Background/Objectives: This study aimed to evaluate the progress in auditory speech perception in a group of children with cochlear implants and additional disabilities, whose implants were implanted at a public hospital in southern Chile between 2013 and 2019. This population has historically been excluded from research due to uncertainties regarding their outcomes. Methods: All pediatric patients who received cochlear implants between 2013 and 2019 were considered for inclusion. After obtaining informed consent, relevant data were collected from their medical records. A total of 18 children met the inclusion criteria. Data analysis was performed using Jamovi software. Results: The minimum age at cochlear implant activation was 2 years, and the maximum was 16.1 years. The median Category of Auditory Performance (CAP) score was 0 pre-implantation and increased to 2 to 12 months post-implantation. Conclusions: Cochlear implantation provides clear benefits for children with additional disabilities. Although gains in auditory perception may be limited in some cases, implantation enables access to the world of sound. Even when oral language development is not fully achieved, parents frequently report positive changes in their children’s interaction with their environment, suggesting an overall improvement in quality of life.

Background/Objectives: Hearing loss (HL) is a prevalent condition that can lead to social exclusion. This review explores the epidemiological, cultural, and social dimensions of HL and examines the barriers to accessibility that individuals with HL encounter. Methods: This research employs a narrative review approach to provide a comprehensive overview of HL, focusing on stigma, gender disparities, cultural and social differences, and accessibility challenges. Results: The review highlights pervasive prejudices surrounding HL and hearing devices. Gender disparities are evident, with Deaf women facing compounded challenges. Cultural perspectives on HL differ widely, ranging from the medical model, which emphasizes treatment using hearing devices, to the Deaf community’s social model, which views deafness as a cultural identity. Socioeconomic disparities further restrict access to modern technologies, particularly in low-income settings, while intersectional discrimination affects marginalized groups within the Deaf community. Public spaces also present significant barriers related to communication, architecture, and technology, which hinder accessibility for individuals with HL. Conclusions: A cultural shift is essential to dismantle societal stereotypes and reduce discrimination associated with HL. Moreover, improving accessibility for individuals with HL necessitates a multifaceted approach, including accessible design, staff training, and the integration of assistive technologies.

Background/Objectives: Hearing loss, particularly in older adults, is associated with reduced physical functioning; increased fall risk; and altered gait patterns, including slower walking speed and shorter step length. While the underlying mechanisms are not fully understood, one possibility is that these gait changes result from an additional cognitive load due to hearing difficulties. Prior research suggests that hearing aids may improve balance; however, their impact on gait remains less well explored. Methods: This study investigated gait parameters in individuals with hearing loss as they walked with and without hearing aid amplification under different dual-task conditions. Additionally, we showed the potential of ear-worn sensors for detecting relevant gait changes. To achieve this, we used a hearing-aid-integrated accelerometer and our open-source EarGait framework comprising gait-related algorithms specifically developed for ear-worn sensors. Results: Our findings revealed no significant differences in gait velocity or step length between the unaided and aided conditions. For stride time, we observed a significant interaction effect; however, the effect size was negligible. The dual-task costs were lower than in previous reports, indicating that the applied dual-task paradigm did not induce the expected cognitive demand. The ear-worn gait analysis system showed strong performance compared to foot-worn sensors. Conclusions: Our findings indicate that in controlled, low-cognitive-demand settings, hearing aid amplification does not affect gait performance and, therefore, neither hinders nor improves walking performance. Additionally, the high accuracy of the ear-worn gait analysis system highlights the strong potential of ear-mounted wearable devices (“earables”) for real-world mobility assessments. Future research should explore more complex real-world conditions to better understand the impact of hearing aids on walking behavior. Our proposed earable-based system offers a promising tool for continuous, unobtrusive gait monitoring in everyday environments. Full article

Background: Cochlear implants (CIs) are the gold standard intervention for severe-to-profound sensorineural hearing loss. Their success depends not only on technological advancements but also on the knowledge, attitudes, and practices (KAP) of otolaryngologists responsible for patient selection, counselling, and postoperative management. Objective: This study aimed to evaluate the KAP of otolaryngologists in the UAE towards CIs, identify gaps in training and decision-making, and assess adherence to global CI protocols. Methods: A cross-sectional study was conducted using a self-administered online questionnaire distributed to otolaryngologists across public and private healthcare institutions in the UAE. The survey assessed demographics, clinical knowledge, attitudes towards CIs, and clinical practices. Descriptive and inferential statistical analyses were performed to assess the relationships among knowledge levels, referral frequency, and institutional factors. Results: A total of 31 otolaryngologists participated. While 74% demonstrated moderate-to-high knowledge of CIs, 39% had low awareness of national guidelines. Most (61%) strongly supported CI integration into treatment protocols, but financial and institutional barriers were frequently cited as challenges. Knowledge levels significantly correlated with referral frequency (p < 0.001), indicating a gap between awareness and practice. Conclusions: This is the first study in the UAE assessing otolaryngologists’ KAP regarding CIs. Despite favourable attitudes, limited guideline awareness, financial barriers, and inconsistent multidisciplinary collaboration remain challenges. Targeted clinician education, standardised CI guidelines aligned with international benchmarks, and improved funding mechanisms are essential to enhance CI accessibility and optimise patient outcomes in the region.

