Goal Attainment Scale in tinnitus (GAS-T): treatment goal priorities by chronic tinnitus patients in a real-world setting.

PURPOSE: Standard treatment for tinnitus is cognitive behavioral therapy, although level of evidence of effectiveness is low. There is need for a Goal Attainment Scale to evaluate treatment effects based on patient satisfaction. Preliminary work in a clinical sample has identified six common personal treatment goals. The purpose of this study is to determine whether the preliminary identified goals are confirmed by a heterogeneous sample of people with bothersome tinnitus and to identify any other common personal goals with the intention to construct a closed-end Goal Attainment Scale for tinnitus for use in research of effectiveness of (new) tinnitus treatments. METHODS: Two consecutive polls were plotted in an online peer support group form a heterogeneous sample. First, members were asked to vote for preliminary identified goals and asked to formulate additional personal goals. Corresponding goals were grouped together. Goals that were acknowledged by at least 10% of respondents were used in the second poll in which respondents could vote for statements that they recognized themselves in. RESULTS: The first poll (N = 180) resulted in 15 personal treatment goals. Comparison resulted in five common goals, which were confirmed in the second poll (N = 238): to gain control, to improve well-being and sleep, to reduce effects on hearing and to understand tinnitus. CONCLUSIONS: We expect that if a patient achieves personal goals, he will be likely to reduce healthcare consumption. Based on common personal goals, validity of treatment evaluations is increased. We present a closed-end Goal Attainment Scale in tinnitus.

The effect of anxiety and depression on cognition in older adults with severe-to-profound hearing loss.

PURPOSE: To evaluate the effect of anxiety and/or depression on cognition in older adults with severe-to-profound hearing loss. METHODOLOGY: In total, 83 older subjects (age of 55 years or older) with post-lingual, bilateral, severe-to-profound hearing loss were enrolled in this study between April 2014 and March 2021. The Repeatable Battery for Assessment of Neuropsychological Status for Hearing-impaired individuals (RBANS-H) and the Hospital Anxiety and Depression Scale (HADS) were used to measure cognition and anxiety/depression. RESULTS: A multiple linear regression was used to predict the total RBANS-H score based on the total HADS score, years of education and age of the participants. These variables statistically significantly predicted RBANS-H, F(3, 79) = 12.604, p = 0.010, R2 = 0.324. All three variables added statistically significantly to the prediction, p < 0.05. A higher HADS-score resulted in a significantly lower RBANS-H score with an estimated effect size b1 of - 0.486. In addition, a multiple linear regression was executed for each subdomain of the RBANS-H and its relation to the total HADS-score, age and years of education of the participants. These variables statistically significantly predicted RBANS-H immediate memory F(3, 79) = 16.858, p = 0.003, R2 = 0.390. All three variables added statistically significantly to the prediction, p < 0.05. In the other four subdomains no statistical significance was observed. CONCLUSIONS: Anxiety and/or depression have a significantly negative impact on cognition in individuals with severe-to-profound hearing loss. This negative correlation was mainly attributable to the significantly lower score in the immediate memory subdomain.

Tinnitus suppression by means of cochlear implantation: does it affect cognition?

PURPOSE: Recent literature suggests that tinnitus can impact cognition, but results were varied due to a diversity in investigated aspects of cognition and utilized tests, as well as the possible influence of confounding factors. The purpose of this study was to assess the impact of tinnitus loudness on cognition by use of a within-subjects design in patients with a cochlear implant (CI). In this population, tinnitus loudness can be modulated by switching the CI on or off as CI is known to highly suppress tinnitus. METHODS: A total of 18 CI users completed two versions of the Repeatable Battery for Assessment of Neuropsychological Status for Hearing Impaired individuals (RBANS-H), once in unaided condition and once in best aided condition. Tinnitus suppression was defined as a difference in score on a visual-analogue scale (VAS) of at least one point out of ten between these two conditions. RESULTS: No significant differences in RBANS-H scores were found between the suppression and no suppression group, nor for the suppression group alone. No significant correlations between tinnitus loudness and RBANS-H were found, neither for the suppression group alone, nor for the group as a whole. CONCLUSION: The current study shows no significant effect of tinnitus loudness on cognition, which contradicts previous literature. This discrepancy could be explained by the use of a within-subjects design, which controls for confounding factors. Future research should include a larger and more diverse study sample to draw definitive conclusions on this topic.

