AbstractAim: This is a series of studies with prospective, observational, within-subjects repeated-measure design, having been conducted in a tertiary referral cochlear implant clinic since 6 years ago (IRB Approvals CREC 2014.014, 2017.537-T). These studies aim to investigate the benefits of cochlear implant systems of various brands and models, in persons with unilateral or asymmetric severe to profound hearing loss, in particular on tinnitus suppression in the implanted ear.

Material and Methods: Adults or children aged 6 years or above were recruited in this series of studies. There was a series of participants (n=9) received the Advanced Bionics HiRes 90K Advantage implant with HiFocus 1J or HiFocus Mid-Scala electrode array, and another series of participants (n=10) received the Cochlear N6 implant with CI532 electrode. Both systems were commercially available.

Validated and culturally appropriate tinnitus assessment battery, including tinnitus subjective loudness visual analogue scale (VAS), tinnitus matching on loudness, tinnitus distress questionnaire, hospital anxiety and depression scale (HADS), tinnitus questionnaire (TQ), and tinnitus handicap inventory (THI) have been administered at time-points including baseline, post 1, 3, 6, 12, and 24 months after device activation.

This is an ongoing series of studies. Some of the participants are currently at the data collection time-point of 6 to 12 months after device activation.

Results: A clear trend of decreasing tinnitus loudness, as well as the distress caused by the tinnitus, has been observed over time across the two independent series of participants. A significant proportion of participants reported that the tinnitus has been no longer noticeable since the activation of the device.

Conclusion: Cochlear implantation for persons with unilateral or asymmetric severe to profound hearing loss is currently not yet a well-adopted treatment modality. Its benefits and efficacy on tinnitus suppression among this specific clinical population are however promising.
