Correlation analysis of hearing thresholds,validated questionnaires and psychoacoustic measurements in tinnitus patients

One of the most criticized points in tinnitus clinical studies arise from the lack of consensus about measurement methods.AimTo evaluate the correlation between audiometric thresholds, pitch matching (PM), minimum masking level (MML), Tinnitus Handicap Inventory (THI) and the Beck Depression Inventory (BDI) in tinnitus patients.Study designProspective, cross-sectional.Materials and methodsSubjects were submitted to tonal audiometry, PM and MML for tinnitus. They also filled out the THI and BDI. Data was statistically compared for correlation purposes between audiometric thresholds, psycho-acoustic measures and questionnaires.ResultsThere was no statistically significant correlation between THI and MML, both in patients with BDI scores under and over 14 points. There was no statistically significant correlation between the worst hearing frequency and PM, as well as between the cut-off frequency and the PM in patients with descending hearing curves in their audiograms.ConclusionsThere is no statistically significant correlation between psycho-acoustic measures (PM and MML), audiometric thresholds, THI and BDI. Tinnitus is a very complex symptom and isolated measures by psycho-acoustic methods; tinnitus and depression questionnaires are not satisfactory.     

Clinical effect of an active transcutaneous bone-conduction implant on tinnitus in patients with ipsilateral sensorineural hearing loss

ObjectivesThis study investigated the effect of an active transcutaneous bone conduction implant (BoneBridge^?) in the management of tinnitus in patients with unilateral sensorineural hearing loss.MethodsFrom October 2016 to July 2018, 15 patients with unilateral tinnitus accompanied by ipsilateral sensorineural hearing loss received BoneBridge^? implants. Pure-tone average, tinnitus handicap inventory (THI), and a visual analogue scale (VAS) for awareness, loudness, and annoyance were measured before and 6 months after surgery. We defined improvement as a reduction of more than 20% between preoperative and postoperative VAS and THI scores, and changes in the THI of over 7 points were also assessed.ResultsMean THI scores before surgery (72.8 ± 16.1) had significantly improved by 6 months postoperatively (50.9 ± 18.9) (p = 0.003). VAS scores for loudness and annoyance also statistically significantly improved (p = 0.011 and 0.002). The amount of functional hearing gain correlated with changes in VAS scores for annoyance. This correlation was stronger with the improvement of high frequency hearing.ConclusionBoneBridge^? is beneficial in patients with tinnitus accompanied by sensorineural hearing loss. This finding can help select patients who will benefit most from bone conduction implants.     

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

ObjectiveThis 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.MethodsWe 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.ResultsAll 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.ConclusionThe results of this study suggest that treatment with sound therapy may ameliorate the symptoms of chronic tinnitus associated with hearing loss.     

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.     

The Tinnitus Handicap Inventory is a better indicator of the overall status of patients with tinnitus than the Numerical Rating Scale

ObjectivesThe Tinnitus Handicap Inventory (THI) and Numerical Rating Scale (NRS) for awareness, annoyance, loudness, and effect on life are two of the most commonly used questionnaires for patients with tinnitus. This study aimed to determine whether these two questionnaires can comprehensively evaluate the patient's condition and which questionnaire is better as a primary endpoint for tinnitus.Materials and methodsData from 90 patients who visited a university hospital with subjective, non-pulsatile tinnitus and without a history of any psychiatric disorders were reviewed between March 2020 and May 2022. The patients' medical histories, audiological profiles, questionnaires including the THI and NRS, Beck Depression Inventory (BDI), Beck Anxiety Depression (BAI), Hospital Anxiety-Depression Scale (HAD), and the Brief Encounter Psychosocial Instrument (BEPSI) were analyzed.ResultsThe THI had a moderately positive correlation with the NRS for effect on life, annoyance, and loudness. It also had a low positive correlation with the BDI, HAD-A, BEPSI, and BAI. Considering annoyance and loudness, the NRS did not correlate with the other questionnaires, except for the THI (p > 0.05). The NRS for tinnitus awareness correlated with most audiological profiles. The ROC curve analysis revealed that the THI significantly predicted depression, anxiety, and stress. Conversely, none of the four NRS items significantly predicted these psychiatric problems (p > 0.05).ConclusionsUsing the THI as a primary endpoint after interventions rather than the NRS is more reasonable because the THI covers the emotional, functional, and catastrophic aspects of tinnitus, although not the audiological status. To compensate for this, the auxiliary use of NRS for awareness should also be considered.     

Validation of a Korean Version of the Tinnitus Handicap Questionnaire

Objectives

The goal of the present study was to evaluate the reliability and validity of the Korean version of the tinnitus handicap questionnaire (THQ-K).