Risk Factors for Natural Hearing Evolution in Newborns With Congenital Cytomegalovirus Infection.

Importance: Congenital cytomegalovirus (cCMV) is the major cause of congenital nonhereditary sensorineural hearing loss in children. Currently, criteria to identify infants at increased risk for unfavorable hearing outcome are lacking. Objective: To identify risk factors associated with cCMV-related hearing improvement, hearing deterioration, and late-onset hearing loss. Design, Setting, and Participants: This multicenter cohort study included patients from 6 secondary and tertiary hospitals enrolled in the Flemish CMV registry (Belgium). Newborns with untreated cCMV infection with at least 4-year audiological follow-up were included. Patients who presented with other possible causes of sensorineural hearing loss were excluded. Data were collected for 15 years (January 1, 2007, to February 7, 2022) and analyzed from September 26, 2022, to January 16, 2023. Main Outcomes and Measures: Primary outcome was hearing evolution (per-ear analysis; described as stable hearing, improvement, or deterioration). The association of gestational characteristics, clinical findings, timing of seroconversion, viral load, and hearing status at birth with hearing evolution was investigated using effect sizes (Cramer V, odds ratio [OR], or Hedges g). Results: Of the 387 children, 205 of 385 with nonmissing data were male (53.2%), 113 (29.2%) had a symptomatic infection, and 274 (70.8%) had an asymptomatic infection. Every child was 4 years or older at final hearing evaluation. A total of 701 of 774 ears (90%) showed stable hearing (normal hearing or stable hearing loss since birth) over time. Late-onset hearing loss (normal hearing at birth followed by hearing loss) was present in 43 of 683 ears (6.3%). Among children with hearing loss present at birth, 24 of 34 ears (70.6%) had hearing deterioration, and 6 of 91 ears (6.6%) had hearing improvement. Prematurity was associated with a higher chance of hearing improvement (OR, 12.80; 95% CI, 2.03-80.68). Late-onset hearing loss was more prevalent in a first trimester infection (OR, 10.10; 95% CI, 2.90-34.48). None of the 104 ears of children with a third trimester seroconversion developed late-onset hearing loss. Conclusions and Relevance: Findings of this cohort study support that ongoing audiological follow-up for untreated children with congenital hearing loss is important, as the majority of patients had hearing deterioration. The timing of seroconversion was associated with the risk of developing late-onset hearing loss. These insights can aid in parental counseling, patient stratification, and follow-up. Future research should focus on the effect of treatment, the influence of determined risk factors, and the study of eventual new risk factors in patients at high risk to develop hearing loss.

Prevalence of tinnitus and hyperacusis in 9-12-year-old children.

OBJECTIVES: To estimate the prevalence of tinnitus and hyperacusis in children aged 9-12 years in Flanders, as well as to explore the associations with hearing abilities and listening behaviours. DESIGN: A cross-sectional survey was undertaken in four different Flemish schools. The questionnaire was distributed among 415 children, with a response rate of 97.3%. RESULTS: The prevalence of permanent tinnitus was 10.5% and of hyperacusis was 3.3%. The hyperacusis prevalence was higher in girls (p < .05). Some children reported effects of tinnitus in terms of anxiety (20.1%), sleep (36.5%), and concentration (24.8%). When listening to personal listening devices, 33.5% of the children reported to listen for at least 1 h at 60% or higher of the volume range. Moreover, 54.9% of children stated to never wear hearing protection. CONCLUSIONS: Tinnitus and hyperacusis are prevalent in children aged 9-12 years. Some of these children might be overlooked and, as such, not receiving the required follow-up or counselling. Development of guidelines for the assessment of these auditory symptoms in children would help to determine the prevalence numbers with greater accuracy. Sensibility campaigns for safe listening are warranted, as more than half of the children never use hearing protection.

Risk Factors for Hearing Loss at Birth in Newborns With Congenital Cytomegalovirus Infection.

