Have you ever paid attention to the different forms of ears? They are like a pair of sentinels, always on guard on both sides of our body, alert to all kinds of sound information, judging the location of the source of sound. At the same time, as one of the five senses, they shyly hide among the hair traces on both sides, giving their exposure selflessly to other brothers, making it difficult for us to recall their existence, or even their appearance; we hardly have the chance to observe the morphological details and characteristics of both ears at the same time. So now, let’s pay attention to our faithful friends, to the ears in their various forms. The ear, as the hearing organ of the human body, can be divided into two major parts, the outer ear and the inner ear, in terms of anatomical relationships and tissue origin. Usually we do not have the opportunity to see the inner ear because of its delicate and soft structure, which the body hides inside the tympanic chamber of our skull, separating the outer ear from the inner ear through the tympanic membrane. What we usually see is actually the outer ear that we are going to introduce to you today. With the process of biological evolution, different species of organisms have evolved very different ears due to their adaptation to the requirements of nature, and we can even identify the genus of a species by the difference in the shape of its ears, such as the largest family of bats, which is distinguished by the shape of its ears. The same is true for us humans, there are almost no people with identical ears, so much so that there is a so-called ear statue in China since ancient times. Nowadays, with the development of personalized clothing and hairstyles, earrings have never been more important and developed. So have you ever imagined what would happen if there were no ears? In fact, just like all our other organs and tissues, from the beginning of human existence, congenital and acquired diseases have followed each other. There are many unfortunate friends who are born with one or even both ears (outer ear) that are not developed or developed abnormally. These abnormalities are referred to as “wind-up ears”, “cauliflower ears”, “hidden ears”, “ape ears”, “attached ears” and “microtia”. The most serious and painful of these is microtia, which is a complete abnormality of the auricle. Because the causes and early screening methods for this disease have not been completely resolved, it is extremely difficult to prevent it, and its incidence has been increasing year by year in recent years. As mentioned earlier, due to the specific location of the ear and the intentional concealment of the patient, we may rarely observe the ear deformity in our lives. Despite this, we can still put ourselves in the shoes of the families of these patients and the pain they feel in their hearts, is there no solution? Of course not. With the rapid development of plastic surgery in recent times, the dream of reconstructing an ear is not so far away. As early as the 19th century, attempts were made to repair auricular deformities using allogeneic materials, and later scholars repeatedly tried to use allogeneic and autologous tissues to repair the shape of the ear, before gradually realizing that sculpted scaffolds of autologous rib cartilage were the most ideal material for repair. With the introduction of the expansion technique, it has brought a boon to our Mongolian Asian race in particular, solving the problem of insufficient skin area behind our ears, which is prone to scar formation, and allowing the formation of a natural and adequate cranial angle of the ear, satisfying the traditional Chinese idea that large ears are blessed. This is why the expansion method with autologous rib cartilage stent placement has become the most suitable treatment method for the Chinese people. What about the timing of the surgery? With the development of modern society, people are paying more and more attention to the issue of mental health. In order for children with deformities to have a healthy psyche, the current time of surgery is advocated to be between 6-8 years old before school. Also, since the growth of the ear is concentrated between the ages of 8 and 10, the child’s ear will be close to the size of an adult by this time and will not have a significant impact on future growth. If you have a friend in need of help, please lend a helping hand; let’s start now to care about our ears and help those who are suffering from auricular deformity, so that we can welcome a better tomorrow together.
