“…This may result in a change of spontaneous neural activity in the central auditory system, which is believed to potentially cause tinnitus. Cochlear implantation may attenuate tinnitus, as is obvious from several previous reports on the effect of hearing rehabilitation on tinnitus, possibly due to the restoration of afferent input to the brainstem [Baguley and Atlas, 2007;Quaranta et al, 2008;Bovo et al, 2011]. It would be expected that 1-sided cochlear implantation would decrease tinnitus in the implanted ear.…”

“…The first report of subjective tinnitus being suppressed by a cochlear implant was published by House [1976]. After that, several studies have confirmed these results, showing that suppression of tinnitus occurs in 15-95% of the cases [Rubinstein et al, 2003;Quaranta et al, 2008;Van de Heyning et al, 2008;Akdogan et al, 2009;Pan et al, 2009;Bovo et al, 2011;Kompis et al, 2012]. However, some cochlear implant patients have reported an exacerbation (1-10%) or the onset (0-23.5%) of tinnitus after implantation [Baguley and Atlas, 2007;Quaranta et al, 2008;Akdogan et al, 2009;Bovo et al, 2011;Kompis et al, 2012].…”

This study retrospectively assessed the prevalence of tinnitus in cochlear implant patients and the changes after implantation in 212 patients implanted between 2000 and 2009. Patients were included at least 6 months after implantation and received 2 sets of questionnaires, one about the situation before implantation and one about the situation after implantation. Mostly standardized questionnaires assessed tinnitus handicap (Tinnitus Handicap Inventory, THI, and Tinnitus Handicap Questionnaire, THQ), tinnitus characteristics, hearing loss (Abbreviated Profile of Hearing Aid Benefit) and anxiety/depression (Hospital Anxiety and Depression Scale). Of the approached patients, 117 completed the full sets of questionnaires and 35 completed a short version. Preoperative tinnitus was reported by 51.3% of these patients, of which 55.6% reported a reduction or cessation of their tinnitus after implantation. However, 8.2% of the patients with tinnitus reported a postoperative deterioration of their tinnitus. In addition, among the patients without preoperative tinnitus, 19.6% reported the start of tinnitus after implantation. The self-reported change of tinnitus correlated with the pre- and postoperative scores on the THI and THQ. The THQ showed slightly more changes in scores after cochlear implantation compared to the THI. Overall hearing handicap and feelings of anxiety and depression decreased after implantation. In conclusion, tinnitus is reduced after cochlear implantation in an important part of the patients, but in a small part implantation has a negative effect on tinnitus. When tinnitus starts after implantation, the tinnitus handicap is mild.

“…The assumption is that the suppression of tinnitus will alleviate its intrusiveness and reduce overall burden. However, although the number of profoundly deaf patients reporting tinnitus decreases following implantation, clinical observations suggest that a large proportion of CI recipients still experience some degree of tinnitus-related handicap (Pan et al 2009;Bovo et al 2011;Kloostra et al 2015;Ramakers et al 2015). A review of studies that have assessed the levels of tinnitus-related handicap following implantation suggested that about 25% of CI users experience a clinically significant tinnitus, that is, a degree of tinnitus-related handicap that may warrant intervention (Baguley 2010).…”

Tinnitus and Sleep Difficulties After Cochlear Implantation

et al. 2016

Objectives: To estimate and compare the prevalence of and associations between tinnitus and sleep difficulties in a sample of UK adult cochlear implant users and those identified as potential candidates for cochlear implantation. Design:The study was conducted using the UK Biobank resource, a population-based cohort of 40-to 69-year olds. Self-report data on hearing, tinnitus, sleep difficulties, and demographic variables were collected from cochlear implant users (n = 194) and individuals identified as potential candidates for cochlear implantation (n = 211). These "candidates" were selected based on (i) impaired hearing sensitivity, inferred from self-reported hearing aid use and (ii) impaired hearing function, inferred from an inability to report words accurately at negative signal to noise ratios on an unaided closed-set test of speech perception. Data on tinnitus (presence, persistence, and related distress) and on sleep difficulties were analyzed using logistic regression models controlling for gender, age, deprivation, and neuroticism.Results: The prevalence of tinnitus was similar among implant users (50%) and candidates (52%; p = 0.39). However, implant users were less likely to report that their tinnitus was distressing at its worst (41%) compared with candidates (63%; p = 0.02). The logistic regression model suggested that this difference between the two groups could be explained by the fact that tinnitus was less persistent in implant users (46%) compared with candidates (72%; p < 0.001). Self-reported difficulties with sleep were similar among implant users (75%) and candidates (82%; p = 0.28), but participants with tinnitus were more likely to report sleep difficulties than those without (p < 0.001). The prevalence of sleep difficulties was not related to tinnitus persistence (p = 0.28) or the extent to which tinnitus was distressing (p = 0.55). Conclusions:The lack of association between tinnitus persistence and sleep difficulties is compatible with the notion that tinnitus is suppressed in implant users primarily during active electrical stimulation and may return when the implant is switched off at night time. This explanation is supported by the similar prevalence of sleep problems among implant users and potential candidates for cochlear implantation, despite differences between the groups in tinnitus persistence and related emotional distress. Cochlear implantation may therefore not be an appropriate intervention where the primary aim is to alleviate sleep difficulties.

“…Unfortunately, most studies to date have small numbers of subjects [Bovo et al, 2011]. Pooling the data of several studies is difficult because of the different criteria and different reporting used [Baguley and Atlas, 2007;Quaranta et al, 2004].…”

“…Pooling the data of several studies is difficult because of the different criteria and different reporting used [Baguley and Atlas, 2007;Quaranta et al, 2004]. Ideally, studies should report at least tinnitus loudness and distress due to tinnitus, as suggested by Bovo et al [2011].…”

Tinnitus before and 6 Months after Cochlear Implantation

et al. 2012

In this prospective multicenter study, tinnitus loudness and tinnitus-related distress were investigated in 174 cochlear implant (CI) candidates who underwent CI surgery at a Swiss cochlear implant center. All subjects participated in two session, one preoperatively and one 6 months after device activation. In both sessions, tinnitus loudness was assessed using a visual analogue scale and tinnitus distress using a standardized tinnitus questionnaire. The data were compared with unaided pre- and postoperative pure tone thresholds, and postoperative speech reception scores. 71.8% of the subjects reported tinnitus preoperatively. Six months after CI surgery 20.0% of these reported abolition of their tinnitus, 51.2% a subjective improvement, 21.6% no change and 7.2% a deterioration. Of the 49 (28.2%) subjects with no tinnitus preoperatively, 5 developed tinnitus 6 months after CI. These 5 had poorer speech understanding after CI surgery with their device than the group who remained tinnitus free. We found no correlation between tinnitus improvement, age, duration of tinnitus, or change in unaided hearing thresholds between the two sessions.
