World scientists are using facial morphometry as a reconstructive option in the treatment of patients and ethnic differentiations. Hence, the authors aimed to study the naso-facial dimensions of northern population in Nigeria.
About 500 subjects (Igede, n = 260 and Idoma, n = 240) were recruited from schools in the Benue-Plateau valley in 2014-2015 academic session. Notable parameters measured using vernier caliper were upper facial length, lower facial length, total facial indices, nasal length, nasal width, and nasal indices. Also, stature was measured to the nearest centimeters with stadiometer.
Taller Idoma males than Igede males (169.25 ± 8.92, 167.13 ± 8.99), and taller Igede females than Idoma females (164.57 ± 8.77, 163.45 ± 8.94). The mean facial indices of Idoma subjects showed 97.89 ± 8.53 and 97.82 ± 8.11 with nasal indices of 77.77 ± 7.34 and 80.42 ± 7.53, whereas Igede subjects showed 96.88 ± 8.61: 97.83 ± 8.36 with nasal indices of 75.59 ± 7.45 and 77.55 ± 0.21. Both ethnic groups showed dominance of the leptoprosopic face type and mesorrhine nose type. All R2 values appeared to be above 0.5% (P < 0.05), where Igede males and females were 0.72, 0.71: 0.82, 0.81, and 0.69, 0.65 and 0.72, 0.73 for stature with total facial indices, and nasal indices respectively.
Facial and nasal types serve as good predictors of stature, important for dimorphic and ethnic classifications in time of forensic needs.
世界各地的科学家正在将面部形态测量法作为治疗患者和区分种族的一种重建方法。因此，作者旨在研究尼日利亚北部人群的鼻面部尺寸。
2014 - 2015学年期间，从贝努埃 - 高原山谷的学校招募了约500名受试者（伊格德族，n = 260；伊多马族，n = 240）。使用游标卡尺测量的显著参数包括上面部长度、下面部长度、面部总指数、鼻长度、鼻宽度和鼻指数。此外，使用身高计将身高测量到最接近的厘米数。
伊多马族男性比伊格德族男性更高（169.25 ± 8.92，167.13 ± 8.99），伊格德族女性比伊多马族女性更高（164.57 ± 8.77，163.45 ± 8.94）。伊多马族受试者的平均面部指数分别为97.89 ± 8.53和97.82 ± 8.11，鼻指数分别为77.77 ± 7.34和80.42 ± 7.53，而伊格德族受试者的面部指数分别为96.88 ± 8.61和97.83 ± 8.36，鼻指数分别为75.59 ± 7.45和77.55 ± 0.21。两个族群均以窄面型和中鼻型为主。所有R²值似乎都高于0.5%（P < 0.05），其中伊格德族男性和女性的身高与面部总指数、鼻指数的R²值分别为0.72、0.71、0.82、0.81以及0.69、0.65和0.72、0.73。
面部和鼻型是身高的良好预测指标，在法医需求时对于两性和种族分类很重要。
