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.
