Cryptotia, also known as buried ear or pouch ear, is a congenital developmental malformation of the auricle. The main manifestations: The upper part of the auricle is buried under the skin of the temporal scalp, and there is no obvious postauricular groove. In mild cases, only the upper part of the auricle is short of skin, and the development of ear cartilage is basically unaffected; in severe cases, in addition to the severe shortage of skin, the cartilage in the upper part of the auricle is also obviously stunted. In severe cases, in addition to a severe shortage of skin, the cartilage in the upper part of the auricle is also significantly underdeveloped. Treatment principles: The skin of the upper part of the auricle is incised so that the buried auricular cartilage is fully exposed, and the wound can be repaired by skin grafting or local flap transfer. Postoperative antibiotics are routinely applied for 3 days, and stitches are removed 1 week after surgery for local flap transfer and 12-14 days after surgery for skin grafting.
