Cochlear Implantation Among Adults and Older Children with Unilateral or Asymmetric Hearing Loss
About this study
Do adults and older children (greater than 7 years of age) with unilateral or assymetric hearing loss benefit from cochlear implantation on the worst hearing side.
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.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.See eligibility criteria
