Background: The human ear is unique to individuals, and ear prints, like fingerprints, are discrete enough to distinguish identical twins. Therefore, the external ear could be used to identify both living and deceased individuals. Therefore, this study aimed to evaluate the stature and sexual dimorphism of the external ear using various morphometric parameters and morphological features for forensic identification. Methods: This study included 40 participants. Various measurements were taken and the morphological features of both the right and left ears were noted. The results were statistically analyzed. Results: In males and females, the most common shape was oval, and the ear lobe was free. The most common shape of the ear lobe in males was arched, while in females, it was triangular. In males and females, the most common form of the helix was the concave marginal. In males, the most common shape of the tragus was round, whereas in females, it was long. In males and females, the most common shape of Darwin’s tubercle was enlarged. It was seen that the right lobe width showed perfect separation, indicating its potential as an extremely reliable predictor. It was noted that in females, the strongest correlation with height was with the ear inclination angle on both sides. Conclusion: The results of this study can help forensic anthropologists identify the sex and stature of a person from various ear measurements.背景：人类耳部具有个体独特性，耳纹（ear prints）与指纹类似，其离散性足以区分同卵双胞胎。因此，外耳可用于识别活体与已故个体。本研究旨在通过多种形态测量参数（morphometric parameters）与形态特征，评估外耳的身高相关性与性别二态性（sexual dimorphism），以服务于法医身份识别（forensic identification）。 方法：本研究纳入40名受试者，对其双耳开展多项形态测量，并记录双耳的形态特征，随后对结果进行统计学分析。 结果：无论男性还是女性，最常见的耳形均为椭圆形，且耳垂均为游离型。男性最常见的耳垂形态为弓形，女性则为三角形。无论男女，耳轮（helix）最常见的形态为缘凹型。男性最常见的耳屏（tragus）形态为圆形，女性则为长形。无论男女，达尔文结节（Darwin's tubercle）最常见的形态为增生型。研究发现，右耳垂宽度具有极佳的区分度，表明其可作为极为可靠的预测因子。此外，女性的身高与双侧耳倾角均存在最强相关性。 结论：本研究结果可协助法医人类学家通过多项耳部测量数据，推断个体的性别与身高。
