An observational study in Severe Unilateral Sensorineural Hearing Loss, sponsored by Mayo Clinic. Completed at 1 site in United States. Open to participants aged 7 Years and older. Per ClinicalTrials.gov, last updated 2018-04-05.
Sponsored by Mayo Clinic · Observational
Do adults and children over 7 years of age with unilateral or assymetric hearing loss benefit from cochlear implantation on the worst hearing side.
Unilateral hearing loss is known to impair binaural hearing abilities. Specifically, localization, speech understanding in noise, and binaural squelch suffer due to lack of binaural timing and level cues. This study is designed to examine how binaural hearing is improved following cochlear implantation on the impaired side. The study endpoints are collected at 6 months and 12 months post activation of the implant.
This is not a funded study. All costs are billed through insurance for reimbursement. There is an insurance approval process that we move through after a participant has been evaluated at the Mayo Clinic and found to be a candidate for cochlear implantation.

How well patients with cochlear implants understand speech in noise with implant on, compared to implant off.
Device: Cochlear implant
Implantable hearing device
Listening Effort
A dual task performance paradigm will be used in which both the primary task and the secondary task will be performed simultaneously. The primary task will consist of speech recognition testing in varying levels of background noise and quiet, whereas the secondary task will consist of a motor reaction to a randomly presented light
Time frame: one year post operative test time
