Auditory discrimination training for tinnitus treatment: the effect of different paradigms

Acoustic deprivation, i.e. hearing loss, is responsible for a cascade of processes resulting in reorganisation of the cortex. Tinnitus mechanisms are explained by synchronization of the neural spontaneous activity and might be related to cortical re-mapping. Auditory discrimination training (ADT) has demonstrated in both animals and humans to induce tonotopical changes in the auditory pathways through neural plasticity. We hypothesize that ADT could have some effect on tinnitus perception. The objective of this study is to compare the effect on tinnitus following two paradigms of ADT. Only patients from 20 to 60 years of age were recruited. Inclusion criteria were pure tone tinnitus of mild or moderate handicap according to the Tinnitus Handicap Inventory score (<56). ADT patients were randomized in two groups: SAME (ADT in the same frequency of tinnitus pitch, 20 patients) and NONSAME (ADT in the frequency one-octave below tinnitus pitch, 21 patients). Groups of pair of tones (70% standard tones ST, 30% deviant tones ST + 0.1–0.5 kHz) were randomly mixed for 20 min/day during 1 month. Patient had to mark when the two sounds of the pair were similar or different. Control group included 26 patients from the waiting list (WLG). Patients were also divided according to the trained frequency and the deepest hearing-impaired frequency. Outcome parameters were set up according to the answer to the question “is your tinnitus better, same, or worse with the treatment?” (RESP), the tinnitus handicap inventory (THI) and the visual analogue scale from 1 to 10 on tinnitus intensity (VAS). Tinnitus improved in 42.2% of the patients (RESP). VAS and THI scores were reduced but only THI differences were statistically significant (P = 0.003). ADT patients improved significantly compared with WLG in RESP and THI scores (P < 0.01). Training frequencies one-octave below the tinnitus pitch (NONSAME) decreased significantly THI scores compared with patients trained frequencies similar to tinnitus pitch (SAME, P = 0.035). RESP and VAS scores decreased more in NONSAME group though differences were not significant. We did not find any differences when comparing the group training the deepest hearing-impaired frequency and the group who trained other frequencies. Auditory discrimination training significantly improved tinnitus handicap compared to a waiting list group. Those patients who trained frequencies one octave below the tinnitus pitch had better outcome than those who performed the ADT with frequencies similar to the tinnitus pitch (P = 0.035)

Relationships among speech perception, self-rated tinnitus loudness and disability in tinnitus patients with normal pure-tone thresholds of hearing

Exactly how speech perception and tinnitus perception are related remains unclear. This study investigated how tinnitus alone affects speech perception and the relationship between speech perception, tinnitus loudness, and tinnitus disability. The Mandarin Speech Perception in Noise Test (MSPIN), Tinnitus Loudness Scaling (TLS), and Tinnitus Handicap Inventory (THI) were utilized to assess 20 tinnitus patients with normal hearing. The tinnitus group had a significantly lower MSPIN score than the control group (p < 0.01). TLS and THI scores were strongly correlated (r(2): 0.534 approximately 0.627, p < 0.05). Correlations between MSPIN and TLS or THI scores were not significant. Tinnitus loudness correlated well with tinnitus-related disability. Neither tinnitus loudness nor disability was strongly correlated with speech perception. In noisy environments, tinnitus sufferers had significantly poorer ability to recognize speech than control subjects.     

Tinnitus in patients with profound hearing loss and the effect of cochlear implantation

