“…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]. Other remarkable effects of unilateral cochlear implantation are the reduction of tinnitus in the contralateral ear and the existence of residual inhibition of tinnitus after switching off the cochlear implant [Baguley and Atlas, 2007;Quaranta et al, 2008].…”

“…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].

“…Previous studies have described a prevalence of tinnitus in cochlear implant candidates ranging from 63 to 100%, with a mean prevalence of 80% [Baguley and Atlas, 2007;Quaranta et al, 2008;Kompis et al, 2012;Kim et al, 2013].…”

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.

“…Because our patients were deaf before the CI surgery, changes in frequency and intensity of tinnitus could not be evaluated. Some previous studies used validated questionnaires to assess the tinnitus handicap in the implanted patients [Andersson et al, 2009;Miyamoto et al, 1997;Pan et al, 2009;Quaranta et al, 2008;Souliere Jr. et al, 1992]. However, data regarding tinnitus impairment before and after CI often include general information: better, no change or worse [Mo et al, 2002;Tyler, 1994].…”

The Impact of Cochlear Implantation on Tinnitus, Stress and Quality of Life in Postlingually Deafened Patients

et al. 2011

Tinnitus is a common complaint in the candidates for cochlear implantation (CI). Tinnitus-related distress has often been measured in these patients using categorical ratings, which lack information about tinnitus severity, stress and health-related quality of life or their correlation. Here, using 4 validated questionnaires, we evaluated psychometric parameters and the quality of life of 32 postlingually deafened patients before and after CI. The data regarding pre-CI were collected retrospectively. Of all patients included in this study, 28 (87.5%) suffered from tinnitus before implantation. Following a mean of 24 months after surgery, these patients reported a significant decrease (39.2%) of tinnitus impairment, as measured by the Tinnitus Questionnaire. In none of the 28 patients has tinnitus worsened. Moreover, the 4 tinnitus-free patients remained so after the CI surgery. In addition, the implant supply resulted in 36.7% reduction in perceived stress and in 15.4% reduction in evasive coping. In addition, the focus on positive coping has improved by 12.3%, whereas the health-related quality of life improved by 53.4% in all patients. Tinnitus impairment and stress were reduced more strongly in patients who had initially higher scores. Interestingly, a significant correlation between the psychometric scores was found mainly after CI. Our results indicate that patients with higher tinnitus-related distress have a lower quality of life, lesser coping abilities and perceive more stress, but before implantation it is masked by deafness. We conclude that tinnitus-related screening of patients before and after CI is an important step in the identification of individuals who would benefit from specific fitting and/or tinnitus therapy after implantation.
