Background/Objectives: Mobile health (mHealth) tools, such as smartphone apps, support person-centred care for persons with hearing loss engaging in the hearing aid management process. Hearing-aid-connected apps are increasingly common in audiological care, making it important to evaluate their availability and quality for clinicians, developers, and end-users. This scoping review aimed to identify, summarize, and synthesize information on clinically available hearing-aid-connected apps and evaluate their quality. Methods: A search of the Apple App Store (Canada) was conducted in August 2024 to identify current hearing-aid-connected apps that support hearing aid management. Metadata and features were extracted, and app quality was assessed using the Mobile Application Rating Scale (MARS). Quality was assessed across four objective domains (engagement, functionality, aesthetics, and information) and one subjective domain. Results: Apps had varying levels of metadata detail, including updates, compatibility, and target populations. All apps included common hearing aid controls (e.g., volume adjustment, microphone directionality), while more specialized features (tinnitus management, health tracking, remote clinician support) varied. High-performing apps scored significantly higher in engagement, functionality, aesthetics, and subjective quality, and all apps scored low in information quality, particularly for evidence and credibility. Conclusions: Findings highlight the need for transparent and informative metadata reporting and patient-centred design to improve clinical awareness, usability, and uptake of hearing-aid-connected apps.

Objectives: The association between tinnitus and obstructive sleep apnea (OSA) has received attention; however, the mechanisms linking both conditions with diverse outcomes are still unclear. This study aimed to evaluate the association between OSA risk and tinnitus, including the OSA-related characteristics affecting tinnitus. Methods: We included participants aged 40–65 years with auditory examinations and STOP-BANG questionnaire between 2019 and 2021 from the Korean National Health and Nutrition Examination Survey data. Possible causative factors for tinnitus were identified using logistic regression analysis. Participants in the low- and high-risk groups for OSA were 1:1 matched using propensity score matching to compare the possible causative factors. Results: The high-risk group exhibited a higher incidence of tinnitus, persistence, and severity. However, when the causative factors of tinnitus were matched, no significant differences were observed. The most likely contributing factors were high-frequency hearing level in the worse ear for the experience and persistence of tinnitus and smoking for the severity of tinnitus. The high-risk group experienced tinnitus more often than the low-risk group, with no differences between the groups when tinnitus-affective factors were controlled. Conclusions: These findings suggest that tinnitus is unaffected by OSA itself but by the hearing loss that accompanies OSA. Full article

Background and Objective: Rheumatoid arthritis (RA) is a systemic autoimmune disease affecting synovial joints including the temporomandibular joint (TMJ). This study aimed to assess the prevalence and characteristics of temporomandibular disorders (TMDs) in RA patients and correlate these findings with disease activity markers. Materials and Methods: This cross-sectional study included 40 RA patients meeting the 2010 ACR/EULAR criteria and 40 healthy subjects (HSs). Research diagnostic criteria for TMD were used to assess TMD. RA severity was evaluated using ESR, CRP, rheumatoid factor (RF), anti-CCP antibodies, Disease Activity Score (DAS) 28, and disease duration. Results: TMD prevalence was significantly higher in RA patients (75%) than in HS. Orofacial pain was a predominant TMD reported in 82.5% of RA patients. In RA patients there was a difference in myofascial pain, TMJ pain, and TMJ sounds in comparison to HS. All masticatory muscles were painful on palpation in RA patients and the pain intensity was higher in RA than in HS. The most painful muscles were the medial pterygoid muscles, the anterior belly of digastric muscle, and the tendon of the temporal muscle. Slight crepitations were the most frequent. Maximal active mouth opening was reduced and negatively correlated with CRP levels. The most frequent jaw function limitations were chewing and yawning difficulties and tinnitus. There were no correlations between TMD and DAS, RF, and disease duration. Conclusions: Active inflammation in RA is a crucial factor reducing mouth opening. TMD screening independent of disease duration should be integrated into RA management protocols, particularly for patients with elevated inflammatory markers, to eliminate other pathological factors contributing to faster TMJ functional changes, TMJ involvement, and the severity of TMD during RA course.

