Effectiveness of Tinnitan Duo® in Subjective Tinnitus with Emotional Affectation: A Prospective, Interventional Study.

To assess the effectiveness of a food supplement (Tinnitan Duo®) containing 5-hydroxytryptophan, Ginkgo biloba, magnesium, melatonin, vitamin B5 and B6, and zinc at improving tinnitus response and intensity. Prospective, single-center interventional study including patients with subjective tinnitus and emotional affectation. The primary endpoint was the change in the Tinnitus Handicap Inventory (THI) total score and the emotional subscale after 3 months of treatment. Secondary endpoints were the change from baseline to month 3 in (1) the Tinnitus Distress Rating (TDR) scale, and (2) in hearing status, and the safety profile of patients throughout the study. Sixty-one patients were included, and 29 completed the study. The THI total score was significantly reduced after 3 months of treatment in the per-protocol (PP, all the patients with no major protocol deviations) and intention-to-treat (ITT) populations (-15.7 and -7.5, respectively; p = 0.001). The emotional subscale score significantly decreased after 3 months of treatment by -5.6 in the PP (p = 0.001) and by -2.6 in the ITT populations (p = 0.001). Perceived tinnitus loudness significantly decreased after 3 months of treatment (p = 0.001). The audiogram showed no significant changes in hearing status after 3 months of treatment. Of the five adverse events (AEs) reported, all were mild or moderate, and three were related to the study treatment (two headaches and one dizziness). This new food supplement was associated with an improved tinnitus-related emotional affectation and with a good safety profile.

Binaural sound therapy for tinnitus treatment: A psychometric and neurophysiological evaluation.

INTRODUCTION: Tinnitus is an annoying buzz that manifests itself in many ways. In addition, it can provoke anxiety, stress, depression, and fatigue. The acoustic therapies have become the most commonly applied treatment for tinnitus, either self-administered or clinically prescribed. Binaural Sound Therapy (BST) and Music Therapy (MT) aim to reverse the neuroplasticity phenomenon related to tinnitus by adequately stimulating the auditory path-way. The goal of this research is to evaluate the feasibility of applying BST for tinnitus treatment by comparing its effect with MT effect. MATERIALS AND METHODS: 34 patients with tinnitus from 29 to 60 years were informed about the experimental procedure and consented their participation. Patients were divided into two groups: 1) MT and 2) BST. They applied their sound-based treatment for one hour every day along eight weeks. Each treatment was adjusted to Hearing Loss (HL) and tinnitus characteristics of each participant. To record EEG data, a bio-signal amplifier with sixteen EEG channels was used. The system recorded data at a sampling frequency of 256 Hz within a bandwidth between 0.1 and 100 Hz. RESULTS: The questionnaire-monitoring reported that MT increased tinnitus perception in 30% of the patients, and increased anxiety and stress in 8% of them. Regarding EEG-monitoring, major neural synchronicity over the frontal lobe was found after the treatment. In the case of BST reduced stress in 23% of patients. Additionally, BST reduced tinnitus perception similar to MT (15% of patients). With respect to EEG-monitoring, slightly major neural synchronicity over the right frontal lobe was found after the treatment. CONCLUSIONS: MT should be applied with caution since it could be worsening the tinnitus sufferer condition. On the other hand, BST is recommended for tinnitus sufferers who have side effects concerning stress but no anxiety.

Hearing more to hear less: a scoping review of hearing aids for tinnitus relief.

OBJECTIVE: As tinnitus is often associated with hearing loss, hearing aids have been proposed for tinnitus relief in literature for more than 70 years. There is a need for recent literature to be reviewed and guide decision making in tinnitus management. This scoping review aims to provide an update of the available evidence on hearing aids for tinnitus, focussing on the effect of sound amplification or combination devices (i.e. amplification and sound generation within one device). DESIGN: Research studies were included if they investigated hearing aids or combination devices for tinnitus and were published after 2011. STUDY SAMPLE: A total of 28 primary research studies were selected. RESULTS: Positive results of hearing aids in tinnitus patients were shown in 68% of the studies, whereas 14% demonstrated no change in tinnitus distress. However, the quality of the evidence across studies was variable. CONCLUSIONS: Scientific support for hearing aids and combination devices for tinnitus relief was found. The standalone effect of sound amplification and the added value of sound generators and adjustment of sound processing strategies needs further investigation. Stronger methodology in future studies is needed to reach consensus on how to optimise hearing solutions in a multidisciplinary approach.

