Ménière’s disease is an inner-ear disorder caused by endolymphatic hydrops, characterised by recurrent episodes of vertigo, fluctuating hearing loss, and tinnitus. Ménière’s disease can be classified as ‘probable’ and ‘definite’ according to the criteria determined by the Bárány Society.
Methods
This analytical cross-sectional retrospective study included 28 Ménière’s disease patients (15 with definite Ménière’s disease and 13 with probable Ménière’s disease). Vestibular function was assessed using ocular-vestibular evoked myogenic potentials, cervical-vestibular evoked myogenic potentials and caloric test.
Results
The results of these tests were evaluated separately for probable Ménière’s disease and definite Ménière’s disease groups and comparisons were made. Significant differences in vestibular evoked myogenic potential asymmetry rates were observed between the probable Ménière’s disease and definite Ménière’s disease groups, with the definite Ménière’s disease group exhibiting a higher rate of abnormal responses.
Conclusion
This suggests that vestibular evoked myogenic potentials testing may be a valuable tool in distinguishing between these two subtypes of Ménière’s disease. Further research is necessary to validate these findings and explore their implications for clinical practice.
Recent developments have indicated a potential association between tinnitus and COVID-19. The study aimed to understand tinnitus following COVID-19 by examining its severity, recovery prospects, and connection to other lasting COVID-19 effects. Involving 1331 former COVID-19 patients, the online survey assessed tinnitus severity, cognitive issues, and medical background. Of the participants, 27.9% reported tinnitus after infection. Findings showed that as tinnitus severity increased, the chances of natural recovery fell, with more individuals experiencing ongoing symptoms (p < 0.001). Those with the Grade II mild tinnitus (OR = 3.68; CI = 1.89–7.32; p = 0.002), Grade III tinnitus (OR = 3.70; CI = 1.94–7.22; p < 0.001), Grade IV (OR = 6.83; CI = 3.73–12.91; p < 0.001), and a history of tinnitus (OR = 1.96; CI = 1.08–3.64; p = 0.03) had poorer recovery outcomes. Grade IV cases were most common (33.2%), and severe tinnitus was strongly associated with the risk of developing long-term hearing loss, anxiety, and emotional disorders (p < 0.001). The study concludes that severe post-COVID tinnitus correlates with a worse prognosis and potential hearing loss, suggesting the need for attentive treatment and management of severe cases.
The father of Czech music, Bedřich Smetana was a brilliant, patriotic Romantic composer who spent his last decade completely deaf. He became progressively ill in his final years and passed away prematurely at 60 years old. Since then, there have been two main propositions for the etiology of his neurological symptoms, in particular his hearing loss: neurosyphilis or osteomyelitis of the temporal bone.
Methods
This article compares the clinical presentation and pathology of neurosyphilis and osteomyelitis.
Results
This article infers which one is arguably the most likely cause based on Smetana’s own medical history, signs and symptoms and autopsy findings.
Conclusion
Smetana’s clinical presentation and pathological results grant us a clearer picture of his neurological condition and allows us to diagnose his final neurological deterioration as complications of neurosyphilis and not osteomyelitis of the temporal bone.
Ménière’s disease is a chronic inner-ear disease attributed to endolymphatic hydrops. Magnetic resonance imaging with gadolinium allows visualisation of endolymphatic hydrops in vivo and may be an adjunct to diagnosis.
Methods
Thirty-eight patients suspected of having Ménière’s disease underwent T2 weighted three-dimensional fluid-attenuated inversion recovery and true inversion recovery sequence magnetic resonance imaging 4 hours post double-dose intra-venous gadolinium. Presence of endolymphatic hydrops was graded by two radiologists at 0 and 4 months. Correlation to clinical diagnosis was assessed using Fisher’s exact test.
Results
Hydrops was identified in 88 per cent, 17 per cent and 27 per cent of patients with Definite Ménière’s, Probable Ménière’s and Undifferentiated disease, respectively. A significant correlation existed between diagnosis and presence of hydrops. Sensitivity and specificity were 88 per cent and 67 per cent, respectively. Intra- and inter-observer agreement for presence and grading of hydrops was near-perfect and substantial to near-perfect, respectively.
Conclusion
Magnetic resonance imaging demonstrates radiographic hydrops with significant correlation to clinical diagnosis and good intra- and inter-observer agreement.