Objective: We aimed to explore the efficacy of repetitive transcranial magnetic stimulation (rTMS) for idiopathic sudden sensorineural hearing loss (ISSNHL) and evaluate the correlation between treatment courses of rTMS and hearing outcomes. Methods: A prospective observational study was conducted at West China Fourth Hospital, Sichuan University, from January 2018 to January 2025. The study enrolled 339 patients (342 affected ears) diagnosed with ISSNHL. Among them, 67 patients (group A) received standard therapy combined with rTMS, while the control group (group B) received conventional therapy only. To verify the correlation between different treatment courses of rTMS and hearing outcomes, patients in Group A were divided into Group A1 (treatment courses ≤ 10) and Group A2 (treatment courses > 10). Hearing thresholds and clinical characteristics were evaluated at admission, discharge day and 6 months post-treatment. The SDRG’s criteria were used for the grading of hearing recovery. Results: Tinnitus (79.89% vs. 75.32%, p = 0.361) and sleep disorders (33.70% vs. 41.14%, p = 0.178) were highly prevalent among patients in group A and group B. 1 Hz rTMS significantly improved these symptoms (PSQI: 52.32% vs. 44.44%, p = 0.032; THI: 16.67 ± 19.41 vs. 8.22 ± 12.77, p = 0.002). Compared to high-tone hearing loss patients, those with low-tone loss in groupA2 showed a more rapid improvement (250 Hz: 17.66 ± 16.59 vs. 14.09 ± 15.58, p = 0.041; 500 Hz: 21.20 ± 18.03 vs. 17.31 ± 16.24, p = 0.036) than grouA1, with benefits sustained at 6-month follow-up (250 Hz: 27.79 ± 18.74 vs. 22.71 ± 18.31, p = 0.012; 500 Hz: 31.89 ± 19.73 vs. 26.49 ± 20.08, p = 0.013). Conclusions: rTMS at 1 Hz, administered in courses > 10 sessions, demonstrated both short-term and long-term beneficial effects in the ISSNHL. Those with low-tone hearing loss exhibit better recovery but a higher chance of relapse than high-tone loss patients. As a non-invasive approach with minimal side effects, rTMS is suitable for routine ISSNHL treatment. Full article

Purpose: This study aimed to evaluate retrospectively self-reported changes in tinnitus severity and distress associated with the COVID-19 pandemic and vaccination using validated self-report instruments. It further explored patient-reported onset of tinnitus following vaccination, gender differences in symptom severity, and associations with psychological distress. Method: A cross-sectional online survey was completed by 189 adults between December 2023 and April 2024. Participants retrospectively self-reported tinnitus onset and severity before, during, and after the COVID-19 pandemic using the Tinnitus Handicap Inventory (THI) and the Tinnitus Reaction Questionnaire (TRQ). Additional items assessed COVID-19 vaccination history, infection status, and adverse vaccine reactions. Repeated measures ANOVAs and chi-square tests were used to examine retrospectively reported longitudinal changes and group differences. Results: Mean THI scores increased significantly over time—before (M = 9.57, SD = 16.00), during (M = 29.97, SD = 32.30), and currently (M = 36.92, SD = 28.04)—with large effect sizes across functional, emotional, and catastrophic subscales (p < 0.001). TRQ scores also were reported to rise from before (M = 7.86, SD = 15.29) to during (M = 26.38, SD = 29.58) and remained elevated at the current time (M = 29.79, SD = 24.00), p < 0.001. Approximately 25.9% and 27.0% of respondents reported new or worsened tinnitus after the first and second vaccine doses, respectively. No significant gender differences in symptom severity were observed. TRQ severity classification revealed a marked shift, with moderate or greater distress increasing from 5.8% (before) to 35.6% (current). Conclusions: Retrospective self-reports indicated that tinnitus burden significantly increased during the COVID-19 pandemic and remained elevated at the time of survey completion. A notable proportion of individuals reported new-onset tinnitus following vaccination, though causality cannot be inferred. These findings highlight the need for continued monitoring and comprehensive care addressing both audiological and psychological components of tinnitus. Full article