Importance: With a prevalence between 0.2% and 6.1% of all live births, congenital cytomegalovirus (cCMV) infection is a major cause of congenital nonhereditary sensorineural hearing loss. Despite the large amount of research on cCMV-related hearing loss, it is still unclear which newborns are at risk of hearing loss. Objective: To identify independent risk factors for cCMV-related congenital hearing loss and predictors of hearing loss severity at birth. Design, Setting, and Participants: This cross-sectional study of newborns with cCMV infection used data included in the Flemish CMV registry that was collected from 6 secondary and tertiary hospitals in Flanders, Belgium, over 15 years (January 1, 2007, to February 7, 2022). Data were analyzed March 3 to October 19, 2022. Patients were included in the study after confirmed diagnosis of cCMV infection and known hearing status at birth. Patients who presented with other possible causes of sensorineural hearing loss were excluded. Main Outcomes and Measures: Primary outcome was hearing status at birth. Clinical, neurological, and laboratory findings along with the timing of seroconversion and blood viral load were separately considered as risk factors. Binary logistic regression was performed to identify independent risk factors for congenital hearing loss in newborns with cCMV. Effect sizes were measured using Hedges g, odds ratio, or Cramer V. Results: Of the 1033 newborns included in the study (553 of 1024 [54.0%] boys), 416 (40.3%) were diagnosed with symptomatic cCMV infection and 617 (59.7%) with asymptomatic cCMV infection. A total of 15.4% of the patients (n = 159) presented with congenital hearing loss; half of them (n = 80 [50.3%]) had isolated hearing loss. The regression model revealed 3 independent risk factors for congenital hearing loss: petechiae at birth (adjusted odds ratio [aOR], 6.7; 95% CI, 1.9-23.9), periventricular cysts on magnetic resonance imaging (MRI; aOR, 4.6; 95% CI, 1.5-14.1), and seroconversion in the first trimester (aOR, 3.1; 95% CI, 1.1-9.3). Lower viral loads were seen in patients with normal hearing compared with those with congenital hearing loss (median [IQR] viral load, 447.0 [39.3-2345.8] copies per milliliter of sample [copies/mL] vs 1349.5 [234.3-14 393.0] copies/mL; median difference, -397.0 [95% CI, -5058.0 to 174.0] copies/mL). Conclusions and Relevance: Findings of this cross-sectional study suggest that newborns with cCMV infection and petechiae at birth, periventricular cysts on MRI, or a seroconversion in the first trimester had a higher risk of congenital hearing loss. Clinicians may use these risk factors to counsel parents in the prenatal and postnatal periods about the risk of congenital hearing loss. Moreover, linking clinical features to hearing loss may provide new insights into the pathogenesis of cCMV-related hearing loss. The importance of viral load as a risk factor for congenital hearing loss remains unclear.

Pilot study on the role of somatic modulation in hyperacusis.

BACKGROUND: Hyperacusis is a reduced tolerance to sounds that often co-occurs with tinnitus. Both symptoms have convergent as well as divergent characteristics. Somatic modulation, changes in pitch or loudness during certain movements, is common in patients with a primary complaint of tinnitus. However, thus far, this is not documented in patients with hyperacusis. OBJECTIVES: This study aimed to examine the influence of somatic manoeuvres on the perception of external sounds in patients with a primary complaint of hyperacusis. METHODOLOGY: In this prospective cross-sectional pilot study, 18 patients with a primary complaint of hyperacusis were recruited at the Tinnitus Treatment and Research Center Antwerp (TINTRA). While patients listened to a 1 kHz broadband noise of 30 dB sensation level, six neck manoeuvres (flexion, extension, lateroflexion left/right, traction and compression), three jaw manoeuvres (protrusion, laterotrusion left/right) and one placebo manoeuvre (hand on head) were performed. The primary outcome measure was the change in the perception of the presented sound in terms of loudness and intrusiveness between baseline and each modulation measured by a visual analogue scale (VAS). RESULTS: No overall significant changes were found; however, individual results indicated that five patients presented a clinically relevant change of more than three points out of ten on VAS in terms of hyperacusis after at least one of the executed somatic manoeuvres. CONCLUSIONS: This pilot study did not demonstrate an overall significant change in hyperacusis after somatic manoeuvres but does not rule out the possibility of somatic modulation in some hyperacusis patients. TRIAL REGISTRATION: The protocol of this prospective cross-sectional pilot study was registered on clinicaltrials.gov with registration number NCT04693819.

Associations of Bilateral Vestibulopathy With Cognition in Older Adults Matched With Healthy Controls for Hearing Status.

