Researchers have found that deaf children with a cochlear implant learn words even faster than those with normal hearing | Scientific Reports | via ScienceDaily
A current study at the Max Planck Institute for Human Cognitive and Brain Sciences has revealed that when deaf children get their cochlear implants, they learn words faster than those with normal hearing. Consequently, they build up certain word pools faster.
The reason for this finding could be that children with cochlear implants are older when they are first exposed to spoken language. Those with normal hearing learn aspects of language, such as the rhythm and melody of their mother tongue, from birth and even in the womb. In deaf children, this only starts at the time of their cochlear replacement, at the age of around one to four years. By this time certain brain structures necessary for language acquisition are already well developed.
The aim of the study was to investigate the impact of hearing aid (HA) and cochlear implant (CI) use on loneliness in adults| The Laryngoscope
One hundred and thirteen adults, aged ≥ 50 years, with postlingual hearing loss and receiving routine clinical care at a tertiary academic medical center, were evaluated with the University of California at Los Angeles Loneliness Scale before and 6 and 12 months after intervention with HAs or CIs. Change in score was assessed using linear mixed effect models adjusted for age; gender; education; and history of hypertension, diabetes, and smoking.
Treatment of hearing loss with CIs results in a significant reduction in loneliness symptoms. This improvement was not observed with HAs. We observed differential effects of treatment depending on the baseline loneliness score, with the greatest improvements observed in individuals with the most loneliness symptoms at baseline.
To study the postoperative impact of cochlear implants (CIs) on tinnitus, as well as the impact of tinnitus on speech recognition with CI switched on | Acta Oto-Laryngologica
Methods: Fifty-two postlingual deafened CI recipients (21 males and 31 females) were assessed using an established Tinnitus Characteristics Questionnaire and Tinnitus Handicap Inventory (THI) before and after cochlear implantation. The tinnitus loudness was investigated when CI was switched on and off in CI recipients with persistent tinnitus. The relation between tinnitus loudness and recipients’ satisfaction of cochlear implantation was analyzed by the visual analogue scale (VAS) score.
Results: With CI ‘OFF’, 42 CI recipients experienced tinnitus postimplant ipsilaterally and 44 contralaterally. Tinnitus was totally suppressed ipsilateral to the CI with CI ‘ON’ in 42.9%, partially suppressed in 42.9%, unchanged in 11.9% and aggravated in 2.4%. Tinnitus was totally suppressed contralaterally with CI ‘ON’ in 31.8% of CI recipients, partially suppressed in 47.7%, unchanged in 20.5%. Pearson correlation analysis showed that tinnitus loudness and the results of cochlear implant patients satisfaction was negatively correlated (r = .674, p < .001).
Conclusion: The study suggests six-month CI activation can be effective for suppressing tinnitus. The tinnitus loudness may affect patients’ satisfaction with the use of CI.
In the last 30 years, the field of cochlear implantation has rapidly evolved | Paediatrics and Child Health
Technological advances in hardware and corresponding developments in surgical techniques, along with new sound processing strategies and innovative rehabilitation, have combined to maximise functional outcomes. Informed by the evidence base of such outcomes, the inclusion criteria for children who might benefit from a cochlear implant (CI) has been refined and expanded. CIs are now the standard of care for children with severe to profound hearing loss where the desired outcome is spoken language. There are several emerging trends within the field of paediatric CIs that have already translated into clinical practice in some countries, but have not yet been universally adopted.
These include, but are not limited to, the expansion of audiometric CI candidacy criteria for cohorts with:
(1) more residual hearing;
(2) partial hearing which may benefit from electric-acoustic stimulation (EAS)
(3) asymmetric hearing levels. This review will describe the historical context and provide an overview of the candidacy trends as they relate to children.
Cochlear implantation (CI) is the most important and effective treatment for patients with profound sensorineural hearing loss. However, the outcomes of CI vary among patients | Acta Oto-Laryngologica
One of the reasons of this heterogeneous outcome for cochlear implantation is thought to be the heterogeneous nature of hearing loss. Indeed, genetic factors, the most common etiology in severe-to-profound hearing loss, might be one of the key determinants of outcomes for CI and electric acoustic stimulation (EAS). Patients with genetic causes involving an ‘intra-cochlear’ etiology show good CI/EAS outcomes.
This review article aimed to summarize the reports on CI/EAS outcomes in patients with special genetic causes as well as to assist in future clinical decision-making. Most of the cases were suspected of an intra-cochlear etiology, such as those with GJB2, SLC26A4, and OTOF mutations, which showed relatively good CI outcomes. However, there have only been a limited number of reports on patients with other gene mutations.
Most of the cases with gene mutations of intra-cochlear etiology showed relatively good CI outcomes. To progress toward more solid evidence-based CI intervention, a greater number of reports including CI outcomes for specific gene mutations are desired.
Deaf children with cochlear implants (CIs) are at risk for psychosocial adjustment problems, possibly due to delayed speech–language skills | The Journal of Deaf Studies and Deaf Education
This study investigated associations between a core component of spoken-language ability—speech intelligibility—and the psychosocial development of prelingually deaf CI users. Audio-transcription measures of speech intelligibility and parent reports of psychosocial behaviors were obtained for two age groups (preschool, school-age/teen). CI users in both age groups scored more poorly than typically hearing peers on speech intelligibility and several psychosocial scales.
Among preschool CI users, five scales were correlated with speech intelligibility: functional communication, attention problems, atypicality, withdrawal, and adaptability. These scales and four additional scales were correlated with speech intelligibility among school-age/teen CI users: leadership, activities of daily living, anxiety, and depression.
Results suggest that speech intelligibility may be an important contributing factor underlying several domains of psychosocial functioning in children and teens with CIs, particularly involving socialization, communication, and emotional adjustment.
A music-related quality of life (MuRQoL) questionnaire was developed for the evaluation of music rehabilitation for adult cochlear implant (CI) users. The present studies were aimed at refinement and validation | American Journal of Audiology
Method: Twenty-four experts reviewed the MuRQoL items for face validity. A refined version was completed by 147 adult CI users, and psychometric techniques were used for item selection, assessment of reliability, and definition of the factor structure. The same participants completed the Short Form Health Survey for construct validation. MuRQoL responses from 68 CI users were compared with those of a matched group of adults with normal hearing.
Results: Eighteen items measuring music perception and engagement and 18 items measuring their importance were selected; they grouped together into 2 domains. The final questionnaire has high internal consistency and repeatability. Significant differences between CI users and adults with normal hearing and a correlation between music engagement and quality of life support construct validity. Scores of music perception and engagement and importance for the 18 items can be combined to assess the impact of music on the quality of life.
Conclusion: The MuRQoL questionnaire is a reliable and valid measure of self-reported music perception, engagement, and their importance for adult CI users with potential to guide music aural rehabilitation.
