Outcome Measures

Primary Outcomes (2)

  • Change in Speech recognition in quiet

    Change in Speech recognition in quiet will be assessed using the percent correct on Consonant-Noun-Consonant words and phonemes.

    Baseline and up to 1 year post-implantation

  • Change in Speech recognition in noise

    Change in Speech recognition in noise will be assessed using the percent correct on AzBio with multitalker babble at 8dB signal-to-noise ratio.

    Baseline and up to 1 year post-implantation

Secondary Outcomes (4)

  • Change in Spatial hearing as assessed by the Spatial Hearing Questionnaire

    Baseline and up to 1 year post-implantation

  • Change in Tinnitus handicap as assessed by the Tinnitus Handicap Inventory

    Baseline and up to 1 year post-implantation

  • Change in Hearing aid benefit as assessed by the Abbreviated Profile of Hearing Aid Benefit

    Baseline and up to 1 year post-implantation

  • Change in Health utility as assessed by the Health Utility Index

    Baseline and up to 1 year post-implantation

Study Arms (1)

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study population comprises individuals with single-sided deafness or asymmetric hearing loss resulting in poor hearing in one ear.

You may qualify if:

  • For individuals ages 18 years-old and above, limited benefit from unilateral amplification is defined by test scores of 5% correct or less on monosyllabic consonant-nucleus-consonant (CNC) words in quiet when tested in the ear to be implanted alone.
  • Before implantation with a cochlear implant, individuals with SSD or AHL must have at least 1-month experience wearing a Contra Lateral Routing of Signal (CROS) hearing aid or other relevant device and not show any subjective benefit.
  • Medical and surgical clearance for cochlear implantation.

You may not qualify if:

  • Not meeting FDA candidacy criteria for cochlear implantation in SSD
  • Inability to perform audiologic tasks (e.g. non-English speaking)
  • Medical or surgical contraindication to general anesthesia or cochlear implant surgery
  • Does not wish to participate