Importance: Recent literature suggests there may be a significant effect of the vestibular system on cognition and visuospatial processing. Given the increasing prevalence of dementia and individuals at risk for it, exploring possible modifiable risk factors, including vestibular dysfunction, is vital. Objectives: To explore the association of bilateral vestibulopathy (BV) with cognitive function in older adults, taking hearing status into account, and to explore multiple vestibular characteristics and their potential associations with cognition in patients with BV. Design, Setting, and Participants: This cross-sectional study assessed older adults (age 55-84 years) with diagnosed BV from a single center using baseline measurements from the Gehoor, Evenwicht en Cognitie (GECKO) study, an ongoing prospective longitudinal cohort study. Each participant was individually matched with a healthy control based on age, sex, and hearing performance. Data were analyzed in January 2022. Main Outcomes and Measures: The primary outcome measure was cognition, measured by the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing-Impaired Individuals (RBANS-H). Results: A total of 68 patients were assessed, including 34 patients with BV (mean [SD] age, 63.3 [6.0] years; 18 [53%] men) matched with 34 control individuals without BV. Overall, participants with BV had a clinically meaningful lower score on the RBANS-H total scale compared with those without BV (mean [SD] score, 98.62 [12.70] vs 105.91 [11.03]). This decline was most pronounced in the subdomains of immediate memory (mean [SD] score, 107.74 [10.66] vs 112.26 [10.66]), visuospatial cognition (mean [SD] score, 90.06 [13.34] vs 100.47 [13.91]), and attention (mean [SD] score, 94.79 [16.39] vs 102.06 [12.97]). There were no differences in language or delayed memory subdomains. Within the BV population, 1 vestibular parameter (the Performance-Oriented Mobility Assessment, in particular the balance subscale) was associated with lower cognitive scores (r32 = 0.51; 95% CI, 0.20 to 0.72; η2 = 0.26). Other vestibular parameters, including measurements of the peripheral vestibular end organ and questionnaires, showed no association. Conclusions and Relevance: These findings suggest there was an association between vestibular loss and cognitive impairment. Further research on the causal mechanisms underlying this association and the possible impact of vestibular rehabilitation on cognition is needed.

Hyperacusis: demographic, audiological, and clinical characteristics of patients at the ENT department.

PURPOSE: To document whether patients with and without hyperacusis differ from each other on demographic, audiological, and clinical characteristics. METHODS: Based on the Hyperacusis Questionnaire's (HQ) cut-off (HQ > 28), a total of 2301 participants were divided into patients with and without hyperacusis. Demographic data, scores on self-reported questionnaires [Tinnitus Functional Index (TFI), Visual Analogue Scale of tinnitus loudness (VASloudness), Hospital Anxiety Depression Scale (HADS)], and audiological parameters were retrospectively analysed to determine differential factors between the two groups. RESULTS: In total, 10.9% of the patients was classified as hyperacusis patients (n = 251). They reported a significant, higher tinnitus severity (mean difference of 19 points on TFI) and mental distress (mean difference of 4 points on the HADS subscales) (p < 0.001) than patients without hyperacusis. Moreover, this group consisted of more women (45% % in hyperacusis group vs. 35% in non-hyperacusis group) and women scored significantly higher on the HQ (p < 0.001) and TFI (p < 0.01). CONCLUSION: Patients with hyperacusis have distinctive characteristics. The presence of hyperacusis in combination with tinnitus can indicate a higher need for psychoeducation. Patients that present themselves with hyperacusis without tinnitus complaints remain a minority, yet might be underdiagnosed. Hence, future studies should disentangle tinnitus from hyperacusis. In clinical practice, greater efforts are required to increase knowledge about hyperacusis as a primary or secondary complaint and to provide individualized treatment for these patients.

The impact of cochlear implantation on health-related quality of life in older adults, measured with the Health Utilities Index Mark 2 and Mark 3.