The objectives of this study were to characterize the features of tinnitus in patients with profound sensorineural hearing loss and to evaluate the effect of cochlear implantation (CI) on their tinnitus. Medical records were reviewed for 35 patients who underwent CI, and completed tinnitus questionnaire between March 2003 and August 2011. Of them, 22 had tinnitus prior to CI (62.9 %) and the tinnitus group was older than the non-tinnitus group (47.5 ± 15.1 vs. 28.9 ± 15.2). The mean tinnitus handicap inventory (THI) score of the tinnitus group was 50.5 ± 28.7 before surgery, and the mean THI score and visual analogue scale (VAS) scores for loudness, annoyance, effect on life, and awareness decreased significantly after CI, with a mean follow-up period of 10.7 months. Tinnitus was completely eliminated in ten patients (45.5 %) and THI scores decreased in all patients. In a correlation analysis of the decrease in THI scores, preoperative VAS scores for loudness, awareness, effect on life, and annoyance, as well as preoperative THI scores, were highly correlated with the degree of decrease in THI scores postoperatively. The auditory performance of patients older than 40 years did not differ from that of younger patients, but their tinnitus was more improved after CI. In conclusion, tinnitus is a common complaint in patients with cochlear implants, and is more prevalent in elderly implantees. In the present study, CI improved tinnitus in all patients, although the most severe cases had the greatest benefit.     

Patient-based outcomes in patients with primary tinnitus undergoing tinnitus retraining therapy

OBJECTIVE: To determine whether the Tinnitus Handicap Inventory (THI), a validated patient-based outcomes measure, may improve our ability to quantify impact and assess therapy for patients with tinnitus. DESIGN: Nonrandomized, prospective analysis of 32 patients undergoing tinnitus retraining therapy (TRT). Assessment tools included comprehensive audiology, a subjective self-assessment survey of tinnitus characteristics, and the THI. Tinnitus Handicap Inventory scores were assessed at baseline and 6 months following TRT. RESULTS: Baseline analysis revealed significant correlation between the subjective presence of hyperacusis and higher total, emotional, and catastrophic THI scores. Tinnitus Handicap Inventory scores correlated with subjective perception of overall tinnitus effect (P<.001). Mean pure-tone threshold average was 17.4 dB, and mean speech discrimination was 97.0%. There were no consistent correlations between baseline audiologic parameters and THI scores. Following 6 months of TRT, the total, emotional, functional, and catastrophic THI scores significantly improved (P<.001). Loudness discomfort levels also significantly improved (P< or =.02). CONCLUSIONS: There is significant improvement in self-perceived disability following TRT as measured by the THI. The results confirm the utility of the THI as a patient-based outcomes measure for quantifying treatment status in patients with primary tinnitus.     

Tinnitus Retraining Therapy (TRT): outcomes after one-year treatment

The aim of the study is to present our results regarding the efficacy of TRT for tinnitus relief in patients with clinically significant tinnitus compared to a group treated with vasoactive agents. In a nonrandomized prospective study, 63 patients with disabling tinnitus were recruited. Greek translation of the Tinnitus Handicap Inventory (THI) and visual analogue scale (VAS) for annoyance caused by tinnitus when conducting four major activities of everyday life (work, sleep, relaxation and concentration) were examined in a 12-month period. The THI score was significantly improved in the TRT group, as well as mean VAS scores, in all measures. Comparison of the mean improvement of THI and VAS scores after treatment showed significant differences between the two groups, favoring TRT treatment. Our data suggest that TRT is an effective treatment. It reduces the level of annoyance induced by tinnitus and improves the ability of patients to work, sleep, relax or be concentrated.     

Clinical trial on tinnitus patients with normal to mild hearing loss: broad band noise and mixed pure tones sound therapy

Background: Tinnitus treatments present a quandary for clinicians, but no thoroughly satisfactory medical treatments are offered to tinnitus patients.

Objective: We compared sound therapy effects of the broad band noise (BBN) and the mixed pure tones on tinnitus patients with normal to mild hearing loss, and the possible mechanisms were discussed.

Material and methods: This study was a double-blinded randomized controlled trial. The patients in two groups were followed up for three months. We used a BBN in group A, and mixed pure tones of nine different frequencies in group B. The Tinnitus Handicap Inventory (THI) and Visual Analog Scale (VAS) measuring were used to evaluate the handicap, loudness and anxiety of tinnitus.

Results: The THI, VAS scores of group B after 3 months were lower than those at baseline. The VAS scores of group B were lower than those of group A at 8 and 12 weeks.

