Objective: To conduct a systematic review of the effectiveness of early digital cochlear implantation compared to late implantation on speech recognition in young adults with severe or profound hearing loss. Methods: The studies addressed were a longitudinal comparative study with a control group, retrospective study, long-term follow-up longitudinal observational study, methodological study of psychometric development and validation, prospective cohort study with longitudinal follow-up, prospective longitudinal cohort study, retrospective single-center cohort study, cross-sectional observational study, prospective observational study, descriptive observational study with genetic analysis, and systematic review. Results: The search found 72 articles were reviewed and 15 were selected based on the inclusion criteria established using the PICO method. The findings demonstrate that early cochlear implant placement is associated with greater success in speech recognition and better auditory adaptation compared to those who receive the implant at later stages. Conclusions: These results emphasize the importance of performing interventions at the right time to improve outcomes.