Management of Tinnitus In Covid-19 Outbreak- A Comparative Study Between Mindfulness Based Tinnitus Stress Reduction And Tinnitus Retraining Therapy.

BACKGROUND: Covid-19 pandemic has caused a profound impact on the lives of people and has given rise to many mental health issues like anxiety and stress which eventually has given rise to bothersome tinnitus. In case of people having pre-existing tinnitus, the pandemic has raised the problem of tinnitus and the co-morbid issues related to tinnitus and severely affected the overall quality of life. Hence, we need to find a mean for home-based management of tinnitus and its associated problems. OBJECTIVE: To understand the mechanism of mental health and to compare between the mindfulness-based tinnitus reduction and tinnitus retraining therapy on android-based application. DESIGN: Comparative and Experimental design. METHOD: The study was conducted on 60 participants and was divided into two groups. Detailed audiological assessment, tinnitus assessment and Tinnitus Handicap Inventory (THI) and Tinnitus Cognitions Questionnaire (TCQ) were administered. Group-I was provided with tinnitus retraining therapy and group-II was provided with mindfulness based tinnitus stress reduction. After the post therapy evaluation the data were compiled for statistical analysis in SPSS software 20.0. Results: It was found that there were significant difference between the pre and post therapy scores of TRT and MBTSR in both THI and TCQ (p<0.001). CONCLUSION: Home-based management of tinnitus during the COVID-19 pandemic using both TRT and MBTSR were highly successful and had similar results MBTSR was found to be more useful as it had better outcome in reducing the tinnitus related annoyance and shown better improvement in QOL examination.

Risk of early-onset dementia among persons with tinnitus: a retrospective case-control study.

Higher rates of poor cognitive performance are known to prevail among persons with tinnitus in all age groups. However, no study has explored the association between tinnitus and early-onset dementia. We hypothesize that tinnitus may precede or occur concurrently with subclinical or early onset dementia in adults younger than 65 years of age. This case-control study used data from the Taiwan National Health Insurance Research Database, identifying 1308 patients with early-onset dementia (dementia diagnosed before 65 years of age) and 1308 matched controls. We used multivariable logistic regressions to estimate odds ratios (ORs) for prior tinnitus among patients with dementia versus controls. Among total 2616 sample participants, the prevalence of prior tinnitus was 18%, 21.5% among cases and 14.5% among controls (p < 0.001). Multivariable logistic regression showed and adjusted OR for prior tinnitus of 1.6 for cases versus controls (95% CI: 1.3 ~ 2.0). After adjusting for sociodemographic characteristics and medical co-morbidities, patients with early-onset dementia had a 67% higher likelihood of having prior tinnitus (OR = 1.628; 95% CI = 1.321-2.006). Our findings showed that pre-existing tinnitus was associated with a 68% increased risk of developing early-onset dementia among young and middle-aged adults. The results call for greater awareness of tinnitus as a potential harbinger of future dementia in this population.

Modulation of hyperacusis and tinnitus loudness in tinnitus patients with and without hearing loss following 3 weeks of acoustic stimulation: A proof-of-concept study.

