Photometric Facial Analysis of Soft Tissue Profile of Okrika Adults

Abstract

Aim: The aim of this study was to determine the facial norms of the Okrika people by photometric analysis. Study Design: This study is designed to evaluate facial aesthetics and provide photogrammetric standards for male and female Okrika adults. Place and Duration of Study: The population of study was drawn from natives, who reside within the community centers of Okrika town in Rivers state, south- south, Nigeria between the months of June to December, 2012. Materials and Method: Standardized photographic records of 245 (comprising 160 males and 85 females) subjects in the natural head position were taken using a digital camera. Measurements taken included; Nasal length, nasal width, nasal tip projection, upper nasal length, lower nasal length and nasofrontal angle. Analysis was done using a software tool for facial analysis and Z-test. Result: Results showed that the mean of the nasal width was 33.3±0.54mm for males, nasal length 41.8±0.74mm, nasal tip projection 12.2±0.26mm, upper nasal height 31.9±0.56mm, lower nasal height 10.8±0.52mm and Nasofrontal angle 134.13±0.85º while for the females it was 29.9±0.39mm for nasal width, nasal length 38.2±0.49m, nasal tip projection 10.7±0.23mm, upper nasal height 28.0±3.01mm, lower nasal height 10.3±0.19mm, Nasofrontal angle 137.68±5.63º. Significant differences were observed in the parameters measured (P=.05). Conclusion: This study could be useful in orthodontics and facial plastic surgery.
