Somatometry of the Head Shape and Nasofrontal Angle of the Aborigines in Gas-Flaring and Non-Gas-Flaring Communities in Bayelsa State, Nigeria

A study on craniofacial indices is key to rhinoplasty planning, head shape evaluation, and ergonomics. This study emphasizes the shape of the head and nasofrontal angle in Gas-flaring and No-gas-flaring communities in Bayelsa state, Nigeria. 1500 adult volunteered participants (760 male and 740 females) between the ages of 18-45 years from seventeen [17] communities in Bayelsa State of Nigeria. Eight [8] gas -flaring such as Imiringi [Civic arean], Obuna [Playground], Brass Island, Oporoma [Town hall], Tebidaba [Open ground], Ogboinbiri [Town hall], Peremabiri [Town hall], Koluama [Open ground], and nine [9] Non-Gas- flaring communities which include Yenagoa, Kaiama [Park], Ekowe [UAC playground], Nangi-Ama [Town hall], Abgura [Town hall], Anyama [School field], Oweikorogha [Town hall] and Amassoma [Town hall], and Ekeremor [Open park]. The study duration is from 20TH March 2022 to 19th October 2022. Nasofrontal Angle, Head Length, Head Breadth, and Cephalic Index were the studied parameters. The results showed, Nasofrontal angle, Head Length, Head Breadth, and Cephalic index as 128.20±0.95, 176.54±1.07, 142.71±1.00, and 124.60±1.12 for males of the Gas –Flaring Communities. The mean values of their female counterparts for Nasofrontal angle, Head Length, Head Breadth, and Cephalic index are 127.21±1.90, 168.82±1.20, 137.82±1.52, and 124.17±1.74. The results of the males from the Non-Gas –Flaring Communities for Nasofrontal angle, Head Length, Head Breadth, and Cephalic index are 125.84±0.77, 173.77±1.13, 142.91±1.15, and 122.24±0.99. The female values are 121.94±1.41, 174.90±1.22, 143.91±1.14, and 121.98±0.95 respectively. In conclusion, both the males and females of the Bayelsans [Ijaws] in South-South Nigeria are broad-headed [Brachycephalic].
