Angular Photogrammetric Analysis of the Facial Profile of the Adult Bangladeshi Garo

Abstract

The analysis of facial soft tissue from the photographic records gives information about the standard normative values of different facial parameters of a specific population group, helps in the diagnosis of any abnormalities of face and also helps for the treatment plan of patients undergoing orthodontic treatment or facial plastic surgery. The aim of the present study was to measure some craniofacial angles of the Bangladeshi Garo males and females on standardized facial profile photographs and compare them with each other and with norms of different ethnic group proposed by the other investigators. The study was carried out with a total number of 100 Christian Garo adult male and female subjects. Statistical analysis showed that the females had significantly higher values than the males in three facial angles (p < 0.05): the nasofrontal angle (G-N-Pro, females = 137.97˚ ± 4.80˚; males = 129.57˚ ± 7.96˚), the nasomental angle (N-Prn-Pg, females = 132.79˚ ± 5.10˚; males = 129.75˚ ± 7.32˚) and the angle of facial convexity (G-Sn-Pg, females = 169.26˚ ± 4.43˚; males = 158.65˚ ± 12.17˚) but no differences between the nasofacial (G-Pg/ N-Prn) and nasolabial angle (Cm-Sn-Ls). Findings from the present study might help to establish a distinct facial profile trait for the Garo population.

Angular Photogrammetric Analysis of the Soft Tissue Facial Profile of Iranian Young Adults

“…Consistent with our study, Ferdousi et al found no statistically significant gender differences in the nasolabial angle.Furthermore, we found that the average angle of facial convexity in this study (female subjects = 169.26 ± 4.43 degrees; male subjects = 158.65 ± 12.17 degrees) was similar to our study. Whereas, we found potentially substantial differences in the average values in the nasofrontal angles between our study (145 -149 degrees) and Ferdousi et al (130 -138 degrees) (26). In a sub-population of young Igbo adults, Loveday et al (7) showed significant gender differences in nasofrontal and cervicomental angles.…”

The Distribution of Facial Profile Photogrammetry of High School Students in Medan

“…In a facial profile study by Ferdousi AM, et al, on Bangladesh Christian Garo population, the angle of facial convexity was found to be higher in females (169.26° ± 4.43°) than males (158.65° ± 12.17°), similar to that in the North Indian population and White European population. The higher convexity in females could be explained by the fact that in general the facial contours of females were softer than those of males, especially in the area of the nose, lips and chin [26].…”
