What's the difference between a cochlea and a hearing aid? 1. There are differences between the two groups. Cochlear implants are more common in people with severe and extremely severe prelingual hearing loss.
2. The intervention methods of the two are different. Hearing AIDS are second-class medical devices, which use the residual hearing of the hearing impaired without trauma; Cochlear implants need surgical implantation, and hearing can be produced by electrical stimulation, not human ears. Cochlear implant has certain risks.
3. From the perspective of hearing compensation effect, the high-frequency sound compensation of cochlear implant is better than that of hearing aid, and the low-frequency compensation effect of hearing aid is better than that of cochlear implant. At present, the intervention methods of hearing aid unilateral cochlear implantation are mostly used for people with severe or above bilateral hearing loss.
Cochlea and hearing AIDS are better. Hearing AIDS and cochlear implants are better. This problem depends on the specific situation of hearing loss. If the degree of hearing loss is less than 90 decibels, the effect of intervention and rehabilitation after wearing hearing AIDS is ok, then wearing hearing AIDS can also meet the hearing needs. When the hearing loss exceeds 90 decibels and the hearing aid effect is not good, the best hearing intervention method is cochlear implant. For infants and young children, when ABR or ASSR is extremely severe, hearing AIDS should be worn for three months before cochlear implant intervention to help children learn to speak, otherwise they will become deaf.
Is there sequela after cochlear implantation? For children, formal speech rehabilitation training is needed after cochlear implantation. Generally speaking, the younger the implant, the more timely the speech rehabilitation training and the better the rehabilitation effect. From the indications, for older children and adults, retrolingual deafness is one of the prerequisites for cochlear implantation, so patients with retrolingual deafness can completely implant cochlear implants. Clinically, many patients with retrolingual deafness have achieved good rehabilitation effects after adaptation and debugging.
