There are several treatments. Some take costal cartilage and put it on the ear for a long time. Usually, a dilator is buried to expand the skin, and then costal cartilage is implanted behind the ear. This method generally does not have rejection, because your cartilage is implanted under the original skin.
There is also an artificial stent, that is, an artificial auricle, which will have a certain rejection rate.
The cost is about 30 thousand to 50 thousand yuan. At present, this disease is relatively common, which is generally caused by drug abuse. Don't worry too much, and there will be no inheritance in the future. Don't make suggestions that don't affect your appearance, just pay more attention to the cultivation of your child's character.
