Introduction: The so-called "wind ear" refers to the ear with excessive included angle between the auricle and the lateral wall of the skull, showing transverse process deformity. We call this kind of transverse process deformity of external ear "wind ear", also called flat ear. The method of pulling ear correction takes a long time compared with complicated surgery, which usually takes 2-3 hours. According to experts, the common ear flap plastic methods mainly include suture method and cartilage tube method. Suture is mainly aimed at some people whose condition is not very serious, while cartilage tube method is suitable for all cases of congenital earlobe that is too big, too small, too long, too pointed and earlobe cracked, and some acquired earlobe defects can also be improved by surgery. However, it should be noted that if you belong to scar constitution, it will affect the avoidance of earlobe surgery. Before the operation, you should design the shape of your ears according to your face, and then do it under anesthesia. The most commonly used method is that the surgeon makes a small incision behind the ear to expose the ear cartilage. Then carve the cartilage and bend it backwards, close to the skull. Nowadays, absorbable sutures are widely used to keep the shape of ears. Sometimes, doctors need to remove a piece of cartilage so that the wrinkles in the ears look more natural after surgery. In addition, another technique is to make a similar incision behind the ear. Cut off part of the skin and fix the ear cartilage with suture to keep it folded without cutting the cartilage. The plastic surgery of ear flaps was initiated by Dr. Dai Ba Fenchi on 1845. After numerous innovations and transformations by doctors, it is now very mature, and there are many surgical methods, but the general surgical principle is nothing more than: 1, removing excess skin behind the ear; 2. Reconstruct the normal auricle shape by bending the abnormal lateral auricle cartilage; 3, suture the skin behind the ear, pressure dressing. Dressing was changed three days after operation, and stitches were removed on the seventh day. As long as the method is correct, ear correction surgery is generally effective. Plastic surgery usually takes 2-3 hours, and more complicated surgery takes a long time. The technology used depends on the conditions. Most patients left an inconspicuous scar behind their ears after operation, which gradually subsided with time. Even if one ear protrudes, both ears are often operated to achieve a better balance.
