It is mainly characterized by a downward curling of the upper part of the auricle, covering the triangular fossa, and a reduction in the longitudinal length of the auricle, which is roughly expressed as an enlarged auricle. Some auricles can be restored to their normal shape by pulling upward on the auricle; however, some auricles have cartilage adhesions and cannot be restored to their normal shape even if pulled. Although this type of auricular deformity is not very serious, it is more difficult to correct. The goals of treatment are: 1) to restore the longitudinal length of the auricle; 2) to restore the normal curvature and thickness of the auricle. Our surgery takes an incision behind the ear so that the scar is concealed. The cartilage in the upper part of the auricle is completely removed, and then the cartilage structure is adjusted to restore the shape of the ear wheel, reveal the triangular fossa, and obtain an increase in the longitudinal length of the auricle. The difficulties of the procedure are: 1) preserving the integrity of the skin when stripping the flap from the cartilage surface; 2) fixing the cartilage structure firmly when adjusting it; and 3) ensuring that the skin is tightly bonded to the auricular cartilage after surgery and that no hematoma forms. As long as one of these is not fully implemented, the surgical result will be affected.
