After the auricle of cauliflower ear is squeezed or twisted, hematoma is formed under the eardrum due to oozing blood, which leads to ischemic necrosis of auricular cartilage. The necrotic tissue is gradually organized into connective tissue, and the fibrous connective tissue is easy to contract, which makes the auricle gradually thicken and shrink. There are many irregular protrusions on the surface, and there are shrinkage gaps with different shades between the protrusions, which are similar to cauliflower, so it is called cauliflower ear malformation. Plastic treatment of cauliflower ear deformity should be carried out after the inflammation has completely subsided and the condition is stable. Cauliflower ear surgery is a very difficult plastic surgery, which usually requires multiple operations to complete, and the final effect is not ideal. There are almost no perfect repair results in clinic. Therefore, it is very important to prevent ear infection and early active treatment after auricle is squeezed or injured. Deafness is a congenital ear malformation, which is characterized by the upper part of auricle cartilage hidden in the temporal scalp, and the ear connected with the scalp in the front of auricle is located in the same plane, and there is no posterior auricular groove separated from the cranial side. In addition, deafness is often accompanied by other deformities. Because there is no posterior auricular sulcus, deafness brings great inconvenience to patients. In addition to not wearing eyes when taking a bath, water can easily flow into the external auditory canal. It brings a lot of inconvenience to patients' lives and should be treated as soon as possible. /kloc-infants under 0/year old can be treated by non-surgery, that is, by massaging the shape of the upper part of the auricle of the child, and then fixing it on the upper part of the auricle to keep it in a state of continuous traction, at which time the tense skin gradually relaxes and reveals the shape of the auricle. /kloc-surgery is required after 0/year old. Adults who need correction can generally have surgery. Children need general anesthesia surgery, and bilateral deafness can be completed in one operation; Adults can do it under local anesthesia. The surgical method is to dissect the upper part of the auricular cartilage hidden in the temporal scalp and establish a stable posterior auricular sulcus. Specific methods can be divided into skin grafting and local skin flap approval. The operation method is simple and the effect is stable. Therefore, surgery can not only improve the appearance, but also solve the dysfunction. In eastern countries, earlobe is taboo for westerners, but it is still regarded by some as a symbol of success, happiness and wealth. What's more, they are regarded as a sign of children's intelligence. So although ear flaps are very common in China, few people ask for treatment. However, in western countries, the situation is completely different. Children with ears are considered unlucky or not smart. On the contrary, it often becomes the object of ridicule by peers, and the constant nicknames such as "donkey ears" and "rabbit ears" cause psychological and spiritual pressure on children. Auricularia auricula is a common congenital auricle malformation, which is generally believed to be caused by incomplete helix formation or hypoplasia of concha cartilage in embryo. These two malformations may exist separately or simultaneously. Ears are bilateral and common, but the deformities on both sides are different. The same deformity can usually be found in his parents' brothers and sisters. Indications of ear flap plastic surgery: Ear flap plastic surgery is minimally invasive and generally acceptable for patients who want to improve the shape of auricle. In order not to affect the normal psychological development of children, surgery can generally be performed at the age of 5-6. At this time, the auricle is only a few millimeters away from the adult, and the operation has little effect on its development. Bilateral auricle plastic surgery should be completed in one operation. Contraindications of ear flap plastic surgery: patients with acute and chronic otitis media should have middle ear surgery first, and those with scar hyperplasia should not have surgery. Postoperative treatment and precautions: antibiotics are generally used for 3-5 days, and the dressing is opened and the stitches are removed about 10 days after operation. Avoid irritating foods such as ginger, raw onions, raw garlic, peppers and seafood. Pressing and hitting the ear should be avoided in the near future after operation to avoid suture breakage. Cup-shaped ear Cup-shaped ear is a congenital malformation between wind ear and small ear, accounting for about 10% of all kinds of congenital ear malformations. Bilateral is common, but the left and right sides are not necessarily symmetrical, and there is a certain heredity. Cup-shaped ears have four main characteristics: the auricle is curled, but the helix is folded by itself, and the whole auricle droops to cover the ear hole. The auricle leans forward, that is, the ear of the wind, but it is different from the deformity of the ear of the wind. The auricle becomes smaller, mainly because the length of the auricle becomes shorter. The position of auricle is low, which is more obvious in severe cases, and is often accompanied by maxillofacial deformity. Cup-shaped ears are also often called curled ears, drooping ears and so on. Because it looks like a rope has been put on the edge of the spiral to tighten it. Therefore, some people call it a shrink ring ear. Make an incision on the back inner surface of the auricle parallel to the upper edge of the helix, and the edge of the helix is at least 1cm to expose the curled and deformed cartilage; Then it is lifted in an arc shape, properly placed on the posterior medial surface of cartilage at the position of ossicles, and several stitches are fixed by intermittent suture with thin lines. If the spiral formed is not obviously curled, it can be curled by scratch method. If the ear is not beautiful or complete, our hospital will choose plastic surgery to repair or improve the appearance. Beautiful ears seem to open a skylight for young people who are unconventional, but they can't look up at the skylight, but they are more eager for beauty and personality.
