Study Details

Study Description

Brief Summary

The purpose of this investigation is to demonstrate the safety and effectiveness of MED-EL cochlear implants in children 7 months to 5 years, 11 months of age who fall outside the current FDA-approved candidacy criteria and, yet, continue to demonstrate insufficient functional access to sound with appropriately fit hearing aids and aural habilitation.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Prospective

Detailed interventions and outcome measures refer to the prospective, experimental study arm. The prospective arm is active but not enrolling.

Device: MED-EL SYNCHRONY PIN Cochlear Implant
Subjects will be implanted with the MED-EL SYNCHRONY PIN Cochlear Implant System with +FLEX24, +FLEX28, +FLEXSOFT electrode arrays. Subjects will be fit with the SONNETEAS (ear-level) and/or RONDO 2 (single-unit) external audio processors.
Other Names:
  • SYNCHRONY +FLEXSOFT
  • SYNCHRONY +FLEX28
  • SYNCHRONY +FLEX24
  • Other: Retrospective

    Study identification, sponsor/collaborators, oversight, purpose, indications, and primary endpoints for the retrospective, observational study arm align with the prospective study arm. The retrospective arm will be enrolling by invitation for chart review of subjects implanted with a MED-EL cochlear implant under 6 years of age between January 2005 and October 2020. The specific devices and outcome measures will vary slightly for retrospective subjects, based on what was clinically available and used at the time of implantation.

    Other: Cochlear Implant
    Chart review of subjects implanted with a MED-EL cochlear implant under 6 years of age between January 2005 and October 2020.

    Outcome Measures

    Primary Outcome Measures

    1. Total Score on LittlEARS Auditory Questionnaire (LEAQ) [Up to 12 Months Post-Activation]

      Clinical success defined as a Total Score of 25 or more on the LittLEARS Auditory Questionnaire (LEAQ). Total Score ranges from zero to 35, with higher scores indicating development of increasingly complex listening skills.

    2. Percent correct on Multisyllabic Lexical Neighborhood Test (MLNT)/Lexical Neighborhood Test (LNT) [Up to 12 Months Post-Activation]

      Clinical success defined as an improvement of 10 percentage points or more on MLNT/LNT.

    3. Number and proportion of subjects experiencing device- and/or procedure-related adverse events. [Up to 12 Months Post-Activation]

      Adverse events will be collected and reported throughout the duration of the study.

    Secondary Outcome Measures

    1. Total Score on LittlEARS Auditory Questionnaire (LEAQ) [Up to 12 Months Post-Activation]

      Change from baseline in Total Score on the LittlEARS Auditory Questionnaire (LEAQ). Total Score ranges from zero to 35, with higher scores indicating development of increasingly complex listening skills. The LittlEARS Auditory Questionnaire is intended for young children with zero to 24 months of listening experience.

    2. Total Score on Auditory Skills Checklist (ASC) [Up to 12 Months Post-Activation]

      Change from baseline in Total Score on the Auditory Skills Checklist (ASC). Total Score ranges from zero to 70, with higher scores indicating development of increasingly complex listening skills. The Auditory Skills Checklist is intended for children from zero to 18 years of age.

    3. Speech recognition testing in the implanted ear(s) [Up to 12 Month Post-Activation]

      Percent change from baseline scores on speech recognition testing with words in quiet and sentences in quiet and noise.
