While the auricle consists of elastic fibrocartilage covered with perichondrium and skin, the lobule is made up of skin only. The subcutaneous tissue of the lobule, although highly developed, contains within its meshes only a few vessels and nerves and many fat cells. Thus, on account of its poor vitalization, the restorative power of the lobule is rather weak.
