CRANIOFACIAL ANTHROPOMETRYA RELIABLE METHOD FOR CLASSIFYING POPULATION: CRANIOFACIAL ANTHROPOMETRY OF ANDONI AND OKRIKA ETHNIC GROUPS IN NIGERIA

The study was directed primarily towards estimating the normal values of head circumference, facial, nasal, maxillary, mandibular, and oro- facial heights of adult Andoni and Okrika ethnic group in Rivers state. The ages ranged from 18- 60 years. The choice of study was deliberate since facial growth changes are minimal at that age range . This study was also aimed at determining if there exist a significant difference in the head circumference and facial dimension between the male and female subjects and also between the two ethnic groups.
