ANGULAR PHOTOGRAMMETRIC ANALYSIS OF FACIAL PROFILE OF IGBOS OF ANAM COMMUNITY OF NIGERIA

Abstract

Beauty is most expressed by the face than any other part of the body. The beauty and uniqueness of the face is determined by the sizes and shapes of various parts of the face and various facial angles. The aim of this study was to characterize the angular facial profiles of the Indigenes of Anam, for application in aesthetics. It was a cross sectional study. Sample size was 500 (250 males and 250 females) and age range was between 18 to 40 years. Facial photographs were taken with a digital camera. A computer software was used to measure the following angles: nasofrontal (NF) angle, nasomental (NM) angle, nasofacial (NFa) angle, nasolabial (NL) angle and angle of facial convexity (AFC). Means of the angles were determined and test of significance was done using student t - test. The mean age for the sample was 22.09 ± 0.46 years (females) and 23. 87 ± 0.44 years (males). Females had significantly higher values ​​than males in NF angle (females-134.00 , males-131.0 0 ), NM angle (females-129.0 0 , males-127.0 0 ), NL angle (females-78.9 0 , males-73.4 0 ) and AFC (females-165.0 0 , males-163.0 0 ). There was no significant sex difference in the value of NFa angle (females-40.9 0 , males-40.4 0 ). Some of the facial angular parameters correlated with each other in males and females but the strength of the correlations were small. This study shows that there was significant sex difference in NF, NM, NL angles and AFC, but not in NFa angle. There was mild correlation between the various facial angles in both sexes.
