Brief Summary
Purpose: Routine clinical care and pilot study data has shown evidence of postoperative hearing preservation in pediatric cochlear implant (CI) recipients. The primary aim of this study is to investigate speech perception performance in pediatric CI recipients with functional pre-operative hearing. Participants: Two cohorts of CI recipients aged 6 through 17 years who had pre-operative low frequency residual hearing. Subjects in Arm 1 (EAS Arm; electric-acoustic stimulation) will present with a post-operative low frequency pure tone average (125, 250, and 500 Hz) of ≤ 75 dB HL, and those in Arm 2 (FES Arm; full-electric stimulation) will present with a post-operative low frequency pure tone average (LFPTA) that exceeds 75 dB HL. Procedures (methods): Subjects will complete speech perception and quality of life testing during post-operative intervals. Subjects in the EAS Arm will be evaluated with combined electric-acoustic stimulation (EAS). Subjects in FES Arm will be evaluated with FES alone.

Outcome Measures
Primary Outcomes (2)
Mean CNC Word Scores
The Consonant Nucleus Consonant (CNC) word list is established as a standard test of speech perception outcomes. Results for EAS and FES Arms at 12 months post stimulation will be compared. Lower scores indicate a poorer outcome and higher scores a better outcome. Scale 0 - 100%
12 months post stimulation
Mean BKB-SIN SNR-50 Scores
Sentences and babble will be presented from the same speaker. An average score known as the SNR-50 will be obtained in both conditions. The SNR-50 score is an estimate of the signal-to-noise ratio associated with 50% correct based on word-level scoring. Results for EAS and FES listeners at 12 months post stimulation will be compared. In this test, lower scores indicate a better outcome and higher scores a poorer outcome. Scores range from -6 dB to +21 dB.
12 months post-stimulation

Study Arms (2)
EAS Arm
EXPERIMENTALSubjects who receive a CI and present with a post-operative LFPTA of ≤ 75 dB HL. Electric Acoustic Speech Processor: Electric-acoustic stimulation (EAS) fitting.
FES Arm
EXPERIMENTALSubjects with pre-operative low frequency hearing who receive a CI and present with a post-operative LFPTA of \> 75 dB HL. Electric Acoustic Speech Processor: Full-electric stimulation (FES) fitting
Interventions
Electric Acoustic Stimulation for children with post-operative residual low frequency hearing averages of 75 dB HL or better,
Electric Stimulation for children with post-operative residual low frequency hearing averages of 75 dB HL or poorer and pre-operative low frequency hearing averages of 75 dB HL or better.
Eligibility Criteria
You may qualify if:
- Aged 5 through 17 years
- Spoken English as the primary language (speech perception testing conducted in English).
- Recipient of a MED-EL SYNCHRONY Cochlear Implant device.
- Pre-operative LFPTA of ≤ 75 dB HL.
- Willing and able to participate in study procedures.
- Realistic parental/patient expectations.
- Language skills judged to be adequate enough to perform study tasks.
You may not qualify if:
- Inability to perform open set speech perception due to oral motor delays.
- Inability to perform test battery due to behavior or cognitive impairment
- Unwilling or unable to participate in study procedures.
- Cochlear nerve deficiency.
- Anatomical considerations that necessitated surgical modifications such as ossification, incomplete insertion, or placement in scala vestibuli.