This study aimed to determine if a history of tinnitus is associated with the risk of developing dementia.
Method
A nationwide population-based case–control study including all eligible adults in Taiwan.
Results
A total of 15 686 patients were included in the study, with 7843 individuals making up each of the case and control groups. Patients with a history of tinnitus were associated with a statistically significant higher risk of being diagnosed with dementia before reaching 65 years old (50 years ≤ age <65 years) (adjusted odds ratio 2.68, 95 per cent confidence interval (CI) 1.19–6.05, p = 0.017). No statistical significance was found among those 65 years and older (adjusted odds ratio 1.17, 95 per cent CI 0.90–1.51, p = 0.235).
Conclusion
A history of tinnitus was associated with a 168 per cent increased risk of being diagnosed with dementia in those aged 50–65 years old. This association was not significant in those older than 65 years.
This study evaluates the safety and utility of Eustachian tube balloon dilatation in treating Eustachian tube dysfunction symptoms in adults without middle-ear disease.
Methods
A prospective cohort study was performed. Adults with dilatory Eustachian tube dysfunction symptoms and no middle-ear disease underwent Eustachian tube balloon dilatation. A clinical assessment including tympanometry, pure tone audiometry, otoscopy, ability to Valsalva, and Eustachian Tube Dysfunction Questionnaire-7 was performed pre-operatively and repeated during a 12-month follow-up period.
Results
Fifteen participants were enrolled. The mean pre-operative Eustachian Tube Dysfunction Questionnaire-7 score of 4.6 reduced to 2.5 at six weeks (P < 0.01), 3.0 at six months (P = 0.02) and 2.6 at 12 months (P < 0.01) post-operatively. All patients without evidence of negative middle-ear pressure had Eustachian Tube Dysfunction Questionnaire-7 score improvements. There were no post-operative complications.
Conclusion
Eustachian tube balloon dilatation is safe and effective at treating Eustachian tube dysfunction in patients with no middle-ear disease or evidence of negative middle-ear pressure.
Hearing loss and tinnitus have been proposed as potential indicators of impaired mental health and brain morphological changes.
Aims
To assess the associations of hearing loss and tinnitus with the risk of depression and anxiety and with brain volume.
Method
We conducted a community-based cohort study including 129 610 participants aged 40−69 years at recruitment to the UK Biobank with a follow-up period during 2006–2021 to estimate the risk of depression and anxiety after detection of hearing loss and reported tinnitus. We also assessed the associations of hearing loss and tinnitus with brain volume in a subsample with available brain magnetic resonance imaging data (N = 5222).
Results
We observed an increased risk of depression among individuals with hearing loss (hazard ratio [HR] 1.14, 95% CI 1.03–1.26), tinnitus (HR 1.30, 95% CI 1.21–1.41) or both (HR 1.32, 95% CI 1.15–1.52), compared with individuals with neither hearing loss nor tinnitus. Similar results were noted for anxiety (HR 1.18, 95% CI 1.07–1.30 for hearing loss; HR 1.32, 95% CI 1.22–1.43 for tinnitus; and HR 1.48, 95% CI 1.30–1.68 for both). Hearing loss was associated with decreased overall brain volume as well as decreased volume of different brain regions. The latter associations disappeared after adjustment for whole intracranial volume. Tinnitus was associated with greater left accumbens and right occipital pole volume after adjustment for the whole intracranial volume.
Conclusions
Individuals with tinnitus are at increased risk of depression and anxiety. Hearing loss, on the other hand, is associated with both mood disorders and altered brain morphology.
This study aimed to assess degree of audiovestibular handicap in patients with vestibular schwannoma.
Methods
Audiovestibular handicap was assessed using the Hearing Handicap Inventory, Tinnitus Handicap Inventory and Dizziness Handicap Inventory. Patients completed questionnaires at presentation and at least one year following treatment with microsurgery, stereotactic radiosurgery or observation. Changes in audiovestibular handicap and factors affecting audiovestibular handicap were assessed.
Results
All handicap scores increased at follow up, but not significantly. The Tinnitus Handicap Inventory and Dizziness Handicap Inventory scores predicted tinnitus and dizziness respectively. The Hearing Handicap Inventory was not predictive of hearing loss. Age predicted Tinnitus Handicap Inventory score and microsurgery was associated with a deterioration in Dizziness Handicap Inventory score.