Tinnitus and hyperacusis are two debilitating conditions that are highly comorbid. It has been postulated that they may originate from similar pathophysiological mechanisms such as an increase in central gain. Interestingly, sound stimulation has been shown to reduce central gain and is currently used for the treatment of both conditions. This study investigates the effect of sound stimulation on both tinnitus and hyperacusis in the same patients. Two distinct series of tinnitus participants were tested: one with normal or near-normal hearing (n=16) and one with hearing loss (n=14). A broadband noise shaped to cover most of the tinnitus frequency spectrum was delivered through hearing aids using the noise generator feature (no amplification) and verified through real-ear measurements. Participants received sound stimulation for 3 weeks and were tested before (at baseline), then after 1 week and at the end of the 3 weeks of sound stimulation. There was also a 1-month follow-up after the end of the stimulation protocol. The measurements included self-reported measures of tinnitus and hyperacusis (VAS), validated questionnaires (THI, HQ) and psychoacoustic measurements (tinnitus battery and loudness functions). On both self-assessment (VAS of sound tolerance and tinnitus loudness) and psychoacoustic measures (loudness function and tinnitus loudness in dB), about 50% of tinnitus participants had a synchronous (either a decrease or an increase) modulation of hyperacusis and tinnitus loudness after 1 week and 3 weeks of acoustic stimulation and up to about 70% of participants at 1-M follow-up. The decrease of hyperacusis and tinnitus loudness was more prevalent in normal-hearing participants. There was a significant increase in tinnitus loudness during and following the stimulation in the group with hearing loss. Hyperacusis improvement as assessed by loudness function was significantly correlated with the intensity level of the acoustic stimulation (dB level of the noise produced by the noise generator) in tinnitus participants with normal/near-normal hearing thresholds. Our study partly supports the central gain hypothesis by showing synchronous modulation of hyperacusis and tinnitus loudness. It also shows beneficial effects of acoustic stimulation in some tinnitus individuals, in particular those with normal or near-normal hearing, while highlighting the importance of a careful fitting of sound generators to prevent increase. Since the amplification feature was not turned on in our study, future work should determine whether amplification alone, or in addition to acoustic stimulation (sound generators), would benefit to those with hearing loss.

Macrostructural Changes of the Acoustic Radiation in Humans with Hearing Loss and Tinnitus Revealed with Fixel-Based Analysis.

Age-related hearing loss is the most prevalent sensory impairment in the older adult population and is related to noise-induced damage or age-related deterioration of the peripheral auditory system. Hearing loss may affect the central auditory pathway in the brain, which is a continuation of the peripheral auditory system located in the ear. A debilitating symptom that frequently co-occurs with hearing loss is tinnitus. Strikingly, investigations into the impact of acquired hearing loss, with and without tinnitus, on the human central auditory pathway are sparse. This study used diffusion-weighted imaging (DWI) to investigate changes in the largest central auditory tract, the acoustic radiation, related to hearing loss and tinnitus. Participants with hearing loss, with and without tinnitus, and a control group were included. Both conventional diffusion tensor analysis and higher-order fixel-based analysis were applied. The fixel-based analysis was used as a novel framework providing insight into the axonal density and macrostructural morphologic changes of the acoustic radiation in hearing loss and tinnitus. The results show tinnitus-related atrophy of the left acoustic radiation near the medial geniculate body. This finding may reflect a decrease in myelination of the auditory pathway, instigated by more profound peripheral deafferentation or reflecting a preexisting marker of tinnitus vulnerability. Furthermore, age was negatively correlated with the axonal density in the bilateral acoustic radiation. This loss of fiber density with age may contribute to poorer speech understanding observed in older adults.SIGNIFICANCE STATEMENT Age-related hearing loss is the most prevalent sensory impairment in the older adult population. Older individuals are subject to the cumulative effects of aging and noise exposure on the auditory system. A debilitating symptom that frequently co-occurs with hearing loss is tinnitus: the perception of a phantom sound. In this large DWI-study, we provide evidence that in hearing loss, the additional presence of tinnitus is related to degradation of the acoustic radiation. Additionally, older age was related to axonal loss in the acoustic radiation. It appears that older adults have the aggravating circumstances of age, hearing loss, and tinnitus on central auditory processing, which may partly be because of the observed deterioration of the acoustic radiation with age.

Effective sound therapy using a hearing aid and educational counseling in patients with chronic tinnitus.

