ANTHROPOMETRIC STUDY OF THE AURICULAR DIMENSIONS IN ADOLESCENTS AMONG THE SOUTH-SOUTH NIGERIANS (original) (raw)

This study was aimed at documenting the auricular dimensions of Nigerians in the South-South and to find out if it will exhibit sexual dimorphism. 500 subjects were randomly selected, (250 males and 250 females) .Vanier callipers was used to carry out the measurement which are :Auricular length(AL), Auricular width (LW),Lobular length(LL),Lobular width (LW), Attachment length(ATTL). The data obtained was analyzed using independent sample t-test. The mean results obtained were as follows: males: AL(R-5.5724 ± 0.021, L-5.5572 ± 0.022)cm AW(R-2.9804 ± 0.022,L-2.9706 ± 0.023)cm, LL(R-1.4496 ± 0.014, L-1.4248 ± 0.014)cm, LW(R-1.7640 ± 0.027, L-1.7928 ± 0.027)cm, ATTL(R-4.5496 ± 0.022, L-4.5608 ± 0.025)cm, and females: AL(R-5.5836 ± 0.023, L-5.5720 ± 0.025)cm, AW(R-2.8412 ± 0.023,L-2.8526 ± 0.026)cm, LL(R-1.5116 ± 0.014, L-1.4820 ± 0.013)cm, LW(R-1.7820 ± 0.021, L-1.7576 ± 0.022)cm, ATTL(R-4.5828 ± 0.024, L-4.5976 ± 0.026)cm. The difference in the auricular length (AL), lobular width (LW), and attachment length (ATTL) of males and females showed no statistical significant difference (P˃0.05). But the difference in the auricular width of males and females was statistically significant (P˂0.05), with males showing greater auricular width on both sides when compared with females suggesting sexual dimorphism. The lobular length showed sexual dimorphism on both sides with females having greater values than males, this difference was statistically significant (p<0.05). However there was no statistical difference between the right and left auricular dimensions in males (P˃0.05). There was also no statistical difference between the right and left auricular dimensions in females (P˃0.05). This study presents metric data of
