Objective:
To evaluate the effects of related factors on long-term speech perception and quality-of-life (QoL) outcomes in postlingual deaf Mandarin-speaking adult cochlear implant (CI) recipients and to assess any differences between tone language and other intonation language CI adult users.
Study Design:
Retrospective cases review.
Setting:
Tertiary referral center.
Patients:
Forty-five adult CI recipients (48 implanted ears).
Main Outcome Measures:
Post-CI outcomes were evaluated after follow-ups of more than 24 months using speech perception tests and QoL questionnaires. We analyzed the related factors affecting CI outcomes.
Results:
A shorter duration of profound deafness was predictive factors for better post-CI speech perception. Earlier implantation and better performance of vowel scores were predictive of better subjective improvements in social and emotional life. Post-CI vowel scores of over 56% indicated promising improvements in QoL.
Conclusion:
Shorter duration of deafness could have better post-CI speech perception. Post-CI vowel scores instead of monosyllable words have the more potential to predict the QoL in Mandarin-speaking adult CI recipients.
