Long-term stability of fitting parameters with the COMBI 40

Area of Science:

• Audiology
• Biomedical Engineering
• Otolaryngology

Background:

• The COMBI 40 cochlear implant has been in use for over two years.
• Longitudinal patient fitting data is crucial for understanding device performance over time.

Purpose of the Study:

• To evaluate the long-term development of patient fitting parameters for the COMBI 40 cochlear implant.
• To assess the stability and reliability of fitting parameters for cochlear implant users over a twelve-month period.

Main Methods:

• Analysis of patient fitting data including thresholds and dynamic ranges.
• Data collected at two days, one month, three months, six months, and twelve months post-initial fitting.
• Inclusion of cochlear implant (CI) users from the COMBI 40 European Multicentric Study.

Main Results:

• Patient fitting parameters demonstrated a favorable trend over the twelve-month study period.
• Observed stability in key fitting parameters indicates reliable device performance.
• The safety features integrated into the COMBI 40 were confirmed.

Conclusions:

• The COMBI 40 cochlear implant exhibits stable fitting parameters over the long term.
• Favorable parameter development and integrated safety features provide a foundation for dependable speech understanding.
• The study supports the COMBI 40 as a reliable long-term solution for cochlear implant users.
