Cochlear implant is a bionic electronic device that replaces cochlear sensory organs. It can make patients with severe hearing loss hear the sound and make deaf people enter the world of sound from the silent world. Deaf children can avoid hearing loss and enter normal children's schools to learn and communicate. Adults with severe hearing loss can communicate normally through cochlear implants if their hearing AIDS are not properly worn.
2. Is it enough to wear a cochlear implant belt?
No way! Cochlear implants are divided into implanted electrodes and external parts, which require general anesthesia in hospitals. The electrode of cochlear implant can only take effect after it is inserted into the patient's cochlea and connected with its own auditory nerve. Therefore, the patient must have normal heart, lung and liver function and can tolerate general anesthesia before surgery.
3. Do people with poor hearing need cochlear implants?
Cochlear implant surgery is mainly suitable for patients with severe and extremely severe sensorineural deafness in both ears. If one ear is severely or extremely severely sensorineural deafness, and the hearing of the other ear is basically normal, cochlear implant is generally not needed. If one ear is moderately deaf and the other ear is completely deaf, and the effect of wearing a hearing aid is not good, cochlear implant can be considered to improve the patient's speech communication ability. If you have moderate or severe deafness in both ears, you can communicate effectively by wearing hearing AIDS, and you can temporarily not have cochlear implants.
4. When did the infant hearing screening fail to pass cochlear implantation?
Usually, children receive their first hearing screening 3-5 days after birth. If it fails, the child must receive a second hearing screening about 40 days after birth. If it still doesn't work, the child will go to a hospital with children's hearing screening qualifications for hearing screening three months after birth. Usually, a child will receive a comprehensive hearing assessment and a definite diagnosis about six months after birth. If it is indeed severe sensorineural deafness, you can first give your child a hearing aid and observe your child's reaction to sound. If you wear a hearing aid, your child's language development and communication are not good. You can consider cochlear implant surgery at the age of one. If the child is completely deaf in both ears, the operation should be performed as soon as possible from September to 65438+February, and the operation should be performed directly without trying on a hearing aid. Usually, speech training is needed after cochlear implantation, so parents must be patient and gradually cultivate their children's ability to speak and obey. At present, children's ears can also be implanted with cochlear implants at the same time or successively, which is beneficial for children to locate the sound source and obtain more natural sound.
5. Can adults and deaf people do cochlear implants?
Adults or children, if he can speak before deafness, have a hearing and speech foundation, then the effect of cochlear implant is good; Adult deaf-mute people, who have been mute or unable to speak for decades, do not advocate cochlear implant surgery, because such people have poor results after surgery and have difficulty in language learning.
