Which acupoint is located behind the earlobe?

The correct acupoint located behind the earlobe is SJ-17, known as "Yifeng" or "Wind Screen". This point is found in the depression between the mandible and the mastoid process, just posterior to the earlobe. SJ-17 is commonly used in treatments related to conditions affecting the ear and surrounding areas, including tinnitus and ear infections, as well as for headaches.

Understanding the other acupuncture points in relation to their anatomical locations helps clarify why SJ-17 is the correct answer. SJ-20, for instance, is situated above the ear in a different position, while GB-1 is located at the outer canthus of the eye. GB-5, on the other hand, is at the temple area and is not associated with the earlobe, highlighting that SJ-17 is indeed the distinctive point situated directly behind the earlobe.
