Age related aspects of cochlear implantation.

: The objective of this study was to assess the long-term results of cochlear implantation in terms of age-related changes. 67 patients of different age with chronic bilateral severe sensorineural hearing loss and deafness with experience of use of cochlear implants (CI) for at least 5 years were tested. The 1st group included young patients (25,5±7,9 years), the 2nd group - middle-aged (51,4±5,4 years), the 3rd group - elderly patients (67±5,6 years). The examination, which conducted before and after the planned replacement of the speech processor, included: pure tone and speech audiometry in the free field, subjective assessment of satisfaction with CI, assessment of the state of speech function and psychological testing using the Montreal Cognitive Assessment and Mini-Mental State Examination. The increase in speech intelligibility in silence and in a background noise after the replacement of speech processors was revealed. The expediency of cochlear implantation in geriatric practice to maintain the mental and social status of elderly people, prevention of dementia, improving the quality of their lives in the conditions of increasing the age-related risks of sensory and cognitive dysfunction was shown.