OBJECTIVE: This study aimed to assess the effectiveness of our sound therapy with appropriate hearing aid fitting and periodic hearing aid adjustment in patients with chronic tinnitus. METHODS: We conducted a retrospective study. The study included 490 individuals who received treatment with hearing aids for chronic tinnitus at least for 3 months. To determine the effects of tinnitus on patients' quality of life, the participants completed a series of questionnaires, including the Tinnitus Handicap Inventory (THI), Visual Analogue Scale (VAS) for loudness and annoyance, and questionnaires of subjective symptom improvement. Data were collected at entry and 3 months and 1 year after treatment initiation. RESULTS: All 490 participants completed the questionnaires at 3 months; however, only 312 completed them at 1 year. The mean ± standard deviation THI score before treatment decreased significantly at 3 months (490 participants: 53 ± 25 to 11 ± 16 and 312 participants: 55 ± 24 to 12 ± 16) and 1 year (55 ± 24 to 9 ± 14) (P < 0.01). The mean VAS score for tinnitus loudness before treatment decreased significantly at 3 months (490 participants: 70 ± 22 to 25 ± 27 and 312 participants: 71 ± 22 to 27 ± 26) and 1 year (71 ± 22 to 21 ± 28) (P < 0.01). In addition, the mean VAS score for tinnitus annoyance before treatment decreased significantly at 3 months (490 participants: 75 ± 26 to 20 ± 26 and 312 participants: 75 ± 25 to 23 ± 27) and 1 year (75 ± 25 to 17 ± 26) (P < 0.01). Approximately 80% of patients noticed improvements in their tinnitus annoyance and loudness, as determined by their responses to the questionnaires of subjective symptom improvement. CONCLUSION: The results of this study suggest that treatment with sound therapy may ameliorate the symptoms of chronic tinnitus associated with hearing loss.

Interpreting auditory brainstem evoked responses and distortion product otoacoustic emissions in diabetic patients with normal hearing.

OBJECTIVE: Hearing impairment is a reported late complication of diabetes mellitus (DM). Previous studies have suggested that microangiopathic complications may cause cochlear nerve function deterioration. We evaluated the auditory brainstem evoked responses (ABRs) and distortion product otoacoustic emission (DPOAE) results according to the presence of DM in subjects with normal hearing. METHODS: A cross-sectional comparative study was conducted from January 2016 to January 2018. Auditory function tests including ABR and DPOAE were performed for outpatients complaining of unilateral tinnitus. All of analyses were conducted in ears without tinnitus on contralateral side of tinnitus ears. We included subjects showing hearing thresholds within 25 dB at 0.5, 1k, 2k, and 4k on pure tone audiometry. 45 ears in patients with type 2 diabetes mellitus and 85 ears in non-diabetic patients were finally enrolled in our study. RESULTS: Diabetic subjects showed significantly more prolonged absolute peak latencies (I, III, V) and inter-peak latencies (I-V, III-V) than non-diabetic subjects. However, there was no significant difference in the inter-peak latency (I-III) between these two groups. Diabetic subjects also showed significantly lower amplitudes at f2 frequencies of 1001, 1200, 1587, 4004, 5042, and 6348 Hz than non-diabetic subjects. Additionally, the prevalence of a DPOAE response, defined as 3 dB above the noise floor, was significantly lower in diabetic subjects than that in non-diabetic subjects. CONCLUSION: Diabetic patients with normal hearing can still have abnormal ABR and DPOAE results due to diabetic neuroangiopathy. ABR and DPOAE assessments can help in detecting subclinical auditory dysfunction, which precedes the manifestation of hearing impairment in diabetic patients.

Individualized Treatment of Tinnitus during Sleep Using Combined Tinnitus Signal and Music.

INTRODUCTION: Tinnitus is a widely seen otological symptom that interferes with daily activities and causes discomfort. Tinnitus treatments can be classified into 4 main groups: pharmacological treatments, cognitive and behavioral therapy, psychological treatments, and combined treatment approaches made up of at least 2 of these 3 treatment methods. OBJECTIVE: The aim of this study was to assess whether it would be possible to develop an individualized treatment method of tinnitus by application of a combined tinnitus signal and music during sleep. METHODS: Forty-three ears of 30 patients who had subjective tinnitus were included. The patients were evaluated using Tinnitus Handicap Inventory, Visual Analogue Scale, and Beck Depression Inventory. The psychoacoustic parameters of tinnitus, such as tinnitus frequency and loudness, and minimal masking levels, were determined. The patients were asked to select musical melodies that they liked. The tinnitus frequency of each patient was taken as the central frequency according to ANSI 2004. All sound files were prepared as stereo channels, with 16-bit resolution and 44,100 Hz sampling rate. The root mean square power value of the music and the band noise's average root mean square power value were equalized with the "Amplification" command, and 70% of the music and 30% of wide/narrow-band noise were mixed as a stereo channel by the "Mix Paste" command. The patients were instructed to listen to that individualized music/narrow-band noise (tinnitus signal) for 2 h during sleep for a duration of 6 months. RESULTS: Tinnitus frequencies of the patients measured prior to treatment and at the second, fourth, and sixth months of follow-up were not significantly different. A statistically significant decrease was seen in tinnitus loudness, minimal masking levels, and residual inhibition during the follow-up. Tinnitus Handicap Inventory scores decreased significantly during follow-up, and the number of patients who complained of tinnitus decreased (p < 0.05). The Visual Analogue Scale scores significantly decreased during follow-up (p < 0.05). Beck Depression Inventory scores decreased significantly during follow-up (p < 0.05). CONCLUSION: Stimulation of the auditory and limbic systems during sleep by the tinnitus signal combined with individualized musical melodies seems an alternative, effective, and cheap method in the treatment of tinnitus.

