Opinions on cochlear implant use in senior MED-EL patients.

This study assessed the subjective benefits of cochlear implants in senior patients wearing a MED-EL device. Data was compared with previous studies to assess the influence of recent speech-coding strategies and behind-the-ear speech processors; users of the behind-the-ear device and the body-worn device were also compared. An adaptation of the Nucleus 22-channel survey was sent to 141 cochlear implant users. The survey assesses perception of the device, communication benefits, handling the device and quality of life. Ninety-five surveys were returned. Results demonstrate that advanced technology provides greater benefit now than 9-13 years ago, notably: improved listening across noise, better understanding on the telephone and better speech perception. Users of the behind-the-ear device did not report more difficulties than body-worn device users but demonstrated better performance. Results show a positive outcome for cochlear implantation in a MED-EL seniors group.

Long-term data on children implanted with a short electrode array.

Ossification and cochlear malformations are no longer seen as a contra-indication to cochlear implantation. The MED-EL COMBI 40+ short electrode was designed specifically for cases where major ossification has occurred, or where full insertion of an electrode may not be possible due to abnormal structure of the cochlea. This study investigates outcomes of 18 children implanted with the short electrode array. These children were assessed using the EARS test battery pre-operatively and at a number of intervals thereafter. Results show a consistent improvement in time on most tests; these results appear to be independent of aetiology. Data from these children were compared to 18 matched pairs implanted with the standard COMBI 40+ electrode array. The short electrode children do not perform as well as the standard children initially, but do tend to catch-up at later test intervals. Results indicate the benefit of using a short electrode when complete insertion of the standard electrode is not viable.