Conclusion
Audiovestibular handicap is common in patients with vestibular schwannoma, with 75 per cent having some degree of handicap in at least one inventory. The overall burden of handicap was, however, low. The increased audiovestibular handicap over time was not statistically significant, irrespective of treatment modality.
To establish outcomes following photobiomodulation therapy for tinnitus in humans and animal studies.
Methods
A systematic review and narrative synthesis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The databases searched were: Medline, Embase, Cochrane Central Register of Controlled Trials (‘Central’), ClinicalTrials.gov and Web of Science including the Web of Science Core collection. There were no limits on language or year of publication.
Results
The searches identified 194 abstracts and 61 full texts. Twenty-eight studies met the inclusion criteria, reporting outcomes in 1483 humans (26 studies) and 34 animals (2 studies). Photobiomodulation therapy parameters included 10 different wavelengths, and duration ranged from 9 seconds to 30 minutes per session. Follow up ranged from 7 days to 6 months.
Conclusion
Tinnitus outcomes following photobiomodulation therapy are generally positive and superior to no photobiomodulation therapy; however, evidence of long-term therapeutic benefit is deficient. Photobiomodulation therapy enables concentrated, focused delivery of light therapy to the inner ear through a non-invasive manner, with minimal side effects.
Tonic tensor tympani syndrome is found in a subset of tinnitus patients who experience intra-aural and peri-aural symptoms, in addition to their tinnitus, in the absence of clinically detectable pathology. As the syndrome has not been widely reported, this study aims to determine its prevalence and evaluate the effectiveness of current management.
Methods
The tinnitus management clinic records of patients over the past six years were assessed to identify tonic tensor tympani syndrome patients and track their progress based on patient-reported Tinnitus Handicap Index scores. Patients with reversible ear pathology and temporomandibular joint disorder were excluded.
Results
It was found that 13 per cent of the tinnitus management patients fulfilled the criteria for tonic tensor tympani syndrome and 94 per cent of those who returned for follow up showed an improvement in their Tinnitus Handicap Index grades.
Conclusion
This study suggests that tonic tensor tympani syndrome is a significant problem among tinnitus patients and current tinnitus management strategies contribute effectively to helping such patients habituate to their symptoms.
This study was designed to determine whether extended high-frequency audiometry was capable of better differentiating between participants with normal hearing who did or did not have subjective tinnitus.
Methods
A total of 96 study participants were enrolled: 36 patients with unilateral tinnitus, 28 patients with bilateral tinnitus and 32 volunteers as controls. All 96 participants exhibited normal audiometry findings and hearing thresholds. Extended high-frequency audiometry was used to evaluate these patients.
Results
There were differences between the extended high-frequency hearing thresholds of affected and unaffected ears in those with unilateral tinnitus, and in the 20–29-year-old bilateral tinnitus group, at 11.2, 12.5 and 14 kHz. Unilateral tinnitus subgroups had higher extended high-frequency hearing thresholds than those in control subjects, at all extended high frequencies.
Conclusion
Extended high-frequency audiometry can offer additional information regarding the hearing status of patients with tinnitus who exhibit normal pure tone thresholds when analysed via conventional hearing thresholds.
This study investigated the frequency of ear canal protection use and looked at its influence on external auditory exostosis severity and knowledge about external auditory exostosis among windsurfers and kitesurfers on the German coast.
Method
This retrospective cross-sectional study interviewed 130 windsurfers and kitesurfers along the German coast on knowledge of external auditory exostosis, exposure time, use of neoprene hoods and earplugs, and otological complaints. Participants underwent bilateral video-otoscopic examination.
Results
Knowledge of external auditory exostosis was ‘good’ or ‘excellent’ in 78 of 130 (60 per cent) individuals and ‘poor’ or non-existent in 52 of 130 (40 per cent) individuals. Knowledge was positively correlated with hours of exposure, otological complaints and frequency of ear canal protection use. A significant negative influence of neoprene hood use on external auditory exostosis severity was shown.
Conclusion
The positive effect of external auditory exostosis knowledge on the frequency of ear canal protection and the reduction of external auditory exostosis risk implies a need for health education on this topic.
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may be among the viral agents that affect the audio-vestibular system. This study aimed to investigate vestibular symptoms and videonystagmographic examinations in recovered coronavirus disease 2019 (Covid-19) patients compared with the control group.