Broadband Sound Equalized by The Hearing Loss Curves as an Improved Stimulus for Tinnitus Retraining Therapy-A Pilot, Non-Controlled Observational Study.

OBJECTIVES: This study aimed to assess if a short tinnitus treatment, combining counseling with broadband noise filtered by the hearing loss curves, provided significant relief in tinnitus patients. MATERIALS AND METHODS: 25 tinnitus subjects of heterogeneous etiology were subjected to sound therapy, 1 hour per day, for 4 months. All of them underwent a unique initial counseling session aimed at undoing previous negative perceptions of tinnitus and highlighting the real expectations from tinnitus therapies. Customized stereo sound stimuli were designed by filtering broadband noise using the hearing loss curves of each ear. A monthly follow-up was carried out by assessing the severity of tinnitus through a validated Spanish version of the Tinnitus Handicap Inventory (THI). RESULTS: 88% (22 of 25) of the patients completing the treatment obtained significant relief after 4 months. After 4 months of treatment, the average decrease in THI from its initial value for the 22 successful participants was 29. CONCLUSION: The average THI score reduction after 4 months of treatment can be considered to be an excellent improvement when compared with other similar studies. The proposed customized sound therapy was effective in reducing tinnitus in patients of heterogeneous etiology.

Current Validated Medical Treatments for Tinnitus: Cognitive Behavioral Therapy.

Tinnitus distress results from a weave of physical and psychological processes. Reducing the power of the psychological processes will therefore reduce the degree of suffering. The main psychological therapy in this context is cognitive behavioral therapy (CBT). This seeks to understand and change the influence of thinking processes, including information processing biases, and the behaviors that these motivate, on the experience of tinnitus. The results of systematic reviews and meta-analyses indicate that CBT is the tinnitus management approach for which there is the most robust evidence. In spite of this, it remains difficult to access for people with tinnitus.

Autopercepção do zumbido: estudo pré e pós-adaptação de próteses auditivas / Self-perception of tinnitus: study before and after adaptation of hearing aids

RESUMO Objetivo Verificar benefícios do uso de próteses auditivas na autopercepção do zumbido em adultos e idosos sem experiência prévia de amplificação. Métodos O estudo incluiu indivíduos de ambos os sexos, com queixa de zumbido, acompanhados em hospital público. Aplicaram-se os seguintes exames e instrumentos para mensurar o zumbido e determinar o seu incômodo: pesquisa do pitch e loudness, Escala Visual Analógica (EVA), pesquisa do nível mínimo de mascaramento, inibição residual e Tinnitus Handicap Inventory (THI). As avaliações foram realizadas em duas etapas: antes da adaptação das próteses auditivas e após um mês de uso dos aparelhos. Resultados Dos 20 indivíduos participantes, 60% eram idosos. Verificou-se diferença na autopercepção do zumbido pré e pós-protetização, medido pelas escalas THI e EVA. Também se observaram diferenças nas medidas psicoacústicas, com exceção do pitch, antes e após a amplificação. Além disso, houve correlação entre o tempo de zumbido e a idade com os escores finais do THI. Conclusão O uso de próteses auditivas reduziu o incômodo provocado pelo zumbido, com alteração nas medidas psicoaústicas e no impacto na qualidade de vida.

