Summary :
Objectives: To study and compare the evolving capacities of speech discrimination with cochlear implants in older patients compared to patients implanted at a younger age. Methodology: A retrospective study comparing a group of 52 patients aged over 65 with a control group of 58 patients aged between 30 and 50 years, followed for 5 years after implantation. We analyzed and compared the evolution of speech discrimination in silence (disyllabic words, sentences) and noise (sentences, S/N ratio: +10 dB) after implantation. Results: In the group of elderly patients, the speech discrimination in silence remains stable over time (for disyllabic words, score at 6 months: 72.8 ± 20.2%; score at 5 years: 73.7% ± 19.7). Discrimination in noise tends to improve (mean score at 6 months: 70.5% ± 21.5; score at 5 years: 76.9% ± 16.9). The results obtained are in silence are comparable to the results of the group of patients aged between 30 and 50. In noise, their performance remains lower than the control group (mean differences between scores: -10.8; confidence interval at 95%: -17.9, -5.3). Conclusion: The cochlear implant is effective over the long term in elderly patients, for speech discrimination in quiet and in noise. In silence, their performance is comparable to younger patients with implants.
