[Speech development test for 2-year-olds (2;0-2;11 years)-evaluation of multicentric data of children after bilateral cochlear implant treatment : A retrospective longitudinal study].

Background: Age-appropriate speech development is a primary aim of the rehabilitation of children treated with cochlear implants (CI). Various assessment tools are available, including the speech development test for 2‑year-olds (SETK-2). All tests are normalized to normal-hearing children; additionally, results are evaluated according to age and the duration of CI (hearing age).

[The LittlEARS® Auditory Questionnaire : An analysis of multicentre data of children after early bilateral cochlear implant placement].

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.

Fitting parameters in children with cochlear implants and severe additional disabilities.

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.

[Early language performance in the ELFRA questionnaire : Analysis of multicentre data from children with bilateral cochlear implants].

Background: Very early bilateral cochlear implant (CI) provision is today's established standard for children. Therefore, the assessment of preverbal and verbal performance in very early stages of development is becoming increasingly important. Performance data from cohorts of children were evaluated and presented based on diagnostic assessment using chronological age (CA) and hearing age (HA).

[COVID-19 hygiene measures at an inpatient CI therapy center for children from the parents' perspective].

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.

Multicentre evaluation of music perception in adult users of Advanced Bionics cochlear implants.

Objectives: To document musical listening and enjoyment in recipients of Advanced Bionics cochlear implants (CIs) and to compare musical perception in those using early coding strategies with subjects using the newer HiRes and HiRes 120 strategies.

Methods: A questionnaire was completed by 136 adult subjects, including questions on the ability to identify specific musical features. The subjects were in three groups: those using early coding strategies (n = 29), HiRes (n = 59), and HiRes 120 (n = 48), and results were compared with a group of 84 normally hearing (NH) subjects.

Improvements in speech perception after the upgrade from the TEMPO+ to the OPUS 2 audio processor.

Objective: To assess if speech perception improves after the upgrade from the TEMPO+ to the OPUS 2 processor.

Method: In this retrospective study, 45 subjects (54 ears) implanted with a cochlear implant were upgraded from the TEMPO+ (continuous interleaved sampling + coding strategy) to the OPUS 2 processor (fine structure processing). Before the upgrade, patients were tested with the Freiburg monosyllable (FM) and the Hochmair-Schulz-Moser (HSM) sentence test in quiet and in noise.