PURPOSE: To determine the usefulness of the Health Utilities Index (HUI) in older cochlear implant (CI) recipients, the primary aims were: (1) to assess health-related quality of life (HRQoL), measured with HUI, in older CI candidates while comparing with age- and gender-matched normal-hearing controls; (2) to compare HRQoL after CI with the pre-operative situation, using HUI and the Nijmegen cochlear implant questionnaire (NCIQ). The difference between pre- and postoperative speech intelligibility in noise (SPIN) and in quiet (SPIQ) and the influence of pre-operative vestibular function on HRQoL in CI users were also studied. METHODS: Twenty CI users aged 55 years and older with bilateral severe-to-profound postlingual sensorineural hearing loss and an age- and gender-matched normal-hearing control group were included. HRQoL was assessed with HUI Mark 2 (HUI2), HUI Mark 3 (HUI3) and NCIQ. The CI recipients were evaluated pre-operatively and 12 months postoperatively. RESULTS: HUI3 Hearing (p = 0.02), SPIQ (p < 0.001), SPIN (p < 0.001) and NCIQ (p = 0.001) scores improved significantly comparing pre- and postoperative measurements in the CI group. No significant improvement was found comparing pre- and postoperative HUI3 Multi-Attribute scores (p = 0.07). The HUI3 Multi-Attribute score after CI remained significantly worse (p < 0.001) than those of the control group. Vestibular loss was significantly related to a decrease in HUI3 Multi-Attribute (p = 0.037) and HUI3 Emotion (p = 0.021) scores. CONCLUSION: The HUI is suitable to detect differences between normal-hearing controls and CI users, but might underestimate HRQoL changes after CI in CI users over 55.

Long-term effects of a single psycho-educational session in chronic tinnitus patients.

PURPOSE: To evaluate the effects of a single psycho-educational session on tinnitus burden in chronic tinnitus patients. The session is organized at a tertiary referral center for otologic disorders at the University Hospital Antwerp as a group session (maximum of 10-15 patients a time) lasting for approximately 3-4 h. The session focusses on different aspects of tinnitus. METHODS: The current manuscript reports on 96 patients who completed the Tinnitus Functional Index (TFI), Visual Analogue Scale for mean loudness (VAS), Hyperacusis Questionnaire (HQ), and the Hospital Anxiety and Depression Scale (HADS) prior to treatment and at 6-month follow-up. The TFI was chosen as the primary outcome. Paired-samples T tests were performed to evaluate therapy effect at 6-month follow-up. In addition, a logistic regression model revealed baseline TFI/VAS scores and duration of tinnitus as contributing factors to a significant decrease of the TFI. RESULTS: The TFI total score showed a significant decrease (p < 0.001) at the 6-month follow-up time point. At follow-up, 75% of patients reported their tinnitus to be under control not requiring any additional treatment. The logistic regression model showed that patients with higher baseline TFI scores, lower baseline mean VAS loudness ratings, and shorter tinnitus duration were more likely to show clinically significant improvement on the TFI scale. CONCLUSIONS: Tinnitus Retraining Therapy or Cognitive Behavioural Therapy are effective, though very time-consuming and expensive treatments. A single psycho-educational group session was shown to be highly effective in decreasing the tinnitus burden, which increases feasibility and cost-effectiveness. TRIAL REGISTRATION: Not applicable as this is a retrospective reporting of tinnitus outcome in the daily clinical practice, not a clinical trial.

Prognostic Indicators for Positive Treatment Outcome After Multidisciplinary Orofacial Treatment in Patients With Somatosensory Tinnitus.

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.

Prospective cohort study on the predictors of fall risk in 119 patients with bilateral vestibulopathy.

OBJECTIVES: To identify predictive factors for falls in patients with bilateral vestibulopathy (BV). Specific variables contributing to the general work-up of a vestibular patient were compared between BV patients experiencing falls and those who did not. DESIGN: Prospective multi-centric cohort study. SETTING: Department of Otorhinolaryngology & Head and Neck Surgery at two tertiary referral centers: Antwerp University Hospital and Maastricht University Medical Center. PARTICIPANTS: In total, 119 BV patients were included. BV diagnosis was defined in accordance with the diagnostic BV criteria, established by the Bárány Society in 2017. MAIN OUTCOME MEASURES: Patients were divided into fallers and non-fallers, depending on the experience of one or more falls in the preceding 12 months. Residual vestibular function on caloric testing, rotatory chair testing, video head impulse test (vHIT) and cervical vestibular evoked myogenic potentials (cVEMP) was evaluated as a predictive factor for falls. Furthermore, hearing function (speech perception in noise (SPIN)), sound localization performance, etiology, disease duration, sport practice, scores on the Dizziness Handicap Inventory (DHI) and the Oscillopsia Severity Questionnaire (OSQ) were compared between fallers and non-fallers. RESULTS: Forty-five (39%) patients reported falls. In a sub-analysis in the patients recruited at UZA (n = 69), 20% experienced three or more falls and three patients (4%) suffered from severe fall-related injuries. The DHI score and the OSQ score were significantly higher in fallers. Residual vestibular function, SPIN, sound localization performance, etiology, disease duration, age and sport practice did not differ between fallers and non-fallers. CONCLUSIONS: Falls and (severe) fall-related injuries are frequent among BV patients. A DHI score > 47 and an OSQ score > 27.5 might be indicative for BV patients at risk for falls, with a sensitivity of 70% and specificity of 60%. Residual vestibular function captured by single vestibular tests (vHIT, calorics, rotatory chair, cVEMP) or by overall vestibular function defined as the number of impaired vestibular sensors are not suitable to distinguish fallers and non-fallers in a BV population.

