MED-EL Cochlear Implants (CI) provide auditory sensations via electrical stimulation of the auditory pathways for severely to profoundly hearing-impaired individuals who obtain little or no benefit from acoustic amplification in the best aided condition.
However, there is only few evidence from large long-term observational studies available to gain knowledge on clinical effectiveness of cochlear implants. With continued pressure on healthcare system budgets, there is an increasing demand for evidence-based research that demonstrates an intervention is effective in the real-world environment across large and diverse populations. Currently, there is a paucity of data concerning the long-term outcomes of subjects implanted with a SONATA 2 cochlear implant from representative samples of the population. This retrospective study aims at analyzing SONATA 2 cochlear implant data from clinical routine.
At least one MED-EL SONATA 2 cochlear implant with a compatible MED-EL audio processor
Lack of compliance with any inclusion criteria
In this retrospective observational study, the inclusion and exclusion criteria encompass all individuals with a SONATA 2 cochlear implant at the study centers. By including all individuals with a SONATA 2 cochlear implant from the study centers, the investigation population is representative of the target population. The investigation population is representative of "real-world" users of SONATA 2 cochlear implant.
