The knowledge of the dimensions of the external ear is important in the understanding of the physiognomy and aesthetics of the human body. Recent indications have also demonstrated experimentally that the pinnae perform an acoustical transformation essential to localization in human hearing. Standardized measurements of the longitudinal and transverse diameters of the normal pinna were measured in 148 male and female Nigerian Igbos of the Southeast zone, between the ages of 6 and 70 years. The subjects studied were selected to meet the inclusion criteria and were grouped according to age and sex. The data were analysed using the SPSS version 10.0. The mean length of the pinna for males (n = 101) for right and left side were 5.98 and plusmn; 0.3929 and 6.02 and plusmn; 0.2892 respectively.. The mean width for right and left were 3.182 and plusmn; 2.761 and 3.220 and plusmn; 0.1580 respectively. There were no statistical difference (p and lt; 0.05) in the lengths and widths between the right and left sides of the males in the population under study. The means for lengths of right and left female pinna were 5.94 and plusmn; 0.2466 and 5.96 and plusmn; 0.2671 respectively. The means for the width of right and left female pinna gave 3.02 and plusmn; 0.1984 and 2.98 and plusmn; 0.1357 respectively. In all cases there were no statistical differences between the left and right sides as well as in the age categories. Overall data showed showed slight sex differences which was not statistically significant.
