Angular Photometric Analysis of Gokana Adult Females in Rivers State

It is an accepted fact that the facial norms for different ethnic groups can differ widely. So there is need to establish specific anthropometric data for facial study for population with different ethnic background. The aim of this study is to determine the facial characteristics of adult Kalabari females using photometric facial analysis. Standardized photographic records were taken from 134 adult Gokana females in both frontal and lateral views at a distance of 120 cm in a natural head position (NHP) and analysed using Pro Image Analyser. The mean ±standard error of mean of the nasofrontal angles, nasolabial, nasofacial, nasomental and mentocervical angles are 140.6±0.86º, 85.7±1.45º, 29.5±0.44º, 132.5±0.68º and 90.7±0.94º respectively. Some unique facial features such as less chin, less prominent nose and glabella were observed in this population of study when compared with the some other populations. The results of this study could be useful to clinicians, orthodontics, facial surgeons and forensic scientists.