Conclusions: The mixed pure tones were more advantageous than BBN as the sound therapy for tinnitus patients with normal to mild hearing loss.

Significance: This trial provides a special and effective sound therapy method. Tinnitus patients with normal to mild hearing loss will experience more positive effects.

Effect of Melatonin on Tinnitus

Objective: Evaluate melatonin as a treatment for subjective tinnitus. Study Design: Randomized, prospective, double-blind, placebo-controlled crossover trial. Patients were given 3.0 mg melatonin, which was taken nightly for 30 days followed or preceded by a placebo nightly for 30 days, with a 7-day washout period between medications. Setting: Outpatient, private, neurotology practice. Patients: Thirty patients with subjective tinnitus. Main Outcome Measures: Tinnitus matching, Tinnitus Handicap Inventory (THI), patient questionnaire and interview. Results: The average pretreatment THI score was 33.91 as compared with 26.43 after the placebo and 26.09 after melatonin. The difference in the THI scores between melatonin and placebo treatment were not statistically significant. The average pretreatment THI score for patients who reported overall improvement with melatonin was statistically higher (P = 0.02) than the average pretreatment THI score for patients who reported no improvement with melatonin. Among subjects reporting difficulty sleeping attributable to their tinnitus, 46.7% reported an overall improvement after melatonin compared with 20.0% for placebo (P = 0.04). There was also a statistically significant difference in improvement with melatonin for those patients with bilateral tinnitus compared with those with unilateral tinnitus (P = 0.02). Conclusion: Melatonin has been shown to be useful in the treatment of subjective tinnitus. Patients with high THI scores and/or difficulty sleeping are most likely to benefit from treatment with melatonin. In light of its minimal side effects, melatonin should be a part of the physician's armamentarium in the treatment of tinnitus.     

耳鸣严重程度评估方法的研究

目的探讨合理评估耳鸣严重程度的方法。方法对219例初诊耳鸣患者分别应用耳鸣程度评分法及THI（tinnitus handicap inventory,THI）评分法进行严重程度评估,对两种方法评估的总分及其子项目评分进行相关性分析。结果耳鸣程度评分法与THI评分法的相关系数为0.73（P〈0.001）,按耳鸣程度评分法进行的严重程度分级与THI评分呈正相关,耳鸣程度评分法中耳鸣对情绪的影响及耳鸣对工作和生活、睡眠的影响分别与THI评分中的情绪性评分及功能性评分具有较高的相关性（相关系数分别为0.674、0.703）。耳鸣程度评分法中耳鸣对情绪、工作和生活、睡眠的影响及严重性自我评分4个子项目与总分的相关性较大,耳鸣出现的环境及持续时间2个子项目与总分的相关性较小。结论耳鸣程度评分法与THI评分法的评估理念基本一致,结果相似,但前者更为简单实用,今后可进一步改良部分指标的权重。     

Hearing disorder from music; a neglected dysfunction

Conclusion: Music-induced acute acoustic trauma is not inevitably linked to hearing dysfunction as validated by conventional pure tone audiometry. Tinnitus is often in combination with hyperacusis. Our results point at ‘silent hearing loss’ as the underlying pathology, having afferent nerve terminal damage rather than hair cell loss as the structural correlate.

Objectives: Exposure to loud music is one of the most common causes of acute acoustic trauma, which adolescents and teenagers experience by voluntary exposure to loud music of sound levels up to 110?dB(A).

Methods: The clinical and psychophysical data of 104 consecutive patients with music-induced hearing disorder (MIHD) were analyzed to construct individual hearing and tinnitus profiles. In all cases, tinnitus was the presenting symptom.

Results: Hearing abilities were normal in about two-thirds of the tinnitus patients. Tinnitus was experienced most often as a high-frequency tone (83%). The Tinnitus Handicap Inventory (THI) scores ranged from 0 to 94 with an average score of 43.1. Visual analog scales (VAS) were used to assess tinnitus loudness (average 42.4) and annoyance (average 54.2), and tinnitus awareness was estimated (average 60.3). All VAS values correlated strongly with the THI. Hyperacusis was present in 65% and 71% of the patients reported sleeping disorders.     