Background/Objectives: This study presents a case of chronic internal carotid artery [ICA] occlusion initially misinterpreted as ICA agenesis on magnetic resonance angiography (MRA). The report underscores the importance of retrospective review of prior imaging, particularly computed tomography angiography [CTA], in establishing the correct diagnosis. Case Report: A 70-year-old man presented with persistent headache, pulsatile tinnitus, and intermittent dizziness. Neurological examination and laboratory results were unremarkable. Initial cranial MRA demonstrated absence of flow in the left ICA, raising suspicion of congenital agenesis. However, retrospective evaluation of a CTA performed nine years earlier revealed a well-formed left carotid canal without ICA opacification, confirming the diagnosis of chronic ICA occlusion. Results: Current imaging again showed lack of enhancement in the left ICA, with adequate cerebral perfusion supplied via the contralateral ICA and vertebrobasilar system. Recognition of the preserved carotid canal on earlier CTA clarified the diagnosis as chronic occlusion rather than agenesis. Although surgical or endovascular revascularization was recommended, the patient opted for conservative management. At three months of follow-up, symptoms had improved and clinical monitoring continues. Conclusions: This case underscores the importance of distinguishing ICA agenesis from chronic occlusion, particularly by evaluating the carotid canal on CT. The presence of a carotid canal strongly indicates prior patency of the ICA and supports a diagnosis of occlusion. Careful differentiation is critical to avoid misinterpretation and to guide appropriate clinical management. In addition, reviewing prior imaging can be valuable when current findings are inconclusive or potentially misleading. Since this is a single case report, these observations should be regarded as hypothesis-generating rather than definitive, and further studies are needed to validate their broader applicability.

Background/Objectives: Hearing loss is a disorder that develops because of being exposed to high noise levels affecting the quality of life among affected individuals. A review of the literature was conducted to explore the prevalence of hearing loss and its associated factors among workers in the metal industry. Methods: The literature search was conducted on ScienceDirect, Google Scholar, Pub Med, ResearchGate and African Journals Online databases to identify articles according to the Preferred Reporting Items for Systematic Reviews and Meta analyses (PRISMA) guidelines. The studies published in scientific journals between January 2014 and December 2024 describing hearing loss and its associated factors among workers in the metal industry were considered for inclusion in the review. The articles were screened by the author. The Critical Appraisal Skills Programme (CASP) quality assessment tool with modified checklist questions was used to evaluate the quality of studies. Results: Following the literature search and using the relevant inclusion criteria, a total of 127 articles were identified, and 8 articles with a total of 2605 participants were included in the review. The sample sizes ranged from 93 to 606. The participants’ age ranged from 19 to 65 years. A review of studies showed varying prevalence of hearing loss ranging from 13.8% to 59%. Furthermore, the studies have found working experience, advanced age, cigarette smoking, tinnitus, working in areas of high noise levels and not using hearing protective devices to be associated with a risk of developing hearing loss. Conclusions: The review found that workers in the metal industry are at risk of developing hearing loss and, therefore, implementation of control measures to prevent the occurrence of hearing loss is necessary.