ABSTRACT Purpose To verify the benefits of using hearing aids in self-perception of tinnitus in adults and elderly without previous experience of amplification. Methods The study included individuals of both gender, with tinnitus complaint, accompanied in public hospital. The following tests and instruments were used to measure tinnitus and determine its discomfort: pitch and loudness, Visual Analogue Scale (VAS), minimum masking level, residual inhibition and Tinnitus Handicap Inventory (THI). The evaluations were performed in two stages: before the adaptation of the hearing aids and after one month of use of the devices. Results Of the 20 participants, 60% were elderly. There was a difference in self-perception of tinnitus before and after hearing aid fitting, as measured by THI and VAS. Differences in psychoacoustic measures were also observed, with the exception of pitch, before and after amplification. In addition, there was a correlation between tinnitus time and age with final THI scores. Conclusion The use of hearing aids was determined to reduce the annoyance caused by tinnitus, with changes in psycho-acoustic measures and impact on quality of life.

Effects of oral zinc supplementation on patients with noise-induced hearing loss associated tinnitus: A clinical trial.

BACKGROUND: Zinc plays a vital antioxidant role in human metabolism. Recent studies have demonstrated a correlation between noise-induced hearing loss (NIHL) and oxidative injury; however, no investigation has focused specifically on the subgroup of NIHL associated tinnitus patients. We aimed to evaluate the effectiveness of zinc supplementation in treating NIHL associated tinnitus. METHODS: Twenty patients with tinnitus and a typical NIHL audiogram (38 ears) were included in this study. Another 20 healthy subjects were used as the control group. A full medical history assessment was performed, and each subject underwent an otoscopic examination, basic audiologic evaluation, distortion product otoacoustic emissions (DPOAEs), tinnitus-match testing, Tinnitus Handicap Inventory (THI) and serum zinc level analyses. After 2 months of treatment with zinc, all tests were repeated. RESULTS: There was a significant difference between pretreatment and post-treatment within the tinnitus group (73.6 vs. 84.6 µg/dl). The pre- and post-treatment difference in serum zinc was significantly higher in the young group (≦50 years) compared to the old group (19.4 ± 11.4 vs. 2.6 ± 9.2 µg/dl, respectively; p = 0.002). There were no statistically significant differences in hearing thresholds, speech reception thresholds, or tinnitus frequency and loudness results before and after treatment. In addition, 17 patients (85%) showed statistically significant improvement of THI-total scores post-treatment, from 38.3 to 30 (p = 0.024). CONCLUSIONS: Zinc oral supplementation elevated serum zinc levels, especially in younger patients. THI scores improved significantly following zinc treatment in patients with NIHL associated tinnitus. However, no improvements in objective hearing parameters were observed.

Living with tinnitus and the health care journey: An interpretative phenomenological analysis.

OBJECTIVES: Tinnitus is a very common experience, and although usually mild, in a significant proportion of people, it is intrusive, persistent, and disabling. This paper explores the lived experience of chronic disabling tinnitus, with the aim of understanding how distress and chronicity occur, and what might help to reduce this. DESIGN: Nine individuals were interviewed 6 months after completing mindfulness-based cognitive therapy (MBCT) as part of a randomized controlled trial. The results reported here focus on their experiences of tinnitus before receiving MBCT. METHODS: Data were collected through semi-structured, face-to-face interviews with a clinical psychologist, and an interpretative phenomenological analysis approach was used. RESULTS: Two supraordinate themes emerged. 'Living with tinnitus' describes a range of significant and profound life changes that result from the condition. Tinnitus can be a life-altering condition affecting thoughts, emotions, attention, behaviour, and the social world. 'The health care journey' shows how chronic distress was intensified by unhelpful health communications and alleviated by helpful consultations. CONCLUSIONS: Tinnitus is a biopsychosocial condition, and associated distress is affected by cognitive, behavioural, attentional, and social factors. The individuals' initial reactions to tinnitus interact with the responses of others, including health care professionals. The burden of tinnitus could be reduced by developing early interventions that offer clear, helpful, and realistic information about tinnitus and appropriate treatments. Statement of contribution What is already known on this subject? Tinnitus is the experience of an internal sound without an external sound source. It can be troubling, disabling, and chronic and usually has no clear medical cause or medical treatment, but psychological interventions are promising. Cognitive, behavioural, and attentional factors play a role in distress and therapeutic outcome. Clinical encounters are improved by aligning patient and clinician and sharing decision-making. What does this study add? It is the first in-depth study exploring how tinnitus distress and health care systems interact. It shows how a biopsychosocial approach to tinnitus may reduce tinnitus burden more effectively than a biomedical, diagnostic-focused approach. It indicates how effective early health care information could be used to reduce chronic tinnitus distress.

