When piercing the ear bone, it is generally not recommended to pierce other parts of the ear except for the location of the earlobe. The main reasons are as follows: First, other parts of the ear generally have the presence of cartilage, and after piercing the ear to the cartilage, the patient will have more obvious pain and may bleed more. Secondly, if the patient is a keloid, when piercing the ears and hitting the cartilage, it will easily lead to cartilage hyperplasia and the formation of keloids. Once the keloids are formed, it may be clinically necessary to perform a second surgery to remove them, otherwise they will grow bigger and bigger. Thirdly, if the ear piercing is done to the cartilage, it is easy to induce cartilage infection. Once the cartilage is infected, it is very difficult to control, and it is easy to form purulent auricular chondromyelitis, which leads to repeated local infection, pus, cartilage necrosis and even deformity of the auricle and other related changes. It is recommended that patients go to a regular hospital or a sterile and clean environment to have their ears pierced by an experienced doctor, and not to go to unclean and unhygienic places such as the roadside to have their ears pierced.