Conservative therapy for the treatment of patients with somatic tinnitus attributed to temporomandibular dysfunction: study protocol of a randomised controlled trial.

BACKGROUND: Tinnitus is a highly prevalent symptom affecting 10-15% of the adult population. It often affects patient quality of life and frequently causes distress. When subjective tinnitus can be elicited by the somatosensory system of the cervical spine or temporomandibular area it is termed somatic tinnitus. The first aim of the current study is to investigate the effect of the best evidence conservative temporomandibular disorder (TMD) treatment on tinnitus in patients with co-existence of tinnitus and TMD or oral parafunctions compared to no treatment. The second aim is to identify a subgroup of patients with tinnitus that benefits from the conservative temporomandibular joint treatment. METHODS AND DESIGN: This study is a randomised controlled trial with a delayed treatment design. Patients with a TMD (TMD pain screener ≥ 3 points) or oral parafunctions (such as clenching and bruxism), who are suffering from moderate to severe subjective tinnitus (Tinnitus Functional Index (TFI) between 25 and 90 points), will be recruited from the tertiary tinnitus clinic of the University Hospital of Antwerp, Edegem, Belgium. Patients will be excluded in case of clear otological or neurological causes of the tinnitus, progressive middle ear pathology, intracranial pathology, traumatic cervical spine or temporomandibular injury in the past 6 months, severe depression as diagnosed by a psychologist, tumours, previous surgery in the orofacial area, substance abuse that may affect the outcome measures, any contra-indication for physical therapy treatment directed to the orofacial area or when they received TMD treatment in the past 2 months. After screening for eligibility, baseline data among which scores on the TFI, tinnitus questionnaire (TQ), mean tinnitus loudness as measured with visual analogue scale (VAS), TMD pain screener, and a set of temporomandibular joint tests will be collected. Patients will be randomised in an early-start group and in a delayed-start group of therapy by 9 weeks. Patients will receive conservative TMD treatment with a maximum of 18 sessions within 9 weeks. At baseline (week 0), at the start of therapy (weeks 0 or 9), 9 weeks after therapy (weeks 9 or 18), and at follow-up (weeks 18 or 27) data from the TFI, TQ, VAS mean tinnitus loudness and the TMD pain screener will be collected. DISCUSSION: Herein, we aim to improve the quality of care for patients with tinnitus attributed to TMD or oral parafunctions. By evaluating the effect of state-of-the-art TMD treatment on tinnitus complaints, we can investigate the usefulness of TMD treatment in patients with somatic tinnitus. TRIAL REGISTRATION: 3 July 2017, version 1 of the protocol, ClinicalTrials.gov NCT03209297 .

A Prospective Randomized Crossover Study in Single Sided Deafness on the New Non-Invasive Adhesive Bone Conduction Hearing System.

