Tinnitus is a common experience which can have a severe impact on ones quality of life. Whilst there have been reports of historical references to tinnitus, there has not been an international cross-sectional analysis of the vocabulary used for tinnitus. In this study, with 227 respondents (of which 53.3% experiencing tinnitus themselves), we report such an analysis of 252 words or phrases, from 42 languages and 48 countries. The results indicate that the majority of vocabulary used has a negative connotation (63%), though a small minority are positive (4%). Many words used for tinnitus in different languages are onomatopoeic-thus mimicking aspects of the percept experienced-or describe the sound (in total 42% of the vocabulary). The involvement of the ear is implied in some terminology, though other vocabulary expresses the impact. Participants experiencing tinnitus significantly differed on the codes for their proposed words or phrases ( p < 0.001), with the code "internal suffering or irritation or intrusion" being more prevalent and the code "relate to ear" and "sound is phantom or not real or imagined" being less prevalent in this group. This research has implications not only for the vocabulary used for tinnitus in Patient Reported Outcome Measures but also, and importantly, for understanding the vocabulary and lived experiences of people with tinnitus by healthcare professionals., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Baguley, Caimino, Gilles and Jacquemin.)

Tinnitus can be a burdensome condition on both individual and societal levels. Many aspects of this condition remain elusive, including its underlying mechanisms, ultimately hindering the development of a cure. Interdisciplinary approaches are required to overcome long-established research challenges. This review summarizes current knowledge in various tinnitus-relevant research fields including tinnitus generating mechanisms, heterogeneity, epidemiology, assessment, and treatment development, in an effort to highlight the main challenges and provide suggestions for future research to overcome them. Four common themes across different areas were identified as future research direction: (1) Further establishment of multicenter and multidisciplinary collaborations; (2) Systematic reviews and syntheses of existing knowledge; (3) Standardization of research methods including tinnitus assessment, data acquisition, and data analysis protocols; (4) The design of studies with large sample sizes and the creation of large tinnitus-specific databases that would allow in-depth exploration of tinnitus heterogeneity., Competing Interests: KA is employed by Cochlear Company. MJ is employed by WS Audiology. CC is employed by Oticon A/S. These relationships have not influenced the work reported in this paper. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Simoes, Daoud, Shabbir, Amanat, Assouly, Biswas, Casolani, Dode, Enzler, Jacquemin, Joergensen, Kok, Liyanage, Lourenco, Makani, Mehdi, Ramadhani, Riha, Santacruz, Schiller, Schoisswohl, Trpchevska and Genitsaridi.)

Introduction: Subjective tinnitus that is influenced by the somatosensory system is called somatosensory tinnitus (ST). When ST is related to the temporomandibular area, multidisciplinary orofacial treatment can reduce tinnitus severity. It is, however, unknown if we can predict this positive outcome. The aim of this study is to look for prognostic indicators that can predict a positive outcome after multidisciplinary orofacial treatment in patients with ST., Methods: Patients were included when they were diagnosed with temporomandibular-related ST and received a maximum of 18 sessions of orofacial treatment during a 9-week program. Predictors for positive treatment outcome were identified using univariate and multiple logistic regression analyses with the Tinnitus Questionnaire (TQ) and the Tinnitus Functional Index (TFI) as dependent variables., Results: The results of 101 patients were included in the analysis. Immediately after multidisciplinary orofacial treatment, a clinically relevant decrease in TQ score was significantly associated with "shorter duration of tinnitus" [odds ratio (OR) 0.99], "higher initial score on the TQ somatic subscale" (OR 1.52), and "painful palpation of the temporomandibular joint (TMJ)" (OR 2.46). After 9 weeks of follow-up, the "higher initial score on the TQ somatic subscale" remained as the sole predictor (OR 1.44). A clinically relevant decrease on TFI after 9 weeks of follow-up was predicted by "female gender" (OR 2.70), "younger age" (OR 0.96), "shorter duration of the tinnitus" (OR 0.99), "lower pressure pain thresholds (PPT) on TMJ" (OR 0.99), "lower PPT on sternocleidomastoid origin" (OR 0.99), and "better speech in noise perception" (OR 0.88). A multivariate model comprising "shorter duration of tinnitus" and "higher initial score on the somatic subscale of the TQ" correctly predicts the clinically relevant decrease in TQ score after treatment in 68.5%. A second multivariate model comprising "female gender," "younger age," and "shorter duration of the tinnitus" correctly predicts a clinically significant decrease on TFI after follow-up in 68.1%., Conclusion: We were able to identify various prognostic indicators. "Younger female patients" with a "shorter duration of tinnitus" and a "higher initial score on the TQ somatic subscale" appear to have the best prognosis after multimodal orofacial therapy., (Copyright © 2020 van der Wal, Van de Heyning, Gilles, Jacquemin, Topsakal, Van Rompaey, Braem, Visscher, Truijen, Michiels and De Hertogh.)

