Reabilitation of patients in cochlear implantation

Aim. This study aims to compare the major role is played by the following objective fitting methods for such CI-users: registration of electrically evoked compound action potentials (eCAP), electrically evoked stapedial reflexes (eSRT), electrically evoked auditory brain stem responses (eABR). Materials and methods. This study includes 100 patients after CI-users, aged between from 12 and to 55 years old. Participants primarily patients were initially fitted in accordance with subjective maximum comfortable loudness (MCL) levels. Results. Results show that the correlation between in eSRT and MCL levels was accounts to 0.87. Correlation between eCAP and MCL was accounts to 0.52. To evaluate the MCL thresholds with eABR, we used 3-5 supraliminal stimuli were applied on 2, 5, and 10 electrodes, respectively. The correlation between the subjective MCL levels and the calculated MCL levels was 0.86. Conclusion. As can be seen from the above, there has been a with the significant increase of fitting objective methods accuracy in the audiological performance of CI-users patients after following the application of cochlear implantation notably improve objective fitting methods.
