Die Cochlea-Implantationen bei Erwachsenen

The study is an overview of results of all 46 adult patients (mean age 40.1 y., range 19 to 67 y.) implanted in the years 2000-2004 in our implant center with both Cochlear Implant (CI) and Brainstem Implant System (ABI) by Cochlear. In the CI group 5 patients were older than 60 years. There are results structured in correlation of patient's age in time of implantation, aetiology of hearing loss, pre-operative electrical stimulation, pre-operative hearing loss duration, pre-operative residual speech perception with hearing aids, lip-reading ability, minimal auditory capabilities. Post-operatively - number of inserted electrodes and the way of rehabilitation is mentioned. Post-operative successfulness is evaluated by means of objective audiological tests of speech perception (open-set and closed-set word identification tests in free field), pure tone audiometry, using the telephone ability, subjective quality of life assessment and there is a short summarisation in Nottingham scale too. The study is specially concentrated on long-time progressive hearing loss effectiveness of implantation and age-related post-operative performance as a contribution to predictors of cochlear implant performance detection