The low-power laser in the treatment of tinnitus.

The purpose of this study was to evaluate the low-power laser on the treatment of tinnitus. In a randomized, prospective, double-blind, placebo-controlled trial, either active or placebo low-power laser irradiation was given through the external acoustic meatus of the affected ear towards the cochlea. The active laser applied 50 mW (cw, 830 nm) over a period of 10 min per session. Forty-nine patients with severe, chronic uni- or bilateral tinnitus were studied. The main outcome was measured using psychoacoustical match of tinnitus loudness and pitch, Visual Analogue Scale (VAS) ratings of subjective loudness, annoyance and attention involved, scores on the Tinnitus Handicap Inventory (THI), the Tinnitus Coping Style Questionnaire (TCSQ), and a number of psychosocial questionnaires. The results showed only moderate (18%) subjective improvement with no statistically significant differences between the effects of the active laser and placebo treatments. Also, there were no statistically significant differences in prepost measurements of tinnitus loudness, VAS scores, THI scores, or TCSQ scores for patients treated with active laser compared with those treated with placebo. We conclude that low-power laser treatment is not indicated in the treatment of tinnitus. Reports of significant benefits of this treatment in previous, mostly uncontrolled or single-blinded studies may be explained by the placebo effect.

Evaluation of tinnitus retraining therapy for patients with normal audiograms versus patients with hearing loss

Objective

A few chronic tinnitus patients show normal hearing thresholds in the pure tone audiometry from 125 Hz to 8000 Hz (≤20 dB). We report the characteristics of the course of those patients underwent tinnitus retraining therapy (TRT) compared with other patients suffering from chronic and severe tinnitus.

Retrospective evaluation of secondary effects of hearing aids for tinnitus therapy in patients with hearing loss

ObjectiveAcoustic therapies including hearing aids and tinnitus control instruments are widely used in Japan but without high levels of evidence. The outpatient hearing aid clinic at our institution fits patients with hearing aids and instructs patients on how to use them to control tinnitus if present. In this study, we examined the effects of this approach on tinnitus.MethodsOne hundred and eleven of 138 patients who visited our hearing aid clinic from April 2016 to September 2018 purchased hearing aids after fitting. Sixty-six of these patients (31 men, 35 women; mean age 78.0 ± 8.0 years) had both hearing loss and tinnitus and were enrolled. The tinnitus was bilateral in 41 patients and unilateral in 25 (poor hearing ear, n = 16, good hearing ear, n = 9). Hearing aids were worn bilaterally by 23 patients and unilaterally by 43 (89 devices). Seventeen of the 23 patients wearing bilateral hearing aids had bilateral tinnitus and 6 had unilateral tinnitus, i.e., in 40 ears, the tinnitus side matched the hearing aid side (40 devices) and in 6 ears did not (6 devices). Twenty-four of 43 patients wearing unilateral hearing aids had bilateral tinnitus, meaning that in 24 ears the tinnitus side matched the hearing aid side (24 devices). In six of the remaining 19 cases with unilateral tinnitus, the hearing aid and tinnitus were on the same side (6 devices) and in 13 were on opposite sides (13 devices). Changes in the Tinnitus Handicap Inventory (THI), visual analog scale (VAS, for tinnitus discomfort, severity, and persistence), and Hospital Anxiety and Depression Scale scores were measured immediately before using a hearing aid and 12 months later.ResultsSignificant effects of hearing aids on tinnitus were observed in all subjects (THI, p = 0.0000030), VAS (severity, p = 0.000000066; discomfort, p = 0.0000013). Significant effects were observed with bilateral hearing aids (THI, p = 0.0012; VAS for severity, p = 0.00069; VAS for discomfort, p = 0.00052) and with unilateral hearing aids (THI, p = 0.00055; VAS for severity, p = 0.000034; VAS for discomfort, p = 0.00007). Spearman's rank correlation coefficient showed a significant positive correlation between the THI and VAS scores (p = 0.0033). In cases of bilateral tinnitus, significant differences were observed with bilateral hearing aids (THI, p = 0.011; VAS for severity, p = 0.0019; VAS for discomfort; p = 0.020) and with unilateral hearing aids (THI, p = 0.00069; VAS for severity, p = 0.00071; VAS for discomfort, p = 0.000093).ConclusionAcoustic therapy using hearing aids was effective for tinnitus. Even when bilateral, a unilateral hearing aid is able to improve tinnitus. When unilateral, the ipsilateral hearing aid is able to improve tinnitus.     