BACKGROUND: Recently, an adhesive bone conduction hearing system has been developed for conductive hearing loss or single-sided deafness (SSD). In SSD cases, this device may be a good solution for patients who are unsuitable for, or who do not wish to undergo, bone conduction implant or cochlear implant surgery. The study aimed to investigate the hearing outcomes with the adhesive hearing system in SSD. PURPOSE OF THE STUDY: The study aimed to investigate the hearing outcomes with the adhesive hearing system in SSD. METHODS: A randomized crossover study was conducted in 17 SSD participants, using CROS (contralateral routing of signals) hearing aid as a control. Following outcome measurements were administered after a two-week trial: 1) Speech, Spatial and Qualities scale, Audio Processor Satisfaction Questionnaire, and a custom-made questionnaire about the use of the system, 2) sound localization, 3) speech perception in noise. RESULTS: 70% of the SSD subjects reported that the adhesive hearing system was partially useful or better. Using the APSQ, the adhesive test device was evaluated equally as the control device. Sound localization improved with the adhesive test device and deteriorated with the control device. There was no improvement in speech perception in noise measured with the adhesive test device. Speech perception in noise (SSSDNNH) with the control device improved significantly. CONCLUSION: To the best of our knowledge, this is the first study to report on the outcomes of the new adhesive system. Users' satisfaction of the adhesive hearing system was found to be comparable to the control device. Since the hearing outcomes vary highly between patients, trials with applicable hearing systems are recommended in SSD patients.

Postoperative cognitive dysfunction after cochlear implantation.

PURPOSE: Postoperative cognitive dysfunction (PCD) is a subtle, prolonged deterioration in cognition after surgery. This complication has been frequently investigated, mainly after major (cardiac) surgery. However, the incidence after cochlear implantation is unknown. Therefore, the aim of the study was to investigate the incidence and possible risk factors of PCD in severely hearing-impaired older adults after cochlear implantation. METHODS: In a prospective cohort study, 26 older participants (age: M = 70, SD = 8 years), scheduled for cochlear implantation, were assessed prior to and 1 week after implantation by means of the Montreal Cognitive Assessment (MoCA). The incidence of PCD was calculated. In addition, the following possible risk factors were recorded: age, sex, education, duration of hearing impairment, preoperative signs of depression and anxiety, duration of anesthesia, anesthetic and surgical events and postoperative complications. RESULTS: The incidence of PCD was 11.5%, defined by a Z score of change in MoCA scores ≥ 1.96 (i.e., a decrease of ≥ 4 points). The incidence of PCD was corrected for practice effects by incorporating data from a reference group. Besides an effect of age on the postoperative cognitive performance, no significant risk factors were identified. CONCLUSIONS: The incidence of PCD after cochlear implantation is lower than after major surgeries, but higher than after other minor surgeries. Routine cognitive screening before and after cochlear implantation is recommended to identify patients with PCD and to provide additional care for these patients.

Subjective tinnitus assessment and treatment in clinical practice: the necessity of personalized medicine.

PURPOSE OF REVIEW: Subjective tinnitus can be triggered by a variety of causes, and therefore tinnitus patients constitute a very heterogeneous population difficult to manage. In this article, we reviewed the current literature to present our conceptual model of the conscious auditory percept and tinnitus - based on experimental research - in order to explain the clinical approach to the individual tinnitus patient. RECENT FINDINGS: Fundamental research has provided evidence to support the neurophysiological model of tinnitus developed by Jastreboff. By manipulating the limbic, autonomic and auditory systems, tinnitus retraining therapy (TRT) aims to reduce the response to the abnormal stimulus. Evidence has confirmed the effectiveness of TRT and cognitive behavioral therapy in reducing the negative impact of subjective tinnitus on the patients' quality of life. SUMMARY: Every patient with subjective tinnitus has its unique 'tinnitus profile' which provides a guide to the necessary combination of therapeutic actions. Evidence suggests the multidisciplinary approach combining etiological therapy as well as TRT, and cognitive behavioral therapy in specialized clinics is not only effective in reducing the patient's quality of life but also cost-effective from a healthcare and societal point of view.

Changes over time of psychoacoustic outcome measurements are not a substitute for subjective outcome measurements in acute tinnitus.

The aim of this study was to assess correlations between the changes over time of various tinnitus measurements. A longitudinal prospective study comparing two test moments was performed: before treatment and after 90 days. Tinnitus assessment consisted of psychoacoustic outcome measurements (minimal masking level and loudness matching at 1 kHz) and subjective outcome measurements (Tinnitus Impairment Questionnaire, Tinnitus Questionnaire and Numeric Rating Scale of loudness and annoyance). Additionally, the effect size was measured. 35 subjects were included in this study. The subjects had a permanent, non-pulsatile tinnitus acquired <3 months previously. Weak or no significant correlations were found between ∆psychoacoustic outcome measurements and ∆subjective outcome measurements. The effect size showed that subjective outcome measurements were the most responsive to measure change in tinnitus complaints. We can conclude that psychoacoustic outcome measurements of tinnitus cannot substitute subjective outcome measurements in patients with acute tinnitus. The authors recommend subjective outcome measurements as primary outcome measurements in a clinical setting. In research, however, it is meaningful to quantify tinnitus in both ways.

