Summary
Unilateral cochlear implant (CI) recipients report significant, stable hearing improvements long-term. Pre-implantation factors like hearing aid use and age influence outcomes, highlighting personalized treatment potential.
Area of Science:
- Audiology
- Otolaryngology
- Rehabilitation Medicine
Background:
- Unilateral cochlear implantation (CI) offers hearing restoration for sensorineural hearing loss.
- Assessing long-term, real-world benefits in diverse populations is crucial for routine clinical practice.
Purpose of the Study:
- To evaluate longitudinal, subjective benefits of unilateral CI in a multinational cohort.
- To identify predictors of self-reported outcomes following cochlear implantation.
Main Methods:
- Prospective, multicenter study with 291 unilateral CI recipients (aged 13-81).
- Validated self-assessment tools (SSQ, HUI3) used at pre-implantation and 1, 2, 3 years post-implantation.
- Longitudinal mixed-effects models analyzed outcomes, exploring demographic and clinical predictors.
Main Results:
- Significant improvements in all outcome measures (p < 0.0001) were observed.
- Post-implantation scores stabilized beyond 1 year, with individual variability.
- Pre-implantation hearing aid use, age, implantation side, comorbidities, dizziness, and tinnitus predicted outcomes (p < 0.004).
Conclusions:
- Standardized self-assessment tools effectively measure longitudinal CI benefits in routine multinational practice.
- Self-reported outcomes provide evidence for healthcare providers to support CI treatment decisions.
