耳穴在耳郭的分布有一定的规律，耳郭好像一个头部朝下臀部朝上的倒置胎儿。其规律是：与头面部相应的穴位分布在耳垂或耳垂附近，与上肢相应的穴位分布在耳舟，与躯干和下肢相应的穴位分布在对耳轮上、下脚与内脏相应的穴位多集中在耳甲艇和耳甲腔；与消化道相应的穴位在耳轮脚周围环形排列 (图1)。

The distribution of ear acupuncture points on the auricle follows a certain scheme. The auricle is compared to an inverted fetus with the head down and the buttocks towards the top. The pattern is as follows: points corresponding to head and face are distributed over the earlobe or near it. The points corresponding to the upper limbs are located at the scapha. Those associated with the trunk and lower limbs are spread across the superior and inferior crus of antihelix. As for the points related to internal organs, they are mostly concentrated at cymba conchae and cavity of concha. The points correlated with the digestive system are lined up around the helix crus (Fig. 1).
