Complications that may be caused by ear holes, unqualified disinfection may lead to infectious diseases: if not strictly disinfected, hepatitis, sexually transmitted diseases and even AIDS can be transmitted through ear holes, and serious infection may lead to the absorption of ear cartilage and deformation of the whole auricle. If you disinfect by giving the operator some conscience and basic medical knowledge, then there is one more thing you have to do, and that is keloids in your ears. Keloid, also known as keloid, grows like a tumor and occurs in some special parts of the body, such as earlobe, sternum and acromion.
