The eyes are the windows to the soul, and the ears are the doors to your perception of the world. However, many people are troubled by the problem of congenital microtia. Let’s talk about this problem today: 1. What is congenital microtia? Congenital microtia, or congenital malformation of the outer and middle ear, is characterized by severe auricular hypoplasia, atresia or stenosis of the external auditory canal, and malformation of the middle ear, while the inner ear is mostly normal in development and has some hearing through bone conduction. It is treated by total ear reconstruction and hearing reconstruction. The prevalence of congenital microtia is high, with statistics in China showing 1:3439. For our large population the number of congenital microtia that occurs is large, affecting their image and quality of life in society. 2. Why do children develop this condition? The exact cause of the onset of congenital microtia is not well understood and may involve various factors such as genetics and pregnancy. However, it cannot be said that it is the father’s or mother’s side of the problem, and there is no evidence to confirm that diet, work and rest, and disease during pregnancy can cause this condition. So parents should not speculate and blame each other. 3. When is the most appropriate time to have ear surgery? The timing of ear reconstruction surgery is important and is one of the main determining factors in obtaining the desired surgical result. We believe that the best age for ear reconstruction is 9, 10 or 11 years old, taking into account the development of the rib cartilage, the development of the earwax and psychological development. If the age is too young, because of its small, thin and soft autologous rib cartilage development, it brings influence to the production of the auricular cartilage scaffold, which affects the final surgical result. Moreover, if the surgery is done too early, more rib cartilage needs to be cut, and the chance and degree of thoracic deformation occurring with one more weight-bearing rib cartilage is higher and heavier than if one less cartilage can be taken at an older age. However, it is best to complete the external ear reconstruction surgery before pubertal development because the psychological changes in children during puberty are significant and completing it before puberty will have much less impact on the child’s psychological development. Although we have solved the technique of ear reconstruction for elderly patients, it is best not to wait until you are too old to have the surgery. As you get older, the texture of the rib cartilage will change and even become yellow and brittle, increasing the difficulty of making the cartilage scaffold for the ear. 4, congenital small ear deformity surgery method “application of autologous rib cartilage staged total auricular reconstruction” is the best surgical way to cure congenital small ear deformity. Method: Using autologous rib cartilage as the ear scaffold, the whole ear is reconstructed in two stages, with the first stage of surgery being the reconstruction of the anatomical structure of the outer ear and the second stage being the reconstruction of the cranial ear angle. In all cases, general anesthesia with tracheal intubation was used, and the surgery was performed in two stages. The first stage involved the reconstruction of the external ear anatomical structure, including rib cartilage excision and ear sculpting and fixation of the ear scaffold, flap excision and ear scaffold embedding in the mastoid area, and transposition and articulation of the ectopic earlobe during the same period; the second stage involved the reconstruction of the cranial ear angle, including lifting of the external ear contour, filling with supporting cartilage or materials, fascial or superficial temporal fascial covering in the mastoid area, occipital The second stage includes lifting of the outer ear, filling with supporting cartilage or material, fascial or superficial temporal fascial covering of the mastoid area, occipital flap advancement and skin grafting; the second stage includes fixation of the ear stent. The interval between the two procedures is 6 months. Advantages: personalized sculpting of the reconstructed ear, realistic shape; good tissue compatibility, able to withstand certain pressure; staged surgery, less traumatic, does not affect normal school life.