Background: Despite the widespread use of antibiotics, acute mastoiditis (AM) and related complications resulting from acute purulent otitis media continue to occur, predominantly in children. Although numerous studies have focused on the pathogenesis, aetiological agents, and treatment of AM, comprehensive investigations of the long-term outcomes of AM and the physiological consequences of surgical intervention in the temporal bone are lacking. Methods: Thirty patients who had undergone mastoidectomy for acute mastoiditis at a median age of 2.12 years were invited for evaluation at least five years postoperatively. The assessment included the Chronic Otitis Media Questionnaire 12, clinical examination with otomicroscopy, extended high-frequency pure-tone audiometry, distortion product otoacoustic emissions, middle ear impedance testing, and a newly developed protocol for noninvasive mastoid function measurement. Results were compared with a control group of 30 ears and with a group of 30 ears treated solely with tympanostomy for acute otitis media at risk of mastoiditis. Results: Although mean Chronic Otitis Media Questionnaire 12 scores were below 1 point, patients who had undergone mastoidectomy reported slightly greater difficulties with hearing in both quiet and noisy environments, along with an increased perception of tinnitus and unpleasant sensations around the ear. Otomicroscopy revealed minor structural changes in the test groups, which were absent from the control group. Pure-tone audiometry demonstrated approximately 10 dB higher thresholds at high and extended high frequencies, with similar findings observed in the distortion product otoacoustic emissions. Middle ear impedance testing indicated elevated stapedius reflex thresholds in the mastoidectomy group, while other parameters showed no statistically significant differences. Mastoid function testing demonstrated preserved pressure-buffering capacity but reduced thermal insulation of the vestibular organ under extreme thermal stimulation—an occurrence rarely encountered in daily life. Conclusions: In the long term, most patients recovering from acute mastoiditis exhibit only minor functional and structural sequelae, and the impact of mastoidectomy appears negligible compared with less invasive surgical interventions.

Background/Objectives: Tinnitus often occurs alongside the emotional symptoms of anxiety and depression. The Ginkgo biloba extract EGb 761^® was shown to be effective in reducing neuropsychiatric symptoms in elderly patients with both dementia and tinnitus, exerting direct effects on tinnitus severity and indirect effects mediated by improvement of anxiety, depression, and cognition. Whether the extent of the effects is influenced by the patient’s sex has not yet been investigated. We performed a conditional process analysis to evaluate this question. Methods: We analyzed the moderating role of sex on the direct and indirect effects of EGb 761^® on tinnitus severity using a first- and second-stage conditional process model. Results: Indirect effects of EGb 761^® on tinnitus severity mediated by improved cognition, anxiety, and depression did not differ between women and men (p > 0.05; all 95% bootstrap confidence intervals overlapped with zero). Moreover, direct treatment effects of EGb 761^® on tinnitus severity were statistically significant for both sexes (women, p < 0.0001; men, p = 0.0279). Conclusions: Beneficial effects of Ginkgo biloba extract EGb 761^® in dementia patients with tinnitus are likely to be unaffected by the patient’s sex. Further research into the influence of patient characteristics on the outcome of tinnitus drug treatment is encouraged. Full article

Background and Clinical Significance: Intralabyrinthine schwannoma (ILS) is a rare benign tumor of the inner ear, often presenting with nonspecific symptoms such as hearing loss, tinnitus and vertigo. Vestibular function in ILS patients remains underexplored. This study aims to evaluate vestibulo-ocular reflex (VOR) function and inner ear magnetic resonance imaging (MRI) signal changes in ILS, and to provide insights into potential mechanisms underlying vestibular dysfunction. Case Presentation: We report four cases of MRI confirmed ILS, including two intravestibular and two intravestibulocochlear schwannomas. All patients exhibited unilateral canal paresis on caloric testing, and two of three showed abnormal video head impulse test (vHIT) with decreased VOR gain and corrective saccades. Decreased signal intensity was observed in the semicircular canals in three cases, in the vestibule in one case, and in the cochlea in one case. A systematic literature review including 10 studies (n = 171) showed a 73.3% rate of abnormal caloric responses. Five studies conducted vHIT, reporting reduced mean VOR gain and corrective saccades, though quantitative analysis was limited. Cervical and ocular vestibular evoked myogenic potential abnormalities were found in 68.4% and 65.7% of reported cases, respectively. Conclusions: Impaired VOR function in patients with ILS may result not only from anatomical disruption but also from underlying biochemical or metabolic alterations within the inner ear.

