Summary
This review found significant variation in how speech perception is measured in Chinese-speaking adults with cochlear implants (CI). Most patients had long-term deafness before receiving a CI, highlighting a need for standardized outcome measures.
Area of Science:
- Audiology
- Otolaryngology
- Speech-Language Pathology
Background:
- Cochlear implantation (CI) is a vital treatment for severe to profound hearing loss.
- Understanding speech perception outcomes in diverse linguistic populations, such as Chinese speakers, is crucial for optimizing CI efficacy.
- Existing literature on Chinese-speaking adult CI users exhibits considerable variability.
Approach:
- A systematic review was conducted on English-language studies.
- Databases searched included PubMed, EMbase, and Scopus.
- Data extraction focused on speech perception outcomes and patient demographics, with qualitative and quantitative analyses.
Key Points:
- Forty-four studies involving 467 Chinese-speaking adult CI users were analyzed.
- Significant heterogeneity was observed in speech perception assessment methods and demographic reporting.
- The average duration of deafness prior to implantation was over 10 years, with most subjects having profound deafness for extended periods.
Conclusions:
- There is a lack of standardization in measuring speech perception outcomes and reporting demographics for Chinese-speaking adult CI recipients.
- Prolonged pre-implantation deafness is common in this population.
- Standardized outcome measures are needed to better evaluate CI benefits for tonal language speakers.
