After cleaning the area with chlorhexidine, needle aspiration using a 30G insulin syringe was performed (Figure 1A and B). A magnet and a metal disc were applied on both sides of the auricle and left in situ for 3 days to compress the skin, perichondrium, and cartilage (Figure 1C and D). No hematoma was observed after 1 month, and the crus in the antihelix is clearly seen (Figure 1E).
