按随机抽样原则挑选598名恩施土家族人观测了他们的耳廓形态。其耳廓大小适中,大部分为中型或中长中宽型;容貌耳长和容貌耳宽之比约为2:1;一般具有达尔文结(67.73%),以圆结型居多;中青年耳垂主要呈方形或三角形,老年常为圆形或三角形,耳廓外展度多在30°～60°之间;耳廓各径性别差显著,一般随年龄而递增,并出现不同程度差异性。聚类分析表明,恩施土家人耳廓与南方民族相似,与北方民族相距较远。 598 Enshi Tujia people were selected to observe their pinna morphology according to the random sampling principle. The auricle size is moderate, most of them are medium-sized or medium-long medium-wide type; the ratio of the ear length to the width of the ear is about 2: 1; the Darwin knot usually has a ratio of 67.73% The main square or triangle, the elderly are often round or triangular, auricle abduction degrees more than 30 ° ~ 60 °; auricle diameter difference was significant, generally increasing with age, and varying degrees of difference.