Methods

A total of 60 patients were included in this study. Patients responded to the THQ-K, the tinnitus handicap inventory (THI), Beck''s depression index (BDI), and the visual analogue scale (VAS) for loudness and pitch, loudness match, and minimum masking level (MML) test were performed.

Results

Internal consistency of the THQ-K was examined using Cronbach coefficient alpha. Cronbach alpha was 0.96. The THQ-K showed a significant correlation with THI, BDI, VAS for distress, and VAS for loudness, but no significant correlation with psychoacoustic measurement of tinnitus, such as loudness match, pitch match, and MML.

Conclusion

The THQ-K is a reliable and valid test for evaluating the degree of handicap due to tinnitus for both research and clinical use.     

Transcutaneous Electric Nerve Stimulation in Chronic Subjective Tinnitus

ObjectiveIt is aimed to determine the therapeutic role of transcutaneous electrical nerve stimulation (TENS) on chronic subjective tinnitus with a randomized and comparative analysis.Method46 individuals with normal hearing, chronic subjective tinnitus, aged 20–65; randomly divided into the study (TENS therapy) and tje control groups. The control group (n = 23) was informed only about tinnitus, while the study group (n = 23) received TENS therapy (20 sessions in 4 weeks). Before TENS therapy, tinnitus-related evaluations of all participants [tinnitus frequency, loudness, minimum masking level (MMS), residual inhibition (RI)] were made and Tinnitus Handicap Inventory (THI), Visual Analogue Scale (VAS), Short Form 36 (SF-36), and The Quality of Life Scale were applied to the participants. These evaluations and questionnaires were repeated after 4 weeks of the therapy.ResultsThere was a significant decrease in the tinnitus severity after TENS therapy in the study group (p = 0.003). Moreover, it was found that VAS (loudness and annoyance), THI (functional, emotional and total score), SF-36 (physical function, physical role, pain, general health, vitality, emotional role and social function) values improved compared to before TENS therapy and the difference was significant (p < 0.05). There was no significant difference between the first and last evaluations of the control group (p > 0.05).ConclusionTENS is an effective, practical and reliable therapy method in reducing severity, loudness, and annoyance of tinnitus, and increasing the quality of life in individuals with chronic subjective tinnitus.     

The effects of dietary and physical activity interventions on tinnitus symptoms: An RCT

ObjectiveSubjective tinnitus is defined as the perception of irregular sound at different frequencies. Although the underlying cause of tinnitus is unclear, increased body weight is known to increase tinnitus symptoms. The present study aimed to determine the effects of dietary and physical activity interventions on tinnitus symptoms.MethodsSixty-three obese subjects with tinnitus aged 20 to 65 years were divided into diet + physical activity (P.A.) (n = 15), diet (n = 16), P.A. (n = 15), and control (n = 17) groups. Dietary records, anthropometric measurements, Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI), Short-Form Health Survey (SF-36), and Visual Analogue Scale (VAS) of all individuals were recorded and compared at the baseline and at study completion.ResultsBody weight decreased in the diet + P.A. (-5.9 (3.5) kg), diet (-3.4 (0.9) kg), and P.A. (-2.0 (2.1) kg) groups compared to the baseline (p < 0.05). There was a more significant decrease in tinnitus frequency, tinnitus severity, and VAS scores in individuals with a weight loss of ≥ 5.0% than in those with < 5.0% (p < 0.05). A decrease of 1 kg/m² in BMI decreased the BDI score by 0.485 units and the THI score by 0.523 units. Step counts were increased in the diet + P.A. (3562.3±739.9) and P.A. (3797.1 ± 1801.1) groups compared to baseline (p < 0.01). Each increase of 1000 steps increased the SF-36 score by 1.592 units and decreased the THI score by 0.750 units (p < 0.05).ConclusionDietary and physical activity interventions, alone or in combination, alleviated tinnitus symptoms and increased quality of life in individuals with tinnitus. Due to its contribution to obesity prevention and positive effects on tinnitus, organizing dietary and physical activity programs for obese individuals with tinnitus would improve these individuals’ quality of life.     

Investigating the efficacy of fluoxetine vs. fluoxetine plus alprazolam (single therapy vs. combination therapy) in treatment of chronic tinnitus: A placebo-controlled study

ObjectiveTo investigate the effect of combination therapy (fluoxetine + alprazolam) and fluoxetine alone in treatment of tinnitus.Material and methods147 participants with chronic tinnitus were divided into three groups (fluoxetine, fluoxetine+ alprazolam, and placebo). Tinnitus Handicap Inventory (THI), Visual Analogue Scale (VAS), Tinnitus Severity Index (TSI), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) used to assess tinnitus. Effect size according to partial Eta square calculated and level of significance was considered as P < 0.05.ResultsFluoxetine reduced VAS, THI, BDI, and increased BAI. The combination therapy significantly reduced VAS, THI, BAI, and BDI. None of them reduced the TSI. The effect size for BAI and BDI were 0.135 (medium) and 0.075 (small), respectively. There was no significant difference between combination and single-drug therapy.ConclusionBoth groups improved THI and VAS. Combination therapy was not significantly different from single-drug treatment. Combination therapy can be considered only according to the psychiatric needs of patients.     

