Which acupoint is known for being located directly level with the apex of the ear when the ear is folded forwards?

The acupoint known for being located directly level with the apex of the ear when the ear is folded forwards is Sanjiao 20 (SJ-20). This point is found in the region of the head, specifically around the temple area, which is anatomically significant in acupuncture. SJ-20 is considered useful for issues related to the ear, as well as conditions like headaches and jaw pain due to its location and associated meridian pathways.

Understanding the anatomical landmarks is crucial in acupuncture practice. When the ear is manipulated and brought forward, the apex or tip of the ear aligns with SJ-20, allowing practitioners to locate this point effectively. This relationship helps reinforce the point’s relevance in treating conditions affecting the ear and nearby structures.

In contrast, while the other points listed may have their therapeutic applications, they do not specifically align with the anatomical feature described in the question. SJ-22, GB-1, and GB-5 have different anatomical references and clinical uses, which do not share the same distinctive relationship between the acupoint location and the apex of the ear when folded.
