Ear piercing is bound to have a wound, which can easily lead to infection. Doctors usually use antibiotics, but the external ear is mainly composed of cartilage. In the whole head organ, the blood circulation of the external ear is the least, so it is difficult to get effective treatment with antibiotics. The blood circulation of the soft tissue in the upper ear is much worse than that of the earlobe, so the probability of bacterial infection after puncture is much greater than that of the earlobe. The so-called "painless ear piercing" on the street is not necessarily safe. Some stall owners put earrings on the gun head before drilling holes, even without alcohol disinfection, aiming at the position to directly hit the auricle. More importantly, drilling holes without holes in the ear will not only make it easy for bacteria and viruses to invade, but also cause chondritis and atrophy of the ear. Once the ear infection expands, develops into suppurative periostitis and even leads to auricle necrosis, it must rely on surgery. In fact, the upper ear hole hurts much more than the earlobe hole. If you have to pierce the upper part of your ear, you should fully consider the risk of doing so. Experts remind that after ear piercing, you must pay attention to keeping the perforated part clean; In addition, it is best to apply anti-inflammatory drugs every day before the ear hole is punctured and the wound has not healed, so as to reduce the chance of infection. Strictly speaking, ear piercing is a minor operation. Regular hospitals will sterilize the instruments used for ear piercing, and the earrings used for ear piercing should be sterilized by high pressure. Therefore, people who really want to get their ears pierced must go to a regular hospital. Finally, we should warn those friends who blindly pursue fashion that a lot of ear holes are not necessarily beautiful, but a healthy image is the most beautiful.
