Abstract Purpose In recent years, the number of elderly cochlear implant (CI) candidates is continuously rising. In addition to the audiological improvement, other positive effects of CI treatment can also be observed in clinical routine. The “quality of life” as a parameter of success directly experienced by the patient is increasingly becoming the focus of clinical research. Although there are already clear indications of a rapid and significant improvement in quality of life, there is still a lack of systematic, prospectively collected longitudinal long-term data in patients over the age of 65. Methods This prospective longitudinal observational study included 31 patients between the age of 71 and 92 years who had first been treated unilaterally with a CI 6 years ago. In addition to free-field monosyllable recognition, quality of life was assessed using the World Health Organization Quality-of-Life Scale-old (WHOQL-OLD). The results were compared with the data from our previous study, in which we focused on the short- and medium-term effects on quality of life. In both studies, the same patient population was examined. In addition, these study data were compared with an age-matched average population. Results In speech recognition, there was no significant change from the control 6 months postoperatively compared with the results 6 years postoperatively. No significant changes occurred in the total quality of life score or any of the other six facets of quality of life when comparing the results 6 months postoperatively with the results 6 years postoperatively. In “Social participation”, the CI patients even exceed the values of the age-matched average population 6 years after treatment. Conclusion Improvement in the quality of life and especially in social participation appears stable over many years in elderly patients after hearing rehabilitation with a CI.