Background/Objectives: Tinnitus has been increasingly recognized not only as an auditory disturbance but also as a condition that is potentially linked to cognitive decline, particularly in older adults. However, the relationship between tinnitus characteristics and cognitive impairment remains underexplored in clinical settings. This study aimed to (1) evaluate the association between chronic tinnitus and cognitive function in adults aged 60 years and above using standardized tools, and (2) determine whether tinnitus severity and duration are associated with increased risk of cognitive impairment. Methods: A cross-sectional study was conducted among 240 older adults, divided into tinnitus (n = 120) and non-tinnitus (n = 120) groups. Cognitive function was assessed using the Mini-Cog (0–5) and SPMSQ (0–10) tools. Tinnitus severity and duration were evaluated using the Tinnitus Handicap Inventory (THI), Visual Analogue Scale (VAS), and duration categories. Results: Participants with tinnitus were significantly older and had higher rates of hearing loss (58.33% vs. 33.33%, p = 0.001), depression (37.50% vs. 18.33%, p = 0.002), and poor sleep quality (51.67% vs. 31.67%, p = 0.003). Mini-Cog and SPMSQ scores were significantly lower in the tinnitus group (2.87 ± 1.14 vs. 3.52 ± 1.06; 6.95 ± 1.42 vs. 8.02 ± 1.18; both p < 0.001). Tinnitus presence, longer duration, and higher severity were independently associated with cognitive impairment. Each 10-point increase in THI score increased the odds of impairment by 45% (OR = 1.45, p < 0.001). Conclusions: Tinnitus burden, particularly when severe and prolonged, is significantly associated with cognitive impairment in older adults. These findings highlight the need for cognitive screening and integrated management in this population. Full article

Background/Objectives: Artificial Intelligence (AI) is increasingly being applied in otolaryngology, including cochlear implants (CIs). This study evaluates the accuracy and completeness of ChatGPT-4 and Microsoft Copilot in determining the appropriate implantation side based on audiological and radiological data, as well as the presence of tinnitus. Methods: Data from 22 CI patients (11 males, 11 females; 12 right-sided, 10 left-sided implants) were used to query both AI models. Each patient’s audiometric thresholds, hearing aid benefit, tinnitus presence, and radiological findings were provided. The AI-generated responses were compared to the clinician-chosen sides. Accuracy and completeness were scored by two independent reviewers. Results: ChatGPT had a 50% concordance rate for right-side implantation and a 70% concordance rate for left-side implantation, while Microsoft Copilot achieved 75% and 90%, respectively. Chi-square tests showed significant associations between AI-suggested and clinician-chosen sides for both AI (p < 0.05). ChatGPT outperformed Microsoft Copilot in identifying radiological alterations (60% vs. 40%) and tinnitus presence (77.8% vs. 66.7%). Cronbach’s alpha was >0.70 only for ChatGPT accuracy, indicating better agreement between reviewers. Conclusions: Both AI models showed significant alignment with clinician decisions. Microsoft Copilot was more accurate in implantation side selection, while ChatGPT better recognized radiological alterations and tinnitus. These results highlight AI’s potential as a clinical decision support tool in CI candidacy, although further research is needed to refine its application in complex cases. Full article

Background: Meniere’s disease is characterized by a triad of vertigo episodes, fluctuating hearing loss, and tinnitus. The disease is followed by a loss of quality of life in patients, with the severity depending on the individual and the stage of the disease. Since there are no quantitatively validated tests that connect all elements of the disease, the only source of subjective data that can be analyzed is the disease diary and questionnaires, among which the MDPOSI (Meniere’s Disease Patient-Oriented Symptom-Severity Index) stands out as a designated quality-of-life assessment tool. This study aims to evaluate the differences in the questionnaire depending on the clinical characteristics of the disease. Methods: The study recruited 60 patients, with clinical variables including age, gender, disease laterality, caloric testing results, and PTA results, the presence of spontaneous nystagmus, pathological values of calorimetric testing, or rotatory chair testing abnormalities. Results: The appearance of spontaneous nystagmus showed a significant association with worse hearing threshold values at 500 Hz (p = 0.036, OR 4.416) and higher. Worse SRT scores correlated with Q1 (p = 0.011), Q2 (p = 0.028), Q4 (p = 0.045), Q5 (p = 0.013), and the total MDPOSI score (p = 0.008, 0.339). Multivariate analysis showed that a higher total value of the MDPOSI questionnaire was statistically significantly associated with older age (p = 0.042) and spontaneous nystagmus (p = 0.037). Conclusions: There is a correlation between the clinical characteristics of Meniere’s disease and the MDPOSI questionnaire, making it useful for assessing quality of life and disease progression.