Telephone-Based Progressive Tinnitus Management for Persons With and Without Traumatic Brain Injury: A Randomized Controlled Trial.

OBJECTIVES: This randomized controlled trial evaluated the efficacy of delivering coping skills education from Progressive Tinnitus Management (PTM) by telephone (Tele-PTM). The trial followed a previous pilot study that showed positive results for Tele-PTM. DESIGN: Participants included individuals with bothersome tinnitus (N = 205) located anywhere within the United States. A special emphasis was given to including individuals who had experienced one or more traumatic brain injuries (TBIs). Participants were randomized to either Tele-PTM intervention or 6-month wait-list control (WLC). The Tele-PTM intervention involved five telephone appointments-two led by an audiologist (teaching how to use therapeutic sound) and three by a psychologist (teaching coping skills derived from cognitive-behavioral therapy). It was hypothesized that Tele-PTM would be more effective than WLC in reducing functional effects of tinnitus as measured with the Tinnitus Functional Index. Additional outcome measures included the Self-Efficacy for Managing Reactions to Tinnitus questionnaire and the Hospital Anxiety and Depression Scale. The effect of Tele-PTM on outcomes was estimated using linear mixed models. RESULTS: Overall results showed convincingly that the Tele-PTM group had significantly better outcomes than the WLC group. These results were consistent across all outcome measures, indicating not only a reduction of tinnitus functional distress but also increased self-efficacy. Improvements in measures of anxiety and depression were also observed. Tele-PTM participants in all TBI categories showed significant improvement. CONCLUSIONS: Results provide strong support for use of Tele-PTM methodology for persons with bothersome tinnitus, regardless of whether the person also has TBI symptoms. The effect size for Tele-PTM was high for the primary outcome measure, the Tinnitus Functional Index, and all other outcome measures showed significant improvement. Combined with our previous pilot study, the Tele-PTM method is validated for potential nationwide provision of tinnitus services.

Psychoacoustic classification of persistent tinnitus / Classificação psicoacústica do zumbido persistente

Abstract Introduction: Tinnitus is a difficult to treat symptom, with different responses in patients. It is classified in different ways, according to its origin and associated diseases. Objective: to propose a single and measurable classification of persistent tinnitus, through its perception as sounds of nature or of daily life and its comparison with pure tone or noise, of high or low pitch, presented to the patient by audiometer sound. Methods: A total of 110 adult patients, of both genders, treated at the Tinnitus Outpatient Clinic, were enrolled according to the inclusion and exclusion criteria. Otorhinolaryngologic and Audiological, Pitch Matching and Loudness, Visual Analog Scale, Tinnitus Handicap Inventory and Minimum Masking Level assessments were performed. Results: In these 110 patients, 181 tinnitus complaints were identified accordingly to type and ear, with 93 (51%) Pure Tone, and 88 (49%) Noise type; 19 at low and 162 at high frequency; with a mean in the Pure Tone of 5.4.07 in the Visual Analog Scale and 12.31 decibel in the Loudness and a mean in the Noise of 6.66 and 10.51 decibel. For Tinnitus Handicap Inventory and Minimum Masking Level, the 110 patients were separated into three groups with tinnitus, Pure Tone, Noise and multiple. Tinnitus Handicap Inventory higher in the group with multiple tinnitus, of 61.38. Masking noises such as White Noise and Narrow Band were used for the Minimum Masking Level at the frequencies of 500 and 6000 Hz. There was a similarity between the Pure Tone and Multiple groups. In the Noise group, different responses were found when Narrow Band was used at low frequency. Conclusion: Classifying persistent tinnitus as pure tone or noise, present in high or low frequency and establishing its different characteristics allow us to know its peculiarities and the effects of this symptom in patients' lives.