Introduction: To date, guidelines recommend the use of a stepped care approach to treat tinnitus. The current clinical management of tinnitus frequently consists of audiologic interventions and tinnitus retraining therapy (TRT) or cognitive behavioral therapy (CBT). Due to the high heterogeneity of the tinnitus population and comorbidity of tinnitus with insomnia, anxiety, and depression, these interventions may not be sufficient for every patient. The current study aims to determine whether a bimodal therapy for chronic, subjective tinnitus consisting of the combination of TRT and eye movement desensitization reprocessing (EMDR) results in a clinically significant different efficacy in comparison with the prevailing bimodal TRT and CBT therapy., Methods: Patients were randomized in two treatment groups. The experimental group received the bimodal therapy TRT/EMDR and the active control group received the bimodal therapy TRT/CBT. Evaluations took place at baseline (T 0 ), at the end of the treatment (T 1 ), and 3 months after therapy (T 2 ). The tinnitus functional index (TFI) was used as primary outcome measurement. Secondary outcome measurements were the visual analog scale of tinnitus loudness (VAS Loudness ), tinnitus questionnaire (TQ), hospital anxiety and depression scale (HADS), hyperacusis questionnaire (HQ), global perceived effect (GPE), and psychoacoustic measurements., Findings: The TFI showed clinically significant improvement in both bimodal therapies (mean decrease 15.1 in TRT/CBT; p < 0.001 vs. 16.2 in TRT/EMDR; p < 0.001). The total score on the TQ, HADS, HQ, and VAS Loudness all demonstrated significant decrease after treatment and follow-up ( p < 0.001) in the experimental and the active control group. GPE-measurements revealed that more than 80% (i.e., 84% in TRT/CBT vs. 80% in TRT/EMDR) of the patients experienced substantial improvement of tinnitus at follow up. Treatment outcome remained stable after 3 month follow-up and no adverse events were observed., Conclusion: Both psychotherapeutic protocols result in a clinically significant improvement for patients with chronic subjective tinnitus. No significant different efficacy was found for the TRT/EMDR treatment compared to the combination of TRT and CBT., Clinical Trial Registration: ClinicalTrials.gov, ID: NCT03114878.

Introduction: Tinnitus is a complex symptom requiring a thorough multidisciplinary assessment to construct an individual's tinnitus profile. The Antwerp University Hospital hosts a tertiary tinnitus clinic providing intensive, multidisciplinary tinnitus care in the form of combinational psychological treatment with either Tinnitus Retraining Therapy (TRT)/Cognitive Behavioral Therapy (CBT) or TRT/eye movement desensitization and reprocessing therapy (EMDR), high-definition transcranial direct current stimulation (HD-tDCS), and physical therapy treatment (in cases of somatic influence of the neck or the temporomandibular area). Several factors may contribute to therapy effect of which the role of gender has recently gained more interest. As such, the current manuscript explores gender differences in the outcome of different tinnitus treatments., Methods: Data on treatment outcome of four distinct tinnitus treatments (1. HD-tDCS; 2. orofacial physical therapy; 3. combination TRT + CBT; and 4. combination TRT + EMDR) were pooled and compared. Treatment outcome was assessed via the Tinnitus Functional Index (TFI). Participants completed the TFI at baseline, immediately after treatment and after 9 weeks (±3 weeks) follow-up. To explore the effect of gender on different treatment outcomes, a linear mixed model was designed including Time point , Gender , and Therapy Group as fixed factors as well as all interactions between these factors., Results: TFI scores improved significantly over time regardless of therapy group ( p < 0.0001). A mean TFI decrease of at least 13 points was obtained by all participants except by those in the HD-tDCS. Significant interactions between Gender and Time point were identified in all groups except for the TRT +EMDR group. Female subjects improved more extensively than males in the HD-tDCS ( p = 0.0009) and orofacial therapy group ( p = 0.0299). Contrarily, in the TRT +CBT group, male participants showed a significant improvement whereas the mean TFI scores of female subjects remained on baseline levels ( p = 0.0138)., Conclusion: Our data suggest that male and female tinnitus patients seem to react differently to different therapy options. We strongly encourage further prospective studies to discern the relevance of gender in therapy outcome., (Copyright © 2020 Van der Wal, Luyten, Cardon, Jacquemin, Vanderveken, Topsakal, Van de Heyning, De Hertogh, Van Looveren, Van Rompaey, Michiels and Gilles.)
