Primary Outcome Measures:
  • Subject performance on speech perception tests [ Time Frame: Two years post device activation ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Speech recognition performance at various intervals. Global quality of life and functional communicative performance completed by parental proxy [ Time Frame: 3, 6, 12, 18, and 24 months post device activation ] [ Designated as safety issue: No ]

Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 Device: HiResolution Bionic Ear System (Cochlear Implant)
Subjects are required to have bilateral implantation of the Advanced Bionics HiResolution Bionic Ear System (Cochlear Implant)

Detailed Description:

The primary purpose of this study is to track patient outcomes for bilateral cochlear implant recipients in a cohort of children, ages 12 to 36 months at time of surgery, who receive two implants in the same operation or in two different surgeries with the initial fitting of the devices separated by no more than six months. Acquisition of auditory milestones and speech recognition skills, which underpin the development of spoken language, will be assessed on a battery of outcome measures typically used to quantify implant benefits. In addition, global quality of life and communicative performance will be assessed by parental proxy. Performance will be tracked after 3, 6, 12, 18, and 24 months of device use. The study also will identify variables that may predict the degree of bilateral implant benefit in young children (e.g., age at implant, pre-implant hearing thresholds, communication mode, family socioeconomic status, post-implant aided thresholds, simultaneous vs. staged placement of devices).

  Eligibility

Ages Eligible for Study:   12 Months to 36 Months
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Profound bilateral hearing loss (PTA>= 90dB HL)
  • Have independently elected to undergo bilateral implantation of Advanced Bionics HiResolution Bionic Ear System and meet all the eligibility criteria for this device as described in the product labeling.
  • Age at implant: 12-36 months
  • Negligible benefit from hearing aids, defined as failure to reach developmentally appropriate milestones on IT-MAIS
  • No previous cochlear implant use
  • Normal/patent cochlea with no more than a mild "partitioning" defect in either ear
  • English as the primary language spoken in the home
  • Parental willingness to follow study protocol

Exclusion Criteria:

  • Deafness secondary to meningitis
  • Presence of other conditions that could affect performance on outcome measures or otherwise confound or interfere with study participation of outcomes measures.
