Summary
Shorter deafness duration improves cochlear implant (CI) speech perception. Post-CI vowel scores predict quality of life (QoL) in Mandarin speakers, offering better insights than monosyllable tests.
Area of Science:
- Audiology
- Otolaryngology
- Rehabilitation Medicine
Background:
- Cochlear implantation (CI) is a treatment for severe to profound hearing loss.
- Understanding factors influencing long-term outcomes in diverse linguistic populations is crucial.
Purpose of the Study:
- To identify factors affecting speech perception and quality of life (QoL) in postlingual deaf Mandarin-speaking adult CI recipients.
- To compare outcomes between tone language and other intonation language users.
Main Methods:
- Retrospective case review of 45 adult CI recipients (48 ears) at a tertiary referral center.
- Evaluation of post-CI outcomes (speech perception, QoL) after >24 months follow-up.
- Analysis of factors influencing CI outcomes.
Main Results:
- Shorter duration of profound deafness predicted better post-CI speech perception.
- Earlier implantation and higher vowel scores predicted improved social/emotional QoL.
- Post-CI vowel scores >56% indicated promising QoL improvements.
Conclusions:
- Reduced duration of deafness is a key factor for enhanced speech perception after cochlear implantation.
- Post-CI vowel scores are more predictive of QoL in Mandarin-speaking adults than monosyllable word scores.
