Summary
Objective hearing tests do not fully capture cochlear implant (CI) users' experiences. Questionnaires assessing subjective hearing are crucial for comprehensive CI evaluation, alongside objective measures.
Area of Science:
- Audiology
- Otorhinolaryngology
- Biomedical Engineering
Background:
- Cochlear implantation (CI) assessment traditionally relies on objective tests.
- Patient subjective experiences are increasingly vital in healthcare.
- Evaluating the correlation between subjective and objective hearing tests in CI users is important.
Purpose of the Study:
- To analyze the correlation between subjective (questionnaires) and objective (speech perception, localization) hearing test results in adult CI users.
- To compare these correlations between unilateral and bilateral CI patients.
Main Methods:
- Prospective data collection from a multicentre randomized controlled trial.
- 38 adult CI patients (19 unilateral, 19 bilateral) followed for one year.
- Correlations assessed using Speech, Spatial and Qualities of Hearing Scale (SSQ) and Nijmegen Cochlear Implant Questionnaire (NCIQ) against objective speech perception and localization tests.
Main Results:
- Significant weak to moderate negative correlations found between subjective speech perception (SSQ, NCIQ) and objective speech-in-noise tests (r = -0.33 to -0.48).
- A significant moderate correlation observed between subjective spatial hearing (SSQ) and objective localization tests (r = 0.59).
- Correlations did not significantly differ between unilateral and bilateral CI groups.
Conclusions:
- Objective tests alone do not fully represent subjective, real-world listening experiences for CI users.
- Questionnaires are essential for a comprehensive evaluation of cochlear implantation outcomes.
- Regular assessment of both objective and subjective tests is recommended for CI patients.