Method
The patients were evaluated with Vertigo Symptom Scale questionnaire and audiometric, tympanometric, stapedial reflex and videonystagmographic examinations.
Results
A total of 92 of the patients in the coronavirus disease 2019 patients group and 25 of the volunteers in the control group were included in the study. The mean Vertigo Symptom Scale score was found to be significantly higher (p < 0.001) in the coronavirus disease 2019 group. Furthermore, one of the hospitalised patients was diagnosed with vestibular neuritis.
Conclusion
The vestibular system may also be affected in some coronavirus disease 2019 patients. Although this may be seen as dizziness in some patients, in rare cases it can cause severe issues, such as vestibular neuritis.
Patients with hearing loss and tinnitus face lengthy waits to be seen in the ENT clinic. SHOEBOX Audiometry is an iPad-based, audiometric screening tool. A virtual hearing loss and non-pulsatile tinnitus clinic involving an ENT specialist virtually assessing cases based on the SHOEBOX audiogram, a patient symptom questionnaire and the primary care referral letter were implemented. This service evaluation explored the outcomes of the virtual clinic in reducing the need for a face-to-face ENT appointment.
Method
This was a retrospective service evaluation of the first six months of the virtual hearing loss and non-pulsatile tinnitus clinic.
Results
A total of 210 patients were included: 34.8 per cent (73) were discharged without requiring audiologist assessment or an ENT appointment, 51.9 per cent (109) required formal audiological assessment, 36.7 per cent (77) required imaging and only 13.8 per cent (29) required a face-to-face ENT appointment.
Conclusion
A virtual hearing loss and non-pulsatile tinnitus clinic minimised the number of patients requiring a traditional face-to-face clinic appointment within ENT.
Treatment for tinnitus focuses on supportive therapies. Long waiting times in the National Health Service encourage telemedicine options as an alternative. This study aimed to review the literature on telemedicine in the management of tinnitus and analyse its impact on the burden of tinnitus, long-term, anxiety, depression, insomnia and quality of life.
Method
PubMed, Embase, Cochrane Library, Google Scholar, Scopus and Web of Science were searched. English randomised, controlled trials with adult participants suffering from tinnitus were included. A random effects model looking at standardised mean differences between intervention and control groups was utilised.
Results
Eleven randomised, controlled trials were included. Nine studies looked at internet-based cognitive behavioural therapy. A z-value of 9.87 (p < 0.00001; I2 = 21 per cent) showed telemedicine approaches may be better at reducing tinnitus burden compared with passive controls.
Conclusion
Telemedicine options have multiple benefits, but more research will be needed to conclusively say they are better than alternatives.
Depressive symptoms are common in individuals with tinnitus, however, the mechanisms of their interaction are not fully understood. There is neurobiological evidence that might help understanding the interplay between tinnitus and depression which, in turn, helps in making the right choice for treating both conditions.
Objectives
This case report describes a 70-year old female patient that presented with tinnitus and depressive symptoms lasting for the past 5 years.
Methods
The patient showed limited treatment results with different antidepressants. The otorhinolaryngologist ruled out any possible somatic causes of her tinnitus. Tinnitus was causing her sleep disturbances, which worsened her everyday functioning that was already quite poor even further.
Results
After being administered with 30 rounds of TMS, her symptoms either completely resolved or at least reached a level that was adequate for her to start functioning normally on a day-to-day basis.
Conclusions
TMS is a technique that provides non-invasive cortical stimulation, more specifically, when used for depression treatment it stimulates the left dorsolateral prefrontal cortex, a brain region synaptically connected to the limbic system involved in mood regulation that is proven to be hypoactive in depression. The limbic system is where tinnitus-related brain networks and regions involved in the pathophysiology of depression overlap. Further research is needed to deepen the understanding of this topic.
Tinnitus is an auditory perception of a “phantom” nature with highly changing features. There is an established correlation between anxiety, depression, sleep disorders and tinnitus.
