Cochlear implant is used to stimulate the auditory nerve to make the patient feel the sound. It is mainly suitable for severe or extremely severe cochlea in both ears.Hearing loss, Does not apply to posterior cochlear hearing loss.In addition, some contraindications should be excluded.
Patient’s age requirement
According to whether the patient has learned language, it can be divided into pre-lingual deafness and post-lingual deafness. The optimal implantation age for patients with pre-lingual deafness is 12 months to 6 years, because the human hearing and speech centers need sound stimulation to develop normally, 6 After years of age, it has been basically fully developed.Postlingual deaf patients can be implanted at all ages.
WornHearing aid, But no obvious effect
Although cochlear implants are very expensive, it is not the most expensive or the best. As long as hearing aids are effective, cochlear implants are not considered. http://www.jhhearingaids.com
Surgical contraindications
1) Severe deformity of the inner ear.The inner ear is so badly deformed that it is impossible to place cochlear implant electrodes.
2) Defect of auditory nerve.The auditory nerve is dysplastic or undeveloped.
3) Fracture of the cochlea.Cochlear fractures may damage the vestibular nerve of the cochlea, rendering cochlear implants ineffective.
4) Cochlear implants are not considered for other surgical contraindications.
Correct understanding and expectations
Family members and myself should have correct understanding and expectations of cochlear implants. Most patients with cochlear implants around the age of 1 have good results and can receive education normally, but pre-linguistic deaf patients older than 7 years old even if they have cochlear implants, they may hear sounds but do not understand the language.
Hearing rehabilitation
After cochlear implantation, hearing and speech training are required in professional rehabilitation institutions.
