Hot compress for frostbite of ears can lead to necrosis.
The two ears protrude from both sides of the head, with thin skin and less subcutaneous tissue, and are closely connected with auricle cartilage. Due to the lack of subcutaneous fat protection and superficial blood vessels of auricle, when encountering cold stimulation, vascular contraction is prone to ischemia and hypoxia and auricle frostbite.
No matter the severity of frostbite, don't go to a hot room to keep warm or use hot water bottles, hot towels, etc. Some people have just returned to a warm room from the cold outside, and as soon as they enter the room, they immediately apply hot towels to their ears, which is very easy to cause vasospasm in their ears, and in severe cases, local necrosis will occur. In addition, do not rub hard, otherwise it will easily cause local blood circulation disorder and auricle periostitis.