Resultados: Nesses 110 pacientes foram identificadas 181 queixas de zumbido separadas por tipo e orelha, 93 (51%) tipo tom puro e 88 (49%) tipo ruído 19 de baixa frequência e 162 de alta frequência; com média do Visual Analog Scale no tom puro de 5,47 e ruído de 6,66; média do Loudness do tom puro de 12,31 dBNS e ruído de 10,51 dBNS. Para o Tinnitus Handicap Inventory e o Minimum Masking Level os 110 pacientes foram separados em três grupos com zumbido, tom puro, ruído e múltiplo, com a média do Tinnitus Handicap Inventory maior no grupo com zumbido múltiplo com 61,38. Para o Minimum Masking Level foram usados os ruídos mascaradores tipo White Noise e Narrow Band nas frequências de 500 Hz e 6000 Hz. Houve semelhança entre os grupos com tom puro e múltiplo. No grupo de ruído foram encontradas respostas diferentes quando usado o Narrow Band em frequência baixa. Conclusão: Classificar o zumbido persistente em tom puro ou ruído, presentes em frequência alta ou baixa e estabelecer suas diferentes características nos permitem conhecer suas particularidades e a repercussão desse sintoma na vida dos pacientes.

Electric-acoustic stimulation suppresses tinnitus in a subject with high-frequency single-sided deafness.

BACKGROUND: A suggested solution to suppress tinnitus is to restore the normal sensory input. This is based on the auditory deprivation hypothesis. It is known that hearing aids can provide sufficient activation of the auditory nervous system and reduce tinnitus in subjects with mild to moderate hearing loss and that cochlear implantation can reduce tinnitus in subjects with severe to profound hearing loss. This applies to subjects with single-sided deafness (SSD) or bilateral hearing loss. AIM: To investigate if electric-acoustic stimulation (EAS) can reduce severe tinnitus in a subject with residual hearing in the ipsilateral ear and contralateral normal hearing (high-frequency SSD) by restoring the auditory input. METHODS: Tinnitus reduction was investigated for 1 year after implantation in a subject with high-frequency SSD, who uses EAS, and was compared to 11 subjects with a cochlear implant (CI) with SSD. The Visual Analogue Scale (VAS) and the Tinnitus Questionnaire (TQ) were administered pre-operatively and at 1, 3, 6, and 12 months after implantation. RESULTS: Significant tinnitus reduction was observed 1 month after implantation on the VAS in the subjects with SSD using a CI. Tinnitus reduction was also observed in the subject with high-frequency SSD using EAS. A further decrease was observed 3 months after implantation. The TQ and VAS scores remained stable up to 1 year after implantation. CONCLUSION: A CI can significantly reduce ipsilateral severe tinnitus in a subject with SSD. Ipsilateral severe tinnitus can also be reduced using EAS in subjects with high-frequency SSD.

Cathodal neuromodulation of dominant temporoparietal cortex with transcranial direct current stimulation for tinnitus: A case series.

There is scant literature on the effectiveness of using transcranial direct current stimulation (tDCS) as an intervention modality for managing tinnitus. The current case series reflects the use of tDCS as an effective intervention for tinnitus while inhibiting the dominant temporoparietal cortex and simultaneous stimulating the non-dominant dorsolateral prefrontal cortex.

Effects of tinnitus treatments on sleep disorders in patients with tinnitus.

OBJECTIVE: To assess the effects of tinnitus treatments on sleep disorders in patients with tinnitus. DESIGN: Subjects completed the Pittsburg Sleep Quality Index (PSQI), Tinnitus Handicap Inventory (THI), Self-rating Depression Scale (SDS), and State Trait Anxiety Inventory (STAI). The questionnaire results and the patients' sex, age, time since the onset of tinnitus, and mean hearing level were examined, and differences between a sleep disorder group and a normal sleep group were examined. Patients completed the questionnaires again after initiating tinnitus treatments (counselling and use of sound generators), and the change in questionnaire scores at follow-up was evaluated. STUDY SAMPLE: Patients (N = 100) with tinnitus who visited Keio University Hospital and started treatment without medication between 2005 and 2008. RESULTS: Sixty-six percent of the patients had sleep disorders. Compared with patients without sleep disorders, patients with sleep disorders had significantly higher SDS and STAI scores at the first visit. The mean PSQI scores showed significant improvement at follow-up. CONCLUSIONS: Sleep disorders in patients with tinnitus improved after tinnitus treatments. Complex interactions between depressive symptoms and anxiety may occur in these patients. The improvement in sleep disorders at follow-up was correlated with improvements in tinnitus severity and state anxiety.
