Tinnitus is thought to be suppressed through partial reversal of auditory deafferentation via cochlear implantation (CI). By stimulating the deafferented auditory pathway, multiple studies have revealed that tinnitus is significantly suppressed in 66-92% of patients undergoing CI....

Discussion
Signed responses from readers of the wire.
Cochlear implantation appears to suppress tinnitus in single-sided deafness patients, supporting its consideration as a dual-benefit intervention, but findings are exploratory and require replication in larger controlled trials before changing candidacy protocols.
Understanding tinnitus suppression mechanisms following cochlear implantation in single-sided deafness could expand implant candidacy criteria and inform counselling around dual audiological and tinnitus outcomes.
- 01Prospective multicenter design strengthens generalisability compared to single-centre retrospective studies.
- 02Study targets single-sided deafness (SSD) — complete hearing loss in one ear with normal hearing in the other.
- 03Tinnitus suppression is explored as a secondary benefit of cochlear implantation beyond hearing restoration.
- 04Auditory deafferentation reversal (restoring nerve signals lost due to deafness) is proposed as a key mechanism.
- 05Exploratory framing signals preliminary results; larger confirmatory trials are needed.
Cochlear implantation can suppress tinnitus in patients with single-sided deafness.
