RESUMEN
BACKGROUND: In order to optimise the support of children with cochlear implants (CI), it is very important to detect slow developmental processes as early as possible. Data from the LittlEARS® Auditory Questionnaire (LEAQ) from children with early bilateral CI are evaluated and presented in relation to age and hearing age and compared with language development data recorded later. MATERIALS AND METHODS: This retrospective multicentre study included data from a total of 554 children for whom at least one LEAQ was completed during the course of CI rehabilitation. Children without additional disabilities who received bilateral simultaneous or sequential CI treatment were included. RESULTS: As expected, there are high correlations between hearing age (HA) and the overall LEAQ total score. When analysed according to chronological age (CA), development runs roughly parallel to the development of children with normal hearing, albeit at a lower level. Children implanted early up to an age of ≤â¯12 months consistently achieve approximately 7-8 raw points more. Only the LEAQ results of the later test times (from the age of 18 months) correlate with some areas of the speech development test for children (SETK; areas 3-5). CONCLUSION: The earliest possible detection of critical developmental processes in children with CI is extremely important. In the case of very early CI fitting, the CA should be used as a reference measure in diagnostics. The LEAQ values determined for the group of children with CI are suitable to a limited extent as generally valid reference values for children with early bilateral CI. Further studies should continue to work out the correlations between early preverbal development and later speech development.
RESUMEN
PURPOSE: The aim of this study was to investigate whether the fitting data of children with Cochlear implants (CI) and severe additional disabilities (CAD) differ compared to children with CI but without additional disabilities (CnonAD). METHODS: In this retrospective analysis, 76 CI cases (fitted ears) from CAD were included and matched with 76 cases from CnonAD. The subjective set values, such as pulse width (PW), threshold (T) and most comfortable (MC) levels were recorded. Additionally, the response threshold values by means of aided soundfield threshold (AST), the values of the intracochlear electrode impedances, the eCAP thresholds and the daily wearing time by using data logging were recorded and analysed. RESULTS: The T and MC levels for the Medel implants were significantly lower in the sample than in the control group. A similar trend was evident for Cochlear® implants. The sample showed a positive correlation between the eCAP thresholds and the T level and MC level in case of the Cochlear implants. The CAD group showed a significantly higher aided soundfield threshold. In contrast to the CnonAD (0%), there was a total of 18% in the CAD with a reduced daily wearing time. When these were excluded, eCAP thresholds were significantly higher in the CAD group. In addition, there was a trend for eCAP thresholds to be higher if the contralateral ear was not also fitted with a CI. CONCLUSIONS: The significantly higher eCAPs in CAD may be explained by different neural survival but also by different fittings and MC levels. The audiuologist's subjectivity must be considered as a potential bias but also as potentially valuable input variable contributing to the variance in the fitting parameters and outcomes. Better fitting of T and MC levels focusing on behavioural and developmental responses may lead to a longer wearing time. To support the audiologist and the fitting process, it is necessary to interpret the response thresholds in the aided soundfield threshold against the background of the medical diagnosis and observations from everyday life should be considered. To ensure optimal development of CAD children according to their individual abilities, a multi-professional, family-centred intervention programme including videoanalyses should be implemented at an early stage, ideally from the decision process for a cochlear implant.
RESUMEN
BACKGROUND: Due to the COVID-19 pandemic, all essential treatment must adhere to strict health and hygiene protocols. New measures have been introduced in CI treatment centres in order to safely accommodate families and continue to provide effective follow-up CI therapy for children implanted with CIs. OBJECTIVES: The aim of this study was to document, over the course of the pandemic, how patients' parents viewed the likelihood and danger of infection and how necessary they thought the newly implemented protocols were. MATERIALS AND METHODS: All parents of children implanted with CIs who participated in therapy at the CIC treatment centre between August and November 2020 (Nâ¯= 255) were requested to fill out a questionnaire anonymously following their stay. RESULTS: 255 questionnaires were distributed, 83 (32.5%) of which were filled out. During the course of the study, there was an increase in the parents' perceived risk of infection. Simultaneously, fewer parents felt well protected at the CIC. According to parents, the new hygiene protocols at the CIC did not negatively affect treatment. However, many parents noted that their interactions with other patient families had been better prior to introduction of the hygiene protocols. CONCLUSIONS: The CIC`s hygiene protocols were well received. However, data analysis over the course of the study suggests that hygiene protocols were not sufficient to prevent fear of infection in light of increasing rate of infection.
