The distribution of auricular acupoints can be grouped together to make them easier to remember. This is no different than location, angle and depth of regular acupoints. While I learned ear and scalp microsystems in great detail, I preferred going deep into body-acupuncture theory and practice. I was, however, reviewing the ear today and wanted to share these groups. Maybe it will help you remember, too!
Points on ear lobe (lobule): related to head & face
Points on scapha: related to upper limbs
Points on antihelix and 2 crura: related to trunk and and lower limbs
Points on cymba and cavum conchae: related to internal organs
