In wrestling, judo and mixed martial arts, we can often see people with sharp ears. Commonly known as "Judo Ear" and "Jiaozi Ear". This is caused by local hyperemia of auricle, repeated bleeding without treatment or even repeated stimulation. Below the skin of the auricle is soft tissue and below is cartilage. In wrestling and other sports, it often happens that the ear rubs against the mat, the opponent's clothes and the body, resulting in bleeding between the auricle skin and cartilage. At first, swelling was only caused by congestion, but usually, blood is a transparent liquid that can be absorbed naturally. But repeated stimulation and friction stop bleeding and swelling, blood clots remain, fibrosis gradually occurs, and finally it becomes hard tissue. This happens repeatedly, resulting in the shape of the helix being destroyed. Sometimes it is like a child, so it is commonly known as a child's ear. Relatively speaking, this situation is relatively rare for standing athletes, and there are many wrestlers, including rugby players. However, this does not mean that you have to be the ears of a spoiled child when you are engaged in this sport. According to different people's physique and skills, there are also people whose ears are not congested at all. For example, Yasuya Yamashita's judo player keeps his ears quite well. Once jiaozi's ears are formed, simple treatment is difficult to cure. Because the subcutaneous tissue forms another hard tissue, it must be removed by surgical plastic surgery. In fact, placement will not be a big problem, but it will not look good. There are some white-collar elites who love fighting, so Jiaozi's ears have some negative effects on their image. Also, the auricle helix plays the role of a sound collector, and its deformation has a certain impact on listening. Although it is not serious to daily life, it is always worse than ordinary people. So if you can prevent it, you'd better do it. So, what should we do to prevent Jiaozi's ears? First of all, if the ear is bleeding and swollen, you must protect the wound to avoid being stimulated. It is best to rest, so that basically the congestion can be absorbed naturally. However, this is more difficult for soldiers who can't stop training. At this time, it is necessary to eliminate congestion in time when there is congestion. Try to clear the blood within a week of congestion and swelling. After disinfection, puncture the blood with a fine needle, which is very simple. But even after extrusion, it will continue to be congested due to bleeding. Therefore, it is necessary to use clean cotton wool for proper compression to inhibit bleeding and swelling. And in order to prevent being scratched again, it is best to avoid training sleep skills within 4 or 5 days. Some people will shed their own blood, but it is best to avoid this situation as much as possible. It's a bad thing to infect or leave a wound. If you really want to do it yourself, you should pay attention to cleanliness anyway. My clinic often has athletes to draw blood, including famous athletes such as shooting boxing, taekwondo and wrestling judo. Unfortunately, some doctors don't know how to deal with this kind of injury because they have no experience in this field. There is a mixed martial arts player I like very much. When his ear was bruised and swollen for the first time, it could be finished in one stitch. As a result, a serious doctor carefully opened the knife and stuffed him with cotton wool. Besides, the player didn't go to the hospital again, and as a result, he became suppurated. Fortunately, after I heard about it, I quickly used antibiotics and so on, and it was cured in a few days. But if suppuration spreads to cartilage, it will be very troublesome. It's just an ear, but it's also an ear. Please pay attention to the fighters. Dr. Sun Yat-sen, the author of Diagnostic Manual of Fighting Skills, was born in 1954. After graduating from the Faculty of Medicine of Tsukuba University in Japan, he became a plastic surgeon in Tokyo Police Hospital. Later, he opened the "Zhongshan Clinic". By chance, he became a ring doctor, specializing in this field. He is active in various fighting events such as K- 1, Pride, Kicking Boxing, Karate and Jiu Jitsu. In this book, he introduced a lot of common sense and his experience in the ring, which is very interesting.
