Cochlear implantation – diagnosis, indications, and auditory rehabilitation results

Early and reliable diagnosis is crucial for the successful rehabilitation of profound hearing disorders. For children, the (obligatory) newborn hearing screening plays a key role, so that a CI (cochlear implantation) fitting should take place within the first year of life. 86% of children fitted with a CI achieve speech comprehension for common sentences.

In adults, the motivation of the affected persons to avoid the occurrence of hearing loss after language acquisition (postlingual) and a short duration of deafness are favorable prognostic factors. The hearing rehabilitation particularly for elderly patients is not only associated with a significant improvement in hearing and speech comprehension, but also with a significant increase in quality of life. In the case of bilateral hearing loss, bilateral CI treatment should be the preferred option regardless of age.

Technical implant defects, dizziness and wound healing disorders are the most common causes of hearing loss, ranging from 2-4 complications of the intervention.

Conclusion: Cochlear implantation is a safe and reliable procedure in specialized centers and regularly enables successful hearing rehabilitation in children and adults.