Objective: Hearing rehabilitation using hearing aids keeps increasing in the general population. Patient-related outcome measures are essential to evaluate benefits. Although the IOI-HA is routinely used in France, its translated version from 2002 has never been validated. This study aimed to assess the psychometric properties of the French version of the IOI-HA questionnaire. Design: Controlled, prospective, monocentric study performed between February 2024 and January 2025. The forward–backward technique was used for translation of the questionnaire. Study Sample: 100 patients fitted with hearing aids completed the questionnaire. Thirty-five patients were retested 15 days after first completion. Results: Internal consistency, assessed by Cronbach’s alpha, was 0.863. Mean IOI-HA item scores ranged from 3.3 to 4.57. All seven items had a high degree of consistency with the total score, except for item Q1 which had a moderate score (0.45). Cronbach’s alpha after item deletion confirmed internal consistency. Intra-class correlation coefficients ranged from 0.622 (Q7) to 0.767 (Q5) and were all statistically significant (p < 0.001), revealing high reliability over time. No significant correlation was found between item scores and age, unilateral or bilateral hearing aid use or accompanying symptoms (tinnitus, dizziness). Conclusions: The French translation of the IOI-HA questionnaire, published in 2002, is a valid and reliable questionnaire evaluating hearing aid satisfaction. This validated questionnaire can now be used in daily clinical practice. Full article

Background/Objectives: Cochlear “injury” is thought to be a significant cause of tinnitus in patients with hearing loss. Interestingly, individuals with normal hearing may also experience tinnitus. This study evaluates otoacoustic distortion product emissions (DPOAEs) in individuals with normal hearing who experience tinnitus perception. Methods: In this prospective study, the tinnitus group (TG) consisted of 34 subjects with tinnitus (four unilaterally) and normal hearing (threshold ≤ 25 dBHL at 0.25–8 kHz). The control group (CG) comprised 10 healthy volunteers (20 ears) without tinnitus and normal hearing. Medical history was recorded, and all participants underwent a complete otolaryngological examination, pure tone audiometry, and DPOAE recording (DP-gram, L1 = 55 dB, L2 = 65 dB, for F2: 619–10,000 Hz). Moreover, participants in the TG completed a detailed tinnitus history (with self-rated loudness scoring) and the Tinnitus Handicap Inventory (Greek-version THI-G) and underwent tinnitus analysis. Results: The recorded mean DPOAE values during the DP-gram of the CG were significantly larger in amplitude at low (t-test, Bonferroni-corrected p < 0.09) and high frequencies (t-test, Bonferroni-corrected p < 0.02) compared with the TG. Tinnitus assessment showed tinnitus pitch matching at the frequency area in the DP-gram, where the acceptance recording criteria were not met. There were no statistically significant differences in tinnitus onset, self-rated loudness scores of >70, and severe disability (THI-G > 58) for TG subjects in whom DPOAEs were not recorded at frequencies of ≤1000 Hz. Participants with abnormal DPOAEs at around 4000 Hz had tinnitus of sudden onset and severe disability (THI-G > 58). Finally, those with pathological recordings of DPOAEs at ≥6000 Hz had gradual onset tinnitus (Pearson Chi-square test, p < 0.05). Conclusions: DPOAEs in normal hearing individuals with tinnitus show lower amplitudes in low and high frequencies compared with normal hearing individuals without tinnitus. The tinnitus matched-frequency coincided with the frequency area where DPOAEs were abnormal. Full article
