Clinical trials

In this study, the performance with the CI is investigated over time in three groups of freshly implanted CI users. Both the standard frequency-band distribution and anatomy-based fitting will be used to compare outcomes.

Aims: To evaluate the perception and enjoyment of music in cochlear implant (CI) users using specific questionnaires, and comparing their results with a control group of subjects with normal hearing (NH). To analyze the musical abilities of implantees using the musical tool Meludia, and compare the results with the control group. To perfom a voice analysis in implanted patients, compare it with their NH peers, and check if an association with musical perception is observed. Design: Cross-sectional study, both the CI recipients and NH control subjects were assessed once. Setting and subjects: Pre-or perilingual patients aged 6 to 17 years old, and postlingual adults who underwent cochlear implantation from 2000 to January 2023 at La Paz University Hospital. Control group is set up with their NH peers. Study Variables: Socio-demographic and clinical (current age, age at implantation, sex, educational level) variables will be collected, as well as hearing loss (aetiology, duration of deafness), and surgical (type of implant, complete or partial insertion of the electrodes, date of surgery) data. Data from CI fitting (number of active electrodes, type of audio processor) and hearing outcomes with the CI will also be reviewed. Outcome variables: Specific musical skills questionnaires for adults: Munich Music Questionnaire (MuMu) and Music Related Quality of Life Questionnaire (MuRQoL), which will be validated. Musical questionnaire developed specifically for subjects between 6-17 years old. Musical tool (Meludia) to assess musical perception. Praat software for voice analysis. Analysis of the impact of the different audiological, sociodemographic and clinical variables on hearing outcomes, and on musical perception after cochlear implantation, and comparison with the NH control group.