Using prophylactic antioxidants to prevent noise-induced hearing damage in young adults: a protocol for a double-blind, randomized controlled trial.

BACKGROUND: During leisure activities young people are often exposed to excessive noise levels resulting in an increase of noise-induced symptoms such as hearing loss, tinnitus and hyperacusis. Noise-induced tinnitus is often perceived after loud music exposure and provides an important marker for overexposure as a temporary threshold shift that is often not experienced by the individual itself. As oxidative stress plays an important role in the pathogenesis of noise-induced hearing loss, the use of antioxidants to prevent hearing damage has recently become the subject of research. METHODS: This study proposes a randomized, double-blind, placebo-controlled crossover trial to assess the effects of a prophylactic combination of N-acetylcysteine (600 mg) and magnesium (200 mg) prior to leisure noise exposure in young adults. The primary outcome measure is the tinnitus loudness scored by a visual analogue scale (VAS). Secondary outcome measures are the differences in audiological measurements for the antioxidant treatments compared to placebo intake. Audiological testing comprising of pure tone audiometry including frequencies up to 16 kHz, distortion product otoacoustic emissions, transient-evoked otoacoustic emissions and speech-in-noise testing will be performed prior to and within 7 hours after noise exposure. By use of a mixed effects statistical model, the effects of antioxidants compared to placebo intake will be assessed. DISCUSSION: As adolescents and young adults often do not use hearing protection while being exposed to loud music, the use of preventive antioxidant intake may provide a useful and harmless way to prevent noise-induced hearing damage in this population. Furthermore, when exposed to hazardous noise levels the protection provided by hearing protectors might not be sufficient to prevent hearing damage and antioxidants may provide additive otoprotective effects. Previous research mainly focused on occupational noise exposure. The present study provides a protocol to assess the usefulness of antioxidants during leisure noise activities. TRIAL REGISTRATION: The present protocol is registered at ClinicalTrials.gov: NCT01727492.

Tinnitus: a cross-sectional study on the audiologic characteristics.

BACKGROUND: Patients visiting the department of Otorhinolaryngology-Head and Neck Surgery often recite tinnitus as the primary complaint. Frequently, tinnitus is accompanied by other symptoms such as hyperacusis and hearing loss. The present study is a cross-sectional study analyzing the relationships between tinnitus, hearing loss, and hyperacusis by the use of the audiologic measurements performed in a clinical practice. METHODS: All patients visiting the Otorhinolaryngology-Head and Neck Surgery department of the University Hospital Antwerp with complaints of tinnitus (sometimes accompanied by hyperacusis) during the year of 2012, were looked up (n = 588). All patients underwent audiometry and filled out the Tinnitus Questionnaire (TQ) and Hyperacusis Questionnaire (HQ), and tinnitus analysis was performed. The relationships between all measurements were examined by use of correlations, multinomial logistic regression analyses, and descriptive statistics. RESULTS: Scores on the TQ and HQ were significantly positively correlated (r = 0.5, p < 0.001). In general, patients with a combination of tinnitus and hyperacusis showed significantly higher TQ scores (p < 0.001) and higher ratings on the VAS for loudness and distress (p < 0.001) compared with tinnitus patients without hyperacusis. Furthermore, an age-dependent influence on the audiometric configuration and tinnitus type was found. DISCUSSION: Tinnitus and hyperacusis are two frequent symptoms recited at a consultation. The present study found that patients with a high TQ grade more often also perceive hyperacusis compared with patients with a low TQ grade. CONCLUSIONS: Tinnitus and hyperacusis are two frequent symptoms recited at a consultation. We have to point out that also other issues, such as additional health problems and stress, may influence tinnitus severity. In addition, tinnitus type seems to be age dependent as younger patients more often experience a pure tone tinnitus and older patients more often experience a noise-like tinnitus.
