Cochlear implants can help severely or severely deaf people to better communicate with others through hearing, so that they can get more education and employment opportunities, so that they can return to the mainstream society.Although cochlear implants bring new hope to patients with severe and severe deafness, it does not mean that all patients can be implanted with cochlear implants, and they must have a correct understanding and appropriate expectations of cochlear implants.
We must know that cochlear implants bring joy in life to many deaf people, but also understand its limitations:
First, the implanted cochlear implant cannot repair the damaged hearing system.Damaged auditory nerve fibers cannot be repaired or replaced in medicine.If only a few auditory nerve fibers remain, they will not be able to transmit enough information to the brain to understand complex sounds like language.Secondly, although cochlear implants are helpful to deaf people, they are not perfect, and they are far from reaching the hearing ability of normal people. We must have a full understanding of this.Therefore, when deaf patients consider cochlear implants, they must first determine whether they are qualified candidates for cochlear implants.
Not all patients with severe deafness or those who are ineffective in wearing hearing aids are suitable for cochlear implantation. The factors that affect the effect of the implantation are: the length of the deafness, the age of the deafness, the cause of the deafness, the condition of the inner ear nerve fiber, The imaging of the inner ear and so on.In addition, many factors such as the patient’s desire to regain hearing and family financial support may affect the effect of cochlear implantation.
不同的选择标准是：成年人必须是语后聋患者且鼓岬电刺激阳性，但无明确年龄限制，青年人、中年人以及老年人，只要是语后聋且符合手术麻醉要求，都可以植入；对于小儿患者，最小者年龄在12个月(美国FDA通过)即可行该项手术，在一些特殊情况下，植入手术的年龄还可以再提早数月。语前聋的患者于8岁前进行手术效果较好，尤其4岁前效果尤佳；若术前患者能佩戴3－6个月 Hearing aid ，并进行听力康复训练，将对术后言语能力的提高有很大帮助。
To implant a cochlear implant, a complete hearing rehabilitation education plan is required, and parents also need sufficient financial and material resources.In addition, children should exclude some diseases that are not suitable for surgery, such as incomplete or missing bilateral auditory nerves, nerve damage that causes auditory nerve blockade, significantly lower intelligence, and the risk of implantation exceeds the benefit.
In addition, there are some factors that affect the choice of patients. For example, patients with degenerative neurological diseases and cerebrovascular diseases are not suitable for cochlear implantation.Cochlear implant surgery also has certain risks, such as facial paralysis.In short, cochlear implantation also has requirements and selection criteria for patients. Don’t think that patients who are extremely deaf and who wear hearing aids are ineffective can choose cochlear implants.