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.     

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.     

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 50mW (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.

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.     

Phase-shift treatment for tinnitus of cochlear origin

Phase-shift treatment is a new tinnitus therapy that aims at sound cancelling. This technique is based on a theory advocating that the induction of a sound wave with a 180° phase-shift compared to the sound experienced by the patient could result in sound cancelling, likely by negation of the cortical perception of tinnitus or residual inhibition, which can be partial or complete. The aim of our study is to compare the effect of phase-shifting generated by the tinnitus phase-out™ device between pure tone tinnitus patients (PTP) and narrow band noise tinnitus patients (NBNP). In present comparative study, we explore the effects of phase-shifting during 6 weeks of phase-out™ therapy in PTP and NBNP. Thirty-five tinnitus patients were included in the study. Twenty-one patients had pure tone tinnitus and 14 patients had narrow band noise tinnitus. The effects on tinnitus were assessed using three separate visual analogue scales (VAS), the tinnitus questionnaire, the hyperacusis questionnaire, the Beck depression inventory, a categorical scale and audiometric measurements. While no differences in VAS were seen after therapy in NBNP, tinnitus increase could be demonstrated in PTP. This increase could be demonstrated for tinnitus loudness (p = 0.002) and tinnitus annoyance (p = 0.014). In conclusion, implementation of phase-shifting did not lead to significant sound cancelling. Our results are discussed and compared to previous studies investigating the effects of phase-out™ in tinnitus patients.     

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.

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)     

Evaluation of Eye Movement Desensitization and Reprocessing in the management of tinnitus. An observational study

ObjectivesTinnitus can induce disabling psychological suffering, requiring an integrative multimodal approach, combining neuromodulation and psychotherapeutic methods. We sought to evaluate the therapeutic efficacy and acceptability of Eye Movement Desensitization and Reprocessing (EMDR) in tinnitus.Materials and methodsThis was a single-center prospective non-comparative study. Inclusion criteria comprised: adult patient, with chronic tinnitus, Tinnitus Handicap Inventory (THI) score > 17, causing psychological distress motivating active treatment after ineffective “classic” treatment (combining advice, sound therapy and first-line drug treatment), and agreement to EMDR therapy. Therapeutic efficacy was defined by a decrease in THI or Visual Analog Scale (VAS) scores. Treatment acceptability was defined by the rate of included patients who completed therapy.ResultsThirty-eight patients were included. There was a significant reduction of 53.5% in THI score in 78.9% of patients (P < 0.0001; 64.8 ± 20.8 before versus 31.8 ± 24.7 after treatment), and of 51% in VAS score in 76.3% of patients (P < 0.0001; 7.24 ± 2.12 before versus 3.58 ± 2.03 after treatment). The treatment acceptability was 86.8%.ConclusionEMDR appeared to be an effective alternative that was acceptable to the majority of patients, after failure of “classic” first-line treatment, improving quality of life in tinnitus patients and thus relieving disability.     

Effects of the reduction of caffeine consumption on tinnitus perception

IntroductionFor many years, excessive caffeine consumption has been touted as an aggravating factor for tinnitus. The pathophysiology behind this effect is probably related to the blockage of adenosine receptors by the action of caffeine on the central nervous system.ObjectiveTo evaluate the effects of reduction of coffee consumption on tinnitus sensation and to identify subgroups more prone to benefit from this therapeutic strategy.Study designProspective.MethodsTwenty-six tinnitus patients who consumed at least 150 mL of coffee per day were selected. All were asked to reduce their coffee consumption. The Tinnitus Handicap Inventory (THI) questionnaire was completed by the patients before and after the reduction of coffee consumption, as well as a visual-analog scale (VAS) graduated from 1 to 10.ResultsTHI and VAS scores were significantly reduced (p < 0.05). In the subgroups less than 60 years old, bilateral tinnitus and daily coffee consumption between 150 and 300 mL showed a significantly greater reduction of THI and VAS scores.ConclusionPatients under 60 years of age with bilateral tinnitus and daily coffee consumption between 150 and 300 mL are more prone to benefit from consumption reduction. Thirty-day observation periods may be helpful for a better therapeutical decision.
