a less distinguished posterior relief. With the exception of the cartilage-free lobule, the static basis of the auricle is formed by an elastic cartilage, which has a thickness of 1 to 3 mm. 1,2,3 The anterior skin is fixed to the perichondrium without subcutaneous tissue in between, being almost immobile. It is 0.8 to 1.2 mm thick. In contrast, the posterior side has a subcutaneous layer of 1.2 to 3 mm, which leads to a certain mobility. 3 The blood supply of the auricle is variable and dominated by branches of the superficial temporal and posterior auricular vessels. Innervation of the auricle is due to branches of N. auricularis magnus, N. auriculotemporalis, and N. occipitalis minor. The auricular muscles are relatively unimportant and small. Two muscles might be detected intraoperatively: M. auricularis posterior and M. auricularis superior. In addition, the auricle is stabilized by one posterior and two anterior ligaments. 1 The lymphatic fluid of the auricle is drained into the superficial and deep neck nodes, into the parotid gland, and toward the submandibular nodes and, in addition, the postauricular and mastoid lymph nodes.
