The auricle is a left-right symmetrical tissue structure located on both sides of the skull that is associated with sound collection, and to a large extent also affects the cosmetic and mental appearance of the human body. Changes in the integrity and morphology of the auricle due to various causes can be psychologically distressing. The more common redundant lesions of the auricle include hemangiomas, lymphangiomas, papillomas, benign melanomas, and seborrheic keratoses, most of which require surgical excision and implant repair. Most of the upper part of the auricle is scaffolded by elastic cartilage and covered with skin with little subcutaneous tissue, and its small post-surgical skin defects are well suited for repair with skin grafts. A skin graft is a piece of skin that does not contain subcutaneous fat tissue. The area of the skin donor is called the donor area and the area of the skin recipient is called the recipient area. Clinically, the skin graft for small defects in the auricular skin is usually the superficial skin graft (also known as a blade-thick skin graft) of the posterior mastoid region of the ear, which is the thinnest skin graft including the epidermal layer and a very small amount of the dermal papillary layer. Its advantage is that it is highly viable and can survive for long periods of time on oozing plasma, and is therefore easily viable. With the judicious use of this dermal sheet, the removal of many ear flaps becomes easy, quick and efficient.
