Na E, Toupin-April K, Olds J, Chen J, Fitzpatrick EM. Benefits and risks related to cochlear implantation for children with residual hearing: a systematic review. Int J Audiol 2024; 63:75-86. [PMID: 36524877 DOI: 10.1080/14992027.2022.2155879] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 11/24/2022] [Accepted: 11/30/2022] [Indexed: 12/23/2022]
Abstract
OBJECTIVE This study aimed to synthesise information concerning the potential benefits and risks related to cochlear implants (CIs) versus hearing aids (HAs) in children with residual hearing. DESIGN A systematic review of articles published from January 2003 to January 2019 was conducted. STUDY SAMPLE Our review included studies that compared the benefits and risks of CIs versus HAs in children (≤18 years old) with residual hearing. A total of 3265 citations were identified; 8 studies met inclusion criteria. RESULTS Children with CIs showed significantly better speech perception scores post-CI than pre-CI. There was limited evidence related to improvement in everyday auditory performance, and the results showed non-significant improvement in speech intelligibility. One study on social-emotional functioning suggested benefits from CIs. In four studies, 37.2% (16/43) of children showed loss of residual hearing and 14.0% (8/57) had discontinued or limited use of their device. CONCLUSIONS Children with CIs showed improvement in speech perception outcomes compared to those with HAs. However, due to the limited number of studies and information to guide decision-making related to other areas of development, it will be important to conduct further research of both benefits and risks of CIs in this specific population to facilitate decision-making.

Pignac S, Sygal N, Biglari M, Olds J, Fitzpatrick EM. Determining cochlear implant candidacy in children with residual hearing: A scoping review. Int J Pediatr Otorhinolaryngol 2024; 177:111855. [PMID: 38190764 DOI: 10.1016/j.ijporl.2024.111855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 10/20/2023] [Accepted: 01/02/2024] [Indexed: 01/10/2024]
Abstract
OBJECTIVES The purpose of this review was to summarize what is known about criteria, assessments, and recommendations for evaluating cochlear implant (CI) candidacy in children with residual hearing. METHODS Peer-reviewed studies were identified through a systematic search in five electronic databases. Articles were screened and assessed for eligibility. From the eligible studies, data were extracted to summarize and present a narrative synthesis of the findings. RESULTS A total of seven articles (two reviews and five primary studies) were included in the final analysis. Hearing levels better than the moderately severe to severe range (65-90 dB HL) tend to be supported as audiological candidacy criteria for pediatric CI. Recommendations for candidacy consideration based on audiologic thresholds range from 65 to 80 dB Hl pure-tone average as the lower boundary. Our review did not identify any specific assessment protocols. However, additional decision-making considerations related to borderline hearing loss configurations and assessment tools (the Speech Intelligibility Index and the Pediatric Minimum Speech Test Battery) were identified. Supplementary assessment considerations were also reported. CONCLUSION There is limited information regarding specific assessment protocols for children with residual hearing. The literature is primarily focused on guidelines related to audiologic criteria, although it is widely recommended that other areas of functioning should also be considered. Most recommendations appear to be based on expert opinion, clinical expertise, and evidence from overall pediatric CI outcomes rather than empirical evidence targeting children with residual hearing. There is an ongoing need for research to further develop protocols and tools that can assist clinicians and families in making cochlear implantation decisions for children with residual hearing.

Abstract
OBJECTIVES The purpose of this study was to determine the prevalence of ceiling effects for commonly used speech perception tests in a large population of children who received a cochlear implant (CI) before the age of four. A secondary goal was to determine the demographic factors that were relevant for predicting which children were more likely to reach ceiling level performance. We hypothesize that ceiling effects are highly prevalent for most tests. DESIGN Retrospective chart review of children receiving a CI between 2002 and 2014. RESULTS 165 children were included. Median scores were above ceiling levels (≥90% correct) for the majority of speech perception tests and all distributions of scores were highly skewed. Children who were implanted earlier, received two implants, and were oral communicators were more likely to reach ceiling-level performance. Age and years of CI listening experience at time of test were negatively correlated with performance, suggesting a non-random assignment of tests. Many children were re-tested on tests for which they had already scored at ceiling. CONCLUSIONS Commonly used speech perception tests for children with CIs are prone to ceiling effects and may not accurately reflect how a child performs in everyday listening situations.

Abstract
OBJECTIVES The purpose of this study was to determine if traditional audiologic measures (e.g., pure-tone average, speech recognition) and audibility-based measures predict risk for spoken language delay in children who are hard of hearing (CHH) who use hearing aids (HAs). Audibility-based measures included the Speech Intelligibility Index (SII), HA use, and auditory dosage, a measure of auditory access that weighs each child's unaided and aided audibility by the average hours of HA use per day. The authors also sought to estimate values of these measures at which CHH would be at greater risk for delayed outcomes compared with a group of children with typical hearing (CTH) matched for age and socioeconomic status, potentially signaling a need to make changes to a child's hearing technology or intervention plan. DESIGN The authors compared spoken language outcomes of 182 CHH and 78 CTH and evaluated relationships between language and audiologic measures (e.g., aided SII) in CHH using generalized additive models. They used these models to identify values associated with falling below CTH (by > 1.5 SDs from the mean) on language assessments, putting CHH at risk for language delay. RESULTS Risk for language delay was associated with aided speech recognition in noise performance (<59% phonemes correct, 95% confidence interval [55%, 62%]), aided Speech Intelligibility Index (SII < 0.61, 95% confidence internal [.53,.68]), and auditory dosage (dosage < 6.0, 95% confidence internal [5.3, 6.7]) in CHH. The level of speech recognition in quiet, unaided pure-tone average, and unaided SII that placed children at risk for language delay could not be determined due to imprecise estimates with broad confidence intervals. CONCLUSIONS Results support using aided SII, aided speech recognition in noise measures, and auditory dosage as tools to facilitate clinical decision-making, such as deciding whether changes to a child's hearing technology are warranted. Values identified in this article can complement other metrics (e.g., unaided hearing thresholds, aided speech recognition testing, language assessment) when considering changes to intervention, such as adding language supports, making HA adjustments, or referring for cochlear implant candidacy evaluation.

Abstract
PURPOSE Cochlear implants (CIs) are increasingly considered for children with residual hearing who benefit from hearing aids (HAs). However, the decision-making process for families of these children and for practitioners is particularly challenging because there is no clear audiological cut point for CI candidacy. This study aimed to understand Canadian practitioners' perspectives of the CI decision-making process and how they guide families of children with residual hearing. METHOD Semistructured interviews were conducted with a total of 17 practitioners through four focus groups and one individual interview. Interviews were transcribed verbatim, and a thematic analysis was carried out. RESULTS Data were organized into five broad domains: candidacy issues for children with residual hearing, practitioners' roles in decision support, additional considerations affecting decision making, factors facilitating decision making, and practitioners' needs. CONCLUSIONS This study found that practitioners' confidence in determining candidacy and supporting parents has increased due to their experiences with positive outcomes for these children. Practitioners indicated that there was a need for more research to guide the decision-making process.

Abstract
In 2020, the lower age limit for pediatric cochlear implant candidacy was lowered from 12 to 9 months of age. However, audiometric-based criteria for pediatric cochlear implant candidacy have remained unchanged for more than 20 years, requiring bilateral profound sensorineural hearing loss for children less than 2 years and bilateral severe-to-profound sensorineural hearing loss for children 2 years and older. Despite the static audiometric criteria, there is an increasing literature base demonstrating significant benefits for pediatric cochlear implant recipients who exceed current Food and Drug Administration-labeled indications for cochlear implantation.