Factors related to tinnitus and hyperacusis handicap in older people

Objective: The aim was to assess factors related to tinnitus and hyperacusis handicap in older people. Design: Retrospective cross-sectional. Study sample: Data were gathered for 184 patients with an average age of 69 years. Results: Tinnitus handicap as measured via the Tinnitus Handicap Inventory (THI) was significantly predicted by tinnitus annoyance as measured via the visual analogue scale (VAS) (regression coefficient, b?=?2.9, p?b?=?3.9, p?b?=?0.8, p?b?=?0.07, p?=?0.048). Insomnia scores as measured via the Insomnia Severity Index (ISI) were significantly predicted by scores on the depression subscale of the HADS (b?=?0.46, p?=?0.007). Conclusions: Since tinnitus annoyance significantly predicts tinnitus handicap, it is important to explore factors associated with annoyance that may be useful in designing appropriate rehabilitative interventions aimed at reducing tinnitus handicap in older people. Future studies should explore whether hyperacusis and insomnia in older people with tinnitus need to be managed in conjunction with treatment for depression.     

The effectiveness of transmeatal low-power laser stimulation in treating tinnitus

The aim of this study is to examine the effectiveness of transmeatal low-power laser stimulation (TLLS) in treating tinnitus. This is a prospective, double-blinded, randomized, placebo-controlled trial. Patients with persistent subjective tinnitus as their main symptom were recruited into the study from the outpatient clinics. The recruited patients were randomized into the experimental group or TLLS+ group (patients in this group were prescribed to use TLLS at 5 mW at 650 nM wavelength for 20 min daily and oral betahistine 24 mg twice per day for a total of 10 weeks) and the control group or TLLS? group (patients in this group were prescribed with a placebo device to use and oral betahistine 24 mg twice per day for 10 weeks). All patients were required to answer two sets of questionnaires: the Tinnitus handicap inventory (THI) and visual analogue scales (VAS) symptoms rating scales, before starting the treatment and at the end of the 10-week treatment period. The total score of the THI questionnaire was further graded into five grades, grade 1 being mild and grade 5 being catastrophic. Wilcoxon-signed ranks test and Mann–Whitney test were used to compare and analyze the THI and VAS scores before and after treatment for each group. Changes with p value of <0.05 were considered as statistically significant. Chi square test was used to analyze the change of parameters in categorical forms (to compare between TLLS+ and TLLS–). Changes with p value of <0.05 were considered as statistically significant. Forty-three patients successfully and diligently completed their treatment. It was noted that using any condition of the device, TLLS+ or TLLS?, patient’s tinnitus symptoms improved in terms of THI scores (TLLS+, p value = 0.038; TLLS?, p value = 0.001) or VAS scores with a change of at least one grade (TLLS+, p value = 0.007; TLLS?, p value = 0.002) at p value <0.05 significant level. In contrast when TLLS+ group was compared with TLLS? group, no statistically significant result was obtained. In term of VAS scores, there seems to be no statistically significant improvement in patients’ annoyance, sleep disruption, depression, concentration and tinnitus loudness and pitch heard between the two groups. Transmeatal low-power laser stimulation did not demonstrate significant efficacy as a therapeutic measure in treating tinnitus.
