An Miān (N-HN-54) is located behind the ear at which relation?

• A. Between Jīnjīn and Yùyè on the tongue frenulum
• B. Behind the ear, midway between Fengchi GB-20 and Yìfēng SJ-17
• C. 2 cun above DU-14 on the neck
• D. Below L5 on the back midline

Answer: (B)

An Miān is one of the head/neck extra points located behind the ear. Its position is described as the point behind the ear at the midpoint of the line between Fengchi (GB-20) and Yìfēng (SJ-17). Fengchi is down at the base of the skull in the hollow between the sternocleidomastoid and trapezius, while Yìfēng sits just behind the earlobe. The halfway point between these two landmarks places An Miān behind the ear, not on the tongue frenulum, the neck higher up, or the back midline. This precise relation to known landmarks is what makes this description the best.
