelligence quotient among Igbos resident in Enugu metropolis. The findings from this study could aid forensic facial reconstruction and portrait sculpture. Hence, it would be found useful by the maxillofacial and plastic surgeons and even forensic experts.
