Comparative Study of Nasofacial Angular Parameters of Hausa and Igbo Subjects Resident in Nigeria

Abstract

This study aims to compare the Nasofacial angular parameters for Hausa and Igbo ethnic groups in Nigeria. The study design was a cross-sectional design which catalogued values of the anthropometric features of adult Nigerian males using anthropometric standards for the reconstruction of a three – dimensional negroid gross anatomical modelling. The methodology used was adult males between the ages of 18 and 40 years of Igbo and Hausa Tribes residing in Imo and Kano states of Nigeria. The results are, the mean parameters of the descriptive statistics for Hausa Nasofacial parameters are as follows; NasoLabial angle (NLA) =79.44, Nasomental angle (NMA) = 139.51, NasoFacial angle (NFcA) = 20.63, MentoCervical angle (MCA) = 131.61, NasoFrontal angle (NFA) = 83.47. The mean parameters of the descriptive statistics for Igbo Nasofacial parameters are as follows; NasoLabial angle (NLA) =49.40, Nasomental angle (NMA) = 81.32, NasoFacial angle (NFcA) = 32.07, MentoCervical angle (MCA) = 7.89, NasoFrontal angle (NFA) = 103.16. In conclusion, the study's findings contribute valuable data to the understanding of ethnic variability in facial parameters, emphasizing the need for population-specific reference data in both medical and technological fields. These results are especially relevant in the context of Nigeria, a nation characterized by its ethnic diversity, where such anthropometric data can play a pivotal role in various applied sciences.
