[Language development test for 3-5-year-old children (3;0-5;11 years)-diagnostics of language and auditory memory : Retrospective analysis of children with bilateral cochlear implantation in early childhood].

Background: Fitting of a cochlear implant (CI) influences the development of auditory memory and thus the development of speech. Speech development is a prerequisite for the acquisition of written language and reading and, thus, the later educational biography.

Materials And Methods: Language development tests for 3-5-year-old children (SETK 3-5) represent a standardized procedure to assess receptive and expressive speech development as well as auditory memory.

[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.

[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).
