Interaction of tinnitus suppression and hearing ability after cochlear implantation

To study the postoperative impact of cochlear implants (CIs) on tinnitus, as well as the impact of tinnitus on speech recognition with CI switched on | Acta Oto-Laryngologica 

Methods: Fifty-two postlingual deafened CI recipients (21 males and 31 females) were assessed using an established Tinnitus Characteristics Questionnaire and Tinnitus Handicap Inventory (THI) before and after cochlear implantation. The tinnitus loudness was investigated when CI was switched on and off in CI recipients with persistent tinnitus. The relation between tinnitus loudness and recipients’ satisfaction of cochlear implantation was analyzed by the visual analogue scale (VAS) score.

Results: With CI ‘OFF’, 42 CI recipients experienced tinnitus postimplant ipsilaterally and 44 contralaterally. Tinnitus was totally suppressed ipsilateral to the CI with CI ‘ON’ in 42.9%, partially suppressed in 42.9%, unchanged in 11.9% and aggravated in 2.4%. Tinnitus was totally suppressed contralaterally with CI ‘ON’ in 31.8% of CI recipients, partially suppressed in 47.7%, unchanged in 20.5%. Pearson correlation analysis showed that tinnitus loudness and the results of cochlear implant patients satisfaction was negatively correlated (r = .674, p < .001).

Conclusion: The study suggests six-month CI activation can be effective for suppressing tinnitus. The tinnitus loudness may affect patients’ satisfaction with the use of CI.

Coping with tinnitus

Having a chronic impairment can be stressful and can trigger multiple psychological reactions related to loss of functioning, physical discomfort, and unwanted change | Journal of Rehabilitation Research & Development

This narrative article on coping with tinnitus has four primary objectives.

  • First, theoretical perspectives about defining and categorizing coping are discussed.
  • Second, an overview of the empirical research on coping with tinnitus is provided, focusing on how coping with tinnitus has been measured and on the trends that were found in research on coping with tinnitus.
  • Third, the problems related to the current state of research on coping with tinnitus are highlighted.
  • Fourth, suggestions are provided on ways that researchers can improve research on coping with tinnitus.

Tinnitus Management

Whereas hearing aids have long been considered effective for providing relief from tinnitus, controlled clinical studies evaluating this premise have been very limited |  Journal of the American Academy of Audiology

Purpose: The purpose of this study was to systematically determine the relative efficacy of conventional receiver-in-the-canal hearing aids (HA), the same hearing aids with a sound generator (HA+SG), and extended-wear, deep fit hearing aids (EWHA), to provide relief from tinnitus through a randomized controlled trial. Each of these ear-level devices was a product of Phonak, LLC.

Results: There were 18 participants in each of the HA and EWHA groups and 19 in the HA+SG group. Gender, age, and baseline TFI severity were balanced across treatment groups. Nearly all participants had a reduction in tinnitus symptoms during the study. The average TFI change (improvement) from baseline was 21 points in the HA group, 31 points in the EWHA group, and 33 points in the HA+SG group. A “clinically significant” improvement in reaction to tinnitus (at least 13-point reduction in TFI score) was seen by 67% of HA, 82% of EWHA, and 79% of HA+SG participants. There were no statistically significant differences in the extent to which the devices reduced TFI scores. Likewise, the hearing-specific questionnaires and QuickSIN showed improvements following use of the hearing aids but these improvements did not differ across device groups.

Conclusions: There is insufficient evidence to conclude that any of these devices offers greater relief from tinnitus than any other one tested. However, all devices appear to offer some improvement in the functional effects of tinnitus.

Comparison of tinnitus and psychological aspects between the younger and older adult patients

Park, S.Y. et al. (2017) Auris Nasus Larynx. 44(2) pp. 147–151

Objective: To explore the differences in various tinnitus-related features and psychological aspects between the younger and older adult patients with tinnitus.

Conclusion: The older patients seemed to be more receptive to tinnitus. The majority of older tinnitus patients had concomitant hearing loss, and thus hearing rehabilitation should be considered preferentially for tinnitus management in this age group. Subjective tinnitus severity, depressive symptoms, and the stress levels were similar between the younger and older tinnitus patients. Therefore, treatment could be planned based upon the comprehensive understanding of the tinnitus characteristics and psychological aspects in each patient irrespective of age.

Mindfulness meditation versus relaxation therapy in the management of tinnitus.

Arif, M. et al. The Journal of Laryngology & Otology | Published online: 30 March 2017

Psychotherapeutic interventions have been adopted effectively in the management of tinnitus for a long time. This study compared mindfulness meditation and relaxation therapy for management of tinnitus.

This study suggests that although both mindfulness meditation and relaxation therapy are effective in the management of tinnitus, mindfulness meditation is superior to relaxation therapy.

To determine the pre- and post-operative prevalence of dizziness, tinnitus and taste disturbances in adult cochlear implant recipients.

The high prevalence of dizziness, tinnitus and taste disturbances reported by cochlear implant recipients necessitates that assessment of symptoms related to inner ear and chorda tympani damage are included when evaluating operative results.

Influence of well-known risk factors for hearing loss in a longitudinal twin study

Johnson, A-C. et al. (2017) International Journal of Audiology. 56(supp 1) pp.63-73

twins-1147613_960_720

Objective: The aim was to investigate the influence of environmental exposures on hearing loss in a twin cohort.

Conclusions: Pre-existing hearing loss can increase the risk of hearing impairment due to occupational noise exposure. An increased risk for NIHL was also seen in the group with exposures below 85 dB(A), a result that indicates awareness of NIHL should be raised even for those working in environments where sound levels are below 85 dB(A).
