“…The observed effects on tinnitus after completing the standard CI rehabilitation phase are in line with previous studies Kleinjung et al, 2009;Arndt et al, 2010;Buechner et al, 2010;Palau et al, 2010;Jacob et al, 2011;Kleine Punte et al, 2011;Firszt et al, 2012b;Ramos et al, 2012;Hansen et al, 2013;Távora-Vieira et al, 2013]. Our results show a decrease in tinnitus perception over the approximately 8 weeks of CI rehabilitation that is not caused by the surgery itself, which is consistent with an earlier case report [Gartrell et al, 2014].…”

“…Nevertheless, tinnitus can also be a complication after cochlear implantation [Di Nardo et al, 2007;Postelmans et al, 2007;Hou et al, 2010], possibly related to cochlear damage due to the surgery [Nordfalk et al, 2014;Todt et al, 2014]. Van de Heyning et al [2008] reported the first results of cochlear implantation in an attempt to treat tinnitus in single-sided deafness (SSD), after which many studies followed on tinnitus suppression in SSD [Kleinjung et al, 2009;Arndt et al, 2010;Buechner et al, 2010;Palau et al, 2010;Jacob et al, 2011;Kleine Punte et al, 2011;Firszt et al, 2012b;Mendes et al, 2012;Ramos et al, 2012;Hansen et al, 2013;Távora-Vieira et al, 2013 and reviewed by Arts et al, 2012;Blasco and Redleaf, 2014;Tokita et al, 2014;Vlastarakos et al, 2014;van Zon et al, 2015]. As a common conclusion it can be stated that cochlear implantation is a viable treatment option for tinnitus in SSD.…”

Tinnitus Suppression by Intracochlear Electrical Stimulation in Single-Sided Deafness: A Prospective Clinical Trial - Part I

Cochlear implantation is a viable treatment option for tinnitus, but the underlying mechanism is yet unclear. Is the tinnitus suppression due to the reversal of the assumed maladaptive neuroplasticity or is it the shift in attention from the tinnitus to environmental sounds and therefore a reduced awareness that reduces tinnitus perception? In this prospective trial, 10 patients with single-sided deafness were fitted with a cochlear implant to investigate the effect of looped intracochlear electrical stimulation (i.e. stimulation that does not encode environmental sounds) on tinnitus, in an effort to find optimal stimulation parameters. Variables under investigation were: amplitude (perceived stimulus loudness), anatomical location inside the cochlea (electrode/electrodes), amplitude modulation, polarity (cathodic/anodic first biphasic stimulation) and stimulation rate. The results suggest that tinnitus can be reduced with looped electrical stimulation, in some cases even with inaudible stimuli. The optimal stimuli for tinnitus suppression appear to be subject specific. However, medium-to-loud stimuli suppress tinnitus significantly better than soft stimuli, which partly can be explained by the masking effect. Although the long-term effects on tinnitus would still have to be investigated and will be described in part II, intracochlear electrical stimulation seems a potential treatment option for tinnitus in this population.

“…Although a contralateral routing of the signal (CROS) may be beneficial in some situations, it does not restore hearing to the poor ear and, in some cases, has been detrimental [Hol et al 2004; Hol et al 2010; Wazen et al 2005]. Cochlear implantation as a treatment for adults with UHL is on the rise [Arndt et al 2011; Buechner et al 2010; Firszt et al 2012; Jacob et al 2011; Ramos et al 2012], yet little is known about factors that could impact performance or whether there is a group at risk for poor outcomes when hearing is near-normal in one ear. Likewise in children with UHL, predictive variables for cochlear implant success are unknown, and whether these factors change developmentally has not been determined.…”

The study objective was to quantify abilities of children with unilateral hearing loss (UHL) on measures that address known deficits for this population, i.e. speech understanding in quiet and noise, and sound localisation. Noise conditions varied by noise type and source location. Parent reports of real-world abilities were also obtained. Performance was compared to gender- and age-matched normal hearing (NH) peers. UHL performance was poorer and more varied compared to NH peers. Among the findings, age correlated with localisation ability for UHL but not NH participants. Low-frequency hearing in the better ear of UHL children was associated with performance in noise; however, there was no relation for NH children. Considerable variability was evident in the outcomes of children with UHL and needs to be understood as future treatment options are considered.

Purpose of review Recently, more patients with single-sided deafness (SSD) have been undergoing cochlear implantation. We review recent studies and case reports to provide an overview of the efficacy of cochlear implants (CIs) to rehabilitate patients with SSD with regards to sound localization, speech discrimination, and tinnitus suppression. Recent findings There are a growing number of studies evaluating the effect of cochlear implantation for rehabilitation of the deficits associated with SSD over the past several years as more centers offer this treatment modality to patients with SSD. While individual studies have few subjects and are underpowered, the vast majority report improvement in sound localization, speech understanding in quiet and noise, and tinnitus. In some cases the outcomes with CI appear superior to those achieved with other devices including contralateral routing of sound (CROS) devices and osseointegrated implants (OIs). Summary Although CI is not an FDA-approved treatment for SSD, several recent studies show improvements in speech understanding, sound localization, and tinnitus. Due to the low number of cases, it is difficult to conclusively compare outcomes achieved with CIs and those provided by other devices. However, based on encouraging early results and the unique ability to restore binaural sound processing, a growing number of centers offer CIs as treatment for SSD. Forthcoming studies will help define outcome expectations in different populations.