Objectives
To evaluate the prevalence of sleep disorders and emotional disorders during tinnitus and their correlation to the severity of the symptomatology
Methods
A descriptive cross-sectional study of 60 patients consulting for subjective tinnitus. For each patient we collected epidemiological data and performed an ENT and general examination, an audiometric and psychoacoustic evaluation and a psychometric evaluation. To evaluate the severity of the tinnitus we used the visual analog scale VAS and the subjective tinnitus severity test (STSS). Disability was assessed by the Tinnitus Handicap Inventory (THI). Anxiety and depression were assessed by: the Hamilton anxiety Rating scale and the Beck depression inventory.
Results
The prevalence of emotional disorders was: 21.7% for depression, 48.33% for generalized anxiety disorder, 11.67% for dysthymia, 5% for agoraphobia 16.67% for panic disorder and 1.67% for social phobia. The intensity of tinnitus was correlated with more panic disorder (p=0.008). Subjective severity of tinnitus was correlated with disability (p=0.0001), awareness of tinnitus in relation to sleep duration (p=0.006) and disturbed sleep (p=0.047). Disability was correlated with subjective tinnitus severity (p=0.0001), panic disorder (p=0.0007), generalized anxiety disorder (p=0.033), and poor sleep quality (p=0.005).
Conclusions
Our results emphasize the importance of emotional disorders as well as sleep disorders in chronic “tinnitus”. These disorders should be systematically investigated and eventually treated in order to optimize the management of the patients.
This study aimed to review the incidence and co-morbidity of functional ear symptoms in new referrals to an adult otology clinic and present a clinical model based on neuroscientific concepts.
Method
This was a retrospective review of 1000 consecutive new referrals to an adult otology clinic.
Results
Functional disorder was the primary diagnosis in 346 patients (34.6 per cent). Functional ear symptoms included tinnitus (69.7 per cent), imbalance (23.7 per cent), otalgia (22.8 per cent) and aural fullness (19.1 per cent), with more than one symptom occurring in 25.1 per cent of patients. Co-morbidities included sensorineural hearing loss (39 per cent), emotional stress (30 per cent) and chronic illness (22 per cent).
Conclusion
Functional disorders commonly present to the otology clinic, often in the presence of emotional stress or chronic illness. They occur because of adaptation of brain circuitry to experience, including adverse events, chronic illness and fear learning. This study presented an experience-driven clinical model based on these concepts. An understanding of these principles will significantly aid otolaryngologists who encounter patients with functional ear symptoms.
Tinnitus is a common auditory disorder in which patients experience noise in the absence of an external source. It is a consequence of irreversible cochlear damage. This study examined the distortion product otoacoustic emissions and P300 components of event-related potentials.
Method
This study included a control group of 25 normal-hearing adults not complaining of tinnitus and a study group that consisted of 45 normal-hearing adults complaining of tinnitus. Measures included patient history, basic audiological evaluation, the Arabic version of Tinnitus Handicap Inventory, distortion product otoacoustic emissions testing and P300 recording.
Results
The study group showed significantly higher hearing thresholds at all frequencies as well as delayed latencies and reduced amplitude of P300. The Tinnitus Handicap Inventory showed mean scores of 35.2 ± 16.9, and the distortion product gram showed higher amplitudes in the control group.
Conclusion
Patients with tinnitus might have neural dysfunction at either peripheral or central levels of the auditory pathway.
Pulsatile tinnitus can be a symptom of vascular pathology. However, many of these pathologies present as incidental findings on scanning for unrelated symptoms. This study investigated whether the pathologies attributed to pulsatile tinnitus could instead be considered incidental findings.
Methods
This retrospective study evaluated imaging results of 272 pulsatile tinnitus cases for clinically relevant pathologies, and examined correlations between the site of symptoms and the imaging findings.
Results
Of 272 patients, 238 (88 per cent) had normal scans, 17 (6 per cent) had clinically insignificant incidental findings, and 18 (7 per cent) had findings requiring further investigation or intervention; regarding these latter 18 patients, findings for 8 patients (42 per cent) did not correlate with the symptomatic side. The rates of intracranial aneurysm and arteriovenous malformation in the pulsatile tinnitus group were comparable to those in normal populations.
Conclusion
The comparable rates of vascular abnormalities within the symptomatic pulsatile tinnitus group, plus clinically relevant findings contralateral to symptoms, suggest that vascular pathologies could be incidental findings rather than causes of pulsatile tinnitus. Evaluation is recommended of the effectiveness of the new National Institute for Health and Care Excellence guidelines for pulsatile tinnitus investigation.
