Overview
The aim of the study is to assess the continued efficacy and safety of cochlear implantation in participants aged 5 years and above with Unilateral Hearing Loss (UHL)/Single Sided Deafness (SSD) supporting a change indication for use.
Eligibility
Inclusion Criteria:
• Individuals 18 years or older (Group A)
Ear to be Implanted:
Severe sensorineural hearing loss (HL) defined as: Pure-tone average at 0.5, 1, 2, 4 kHz >80 dB HL ; Aided Consonant-Nucleus-Consonant Test (CNC) score ≤5% and
Normal Hearing Ear:
Normal or near normal hearing defined as an average of (0.5, 1, 2, 4kHz) ≤ 30 dB HL
• Children 5 years to 17 years, 11 months (Group B)
Ear to be Implanted:
Severe sensorineural HL defined as: Pure-tone average at 0.5, 1, 2, 4 kHz >80 dB HL; Aided CNC score ≤5% and
Normal Hearing Ear:
Normal or near normal hearing defined as an average of (0.5, 1, 2, 4kHz) ≤ 30 dB HL
- Previous experience with a current conventional treatment option for unilateral [SSD] HL (HA, bone-conduction device, or CROS technology), if no previous experience a minimum trial period of two weeks is required
- English spoken as a primary language
- Willing and able to provide written informed consent
Exclusion Criteria:
- Ossification, abnormal cochlear nerve or any other cochlear anomaly that might prevent complete insertion of the electrode array

- Medical or psychological conditions that contraindicate undergoing surgery as determined by the Investigator
- Unrealistic expectations on the part of the participant/family, regarding the possible benefits, risks, and limitations that are inherent as determined by the Investigator
- Evidence of and/or suspected cognitive or developmental concern
- Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator
- Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child or sibling

- Pregnant or breastfeeding women
- Currently participating, or participated within the last 30 days, in another interventional clinical investigation/trial involving an investigational drug or device.
