Children wearing non-invasive orthotics
The other is abnormal auricle structure. Abnormal auricle structure is the hypoplasia of skin or cartilage caused by abnormal embryonic development, that is, microtia, which we usually call microtia, is an accidental event caused by congenital dysplasia. The world incidence rate is reported as 1/5000- 10000. At present, the etiology is still inconclusive, which may be related to pregnancy infection and exposure to teratogenic substances. Different forms of microtia
Children begin to pay attention to their deformed auricles at the age of 3 to 3 and a half. I will compare the difference of my ears in the mirror and start to mention my "small ears". When children pay attention to their small ears, parents should tell them that they are born with small ears. When they grow up, the doctor will let their little ears "grow up" and treat them as completely normal children. Parents pay too much attention to deformed ears, which will make children have psychological burden and inferiority complex prematurely.
70%-90% of children have unilateral microtia, and the opposite ear can hear the sound normally, so it rarely affects the speech development of patients. Bilateral microtia will seriously affect children's speech development and cause obvious communication obstacles. These patients need to wear bone conduction hearing AIDS as soon as possible to restore hearing. At present, the commonly used soft bone conduction hearing AIDS have a good effect on conductive deafness in children, and families with conditions should use them as soon as possible.
At present, microtia, whether hearing loss or auricle deformity, can be treated and recovered by various methods. Considering both psychologically and physically, the ideal age for auricle reconstruction surgery is before children enter school. Generally speaking, it is not recommended to operate on microtia before the age of 6, because it is not until the age of 6 that the child's ribs can be carved and made into auricle brackets, which can better cooperate with postoperative care. The commonly used and simple criteria for judging whether surgery can be performed in clinic are: height 1.2 or above, and chest circumference passing through xiphoid plane 55cm or above.
Total auricle reconstruction is a challenging task, which needs to be completed several times. The doctor took out part of the costal cartilage of the patient's chest, carved it into the shape of a solid auricle cartilage bracket, and then placed it under the skin "pocket" of the affected side. After that, the newly built auricle will be erected to make it more three-dimensional. The auricle made of costal cartilage is "alive", so it can grow with growth. Compared with artificial materials, it has good histocompatibility and strong compression and damage resistance. Ear cartilage scaffold carved by autogenous costal cartilage during operation and its postoperative manifestations
For the hearing problems of patients with microtia, many years of clinical experience shows that if the child's ear canal is completely undeveloped, it is manifested as atresia of the ear canal. If the doctor opens the ear canal through surgery, the long-term hearing effect after surgery is not ideal, and the artificially opened ear canal needs lifelong care. In this case, it can be considered to install bone conduction hearing AIDS or implant vibrating bridges to improve hearing; If the child's ear canal is narrow and there is a risk of cholesteatoma in the external auditory canal, it is recommended to perform ear canal plasty and tympanoplasty to obtain a healthy ear canal and good hearing. If external auditory canal secretion or odor is found, it is recommended to see an otolaryngologist as soon as possible.
