Some babies after birth found that one or both sides of the ear and normal people are not quite the same, this is because of a disease called microtia, so this situation when we should face it? Microtia, or known as congenital malformation of the outer and middle ear, manifested as auricular hypoplasia, atresia or narrowing of the external auditory canal, malformation of the middle ear, while the inner ear development is mostly normal, through bone conduction with a certain degree of hearing. Microtia is a congenital malformation of the auricle, and the severity of the malformation can vary greatly. The most severe malformations are characterized by the absence of an ear or a small amount of residual ear, while the mildest show an approximation of the auricle, but are significantly smaller than normal. The prevalence of congenital microtia varies in the literature, depending on ethnicity and geographic location. The most recently reported incidence in China is 5.18 per 10,000 births, which means that on average, one case of microtia occurs in every 2,000 births. Causes The causes of microtia are still unclear, and are generally believed to be the result of a combination of environmental and genetic factors. Environmental factors such as viral colds during the mother’s early pregnancy, overreaction to pregnancy, and toxic substances in home furnishings are all factors that may lead to the onset of microtia, and the incidence of genetic predisposition in patients with a family history of microtia is roughly 2.9%-33.8%. How is it treated? Microtia is mainly treated with surgery, which is chosen when the patient is 5-6 years old, i.e. pre-school age. Surgery is very complicated, most of the surgery needs to be staged in order to be completed, the specific surgical methods include the following: 1, direct burial method, currently used especially, but also a more advanced surgery, this surgery is the first time to bury the ear, the second time is to stand up the ear, and the third time is to repair and reconstruct the ear, which requires three times to complete the surgery. 3, skin expansion method, skin expansion surgery is divided into two main types, one is a half-wrap method, a full-wrap method, the two surgeries are generally the same, but each has its own advantages and disadvantages. The whole package method is the first time in the mastoid region of the residual ear buried water capsule, 7 days after the operation began to inject saline. The injection of water is started 2-3 times a week, and the injection takes about 3 months, the injection volume is 120ml or more, and then recuperate for about 1 month. The expander is taken out for the second time, then the patient’s own rib cartilage is taken and the ear brace is sculpted according to the size of the opposite ear for the ear reconstruction, which requires about 7 days of hospitalization after the surgery. Ear reconstruction surgery for microtia is not a very difficult surgery under today’s medical development, and the reconstructed ear after surgery can be almost the same as the normal ear under non-close observation. The most important thing is the mentality of the parents and the child, and it is also very important to choose an experienced doctor and a regular hospital.
