Ear frostbite, also known as auricular frostbite, is a condition in which the skin of the auricle becomes red, swollen, itchy, hot, and always wants to be rubbed with the hand, and gradually feels tingling, sometimes with shiny skin and blisters. In severe cases of auricular frostbite, the skin breaks down and ulcers can occur, and the auricle becomes yellow and crusty. Dry necrosis can occur in the auricle due to long-term ischemia and hypoxia, and it is not uncommon to see “frozen ears”. This can lead to lifelong ear loss and deformity. During the cold winter months, many people suffer from auricular frostbite. The skin of the auricle becomes red and swollen, itchy and hot, and you always want to rub it with your hands, gradually feeling the stinging pain, and sometimes the skin shines and blisters appear. In severe cases of auricular frostbite, the skin breaks down and ulcers can occur, and the auricle becomes yellow and crusty. Dry necrosis can occur in the auricle due to long-term ischemia and hypoxia, and it is not uncommon to see “frozen ears”. This can lead to lifelong ear defects and deformities. Causes: The two ears protrude on both sides of the head, the skin is very thin, the subcutaneous tissue is less, and the auricular cartilage is more closely connected, due to the lack of subcutaneous fat protection, and the auricular vessels are superficial, when encountering cold stimulation, vasoconstriction is prone to ischemia, hypoxia, auricular frostbite. After frostbite, gently massage the auricle with your hand to promote local blood circulation. Regardless of the severity of frostbite, do not immediately go to a hot indoor fire or use hot water bags, hot towels and other sudden heating, so as not to cause vascular spasm, and cause local necrosis. Do not rub the auricle with force, otherwise it will easily cause local blood circulation disorder and auricular pseudocyst and auricular chondromyelitis.