Background/Objectives: In the early stage of presbycusis, patients experience reduced speech perception in noisy environments despite normal audiometry, normally known as hidden hearing loss. Diagnostic indicators like the reduced amplitude of ABR wave I, elevated extended high-frequency threshold (EHT), and decreased middle ear muscle reflex (MEMR) amplitude aim to identify biomarkers of peripheral auditory pathology but remain inconsistent. Mismatch negativity (MMN) is a cortical auditory evoked potential generated when the brain detects sound changes. This study aimed to assess MMN as a diagnostic tool for hidden hearing loss in adults. Methods: Seventy-three subjects with normal hearing underwent an extended pure-tone audiogram examination ranging from 0.125 to 16 kHz and a subsequent MMN assessment with two different paradigms: a speech (ba/da) and a tone (1/2 kHz) paradigm. The MMN’s amplitude and latency were measured and analyzed. Results: The outcome shows a significant age-related effect on MMN amplitude in the speech condition (χ² = 13.0, p = 0.002). Specifically, the MMN amplitude in the 25–30-year-old group was significantly smaller than in the 20–25-year-old group (p = 0.0015, Cohen’s d = 0.63). Additionally, no further effects of age were observed on the cortical potentials examined. Also, neither tone nor speech paradigms showed a significant influence of EHT on the amplitude or latency of either MMN or P300. Conclusions: The application of MMN as an electrophysiological tool to diagnose hidden hearing loss in normal hearing adults has limitations. However, in contrast to MMN responses to tonal stimuli, the present study reveals that MMN amplitude obtained with speech stimuli may indicate early signs of central auditory deficits. Full article

Background: Vestibular function implements head position regulation and body spatial navigation. It matures during childhood and adolescence and integrates with the completion of an individual’s motor development. Nevertheless, vestibular impairment is associated with profound paediatric hearing loss and has a negative impact on the child’s motor proficiency. Cochlear implantation (CI) is the treatment of choice for severe hearing loss, where conservative treatment plans are not appropriate or fail. The Teenager and Young Adults Cochlear Implant (TAYACI) study investigates the long-term outcomes of early implantation with respect to the hearing, speech, psychological, and balance development among CI users. Methods: This study focuses on the vestibular function and the appropriate methods for vestibular assessment. The results of two established vestibular test methods are explored: the video head impulse test (vHIT) and cervical/ocular vestibular-evoked myogenic potentials (cVEMP, oVEMP) with air and bone conduction vibration stimulation. The results of vHIT, cVEMP, and oVEMP, per implanted ear and the relation to the aetiology of hearing loss are reported. An additional dynamic visual acuity (DVA) test was included to assess clinical oscillopsia. Results: Overall abnormal lateral canal testing was detected in 35/76 (46.1%) of the implanted ears. Bone-conducted cVEMP (BC cVEMP) was pathological in 33/76 (43.3%) and BC oVEMP in 42/76 (55.3%). Lateral canal impairment was associated with the background diagnosis of the hearing loss. Oscillopsia was related to bilateral canal impairment (sensitivity 73% specificity 100%). Conclusions: Lateral canal testing together with BC VEMPs were the most reproducible modules for vestibular testing The above tests were related to each other and complemented the overall vestibular assessment. DVA is a helpful tool to screen dynamic oscillopsia in patients with bilateral vestibular impairment. Full article

Background/Objectives: Electrode impedance is crucial for optimizing cochlear implant (CI) stimulation and hearing outcomes. While typically stable, some patients experience unexplained impedance fluctuations. This study used electrode impedance subcomponent analysis to identify the subcomponents contributing to these impedance fluctuations. Methods: This study analyzed clinical electrode impedances and transimpedance matrix (TIM) measurements in 10 CI patients with Nucleus devices (CI422, CI522, or CI622 electrode arrays) who exhibited fluctuating or rising electrode impedances. TIM measurements used a cathodic-leading biphasic pulse (110 CLs, 75 µs/phase, 7 µs interphase interval). Electrode impedances were determined at 6, 12, 18, 24, and 75 µs, and subcomponents (access resistance [near-field/far-field] and polarization impedance [Warburg capacitance/Faraday resistance]) were calculated. Results: Both access resistance and polarization impedance changes contributed to impedance fluctuations. Large changes in near-field resistance compared to far-field resistance were associated with increased resistance to current flow closer to the surface of the electrode. The decreased double-layer capacitance and slightly increased Faraday resistance further suggested increased resistance to charge transfer at the electrode–electrolyte interface. Conclusions: Electrode impedance subcomponent analysis reveals changes in the electrochemical reaction at the electrode surface that cause fluctuating or rising CI electrode impedances. Full article

Background/Objectives: This study investigated whether exposure to various types of information online can influence adults aged 40 and above in their likelihood to purchase hearing aids (HAs). Specifically, it examined the effects of price anchoring, using high or low HA prices in advertisements, and attribute framing, using product descriptions that highlighted lifestyle appeal or technological capabilities. Methods: In a 2 × 2 experimental design, 271 participants browsed a website simulating an online search for hearing health information. Participants then rated their likelihood of purchasing three fictitious HAs as well as their likelihood of not purchasing any device. Results: Two-way ANCOVAs indicated no significant main effects of anchoring or framing on purchase likelihood for the fictitious devices (covariates included self-rated hearing ability, trust in online health information, and HA knowledge and importance). No significant interaction effects emerged. However, exploratory analyses revealed significant anchoring effects for two of the three devices among participants with below-median self-rated hearing. Additionally, self-rated knowledge was a significant covariate in the model for all devices (p < 0.001), positively correlating with purchase likelihood. Participants with above-median self-rated knowledge showed significantly higher purchase likelihood for all devices (p < 0.001, d ≥ 0.572 for all comparisons), while those with below-median knowledge displayed a significant anchoring effect for two outcomes. Conclusions: Enhanced HA knowledge may increase HA purchase likelihood and reduce the potential anchoring effects of online advertising. Further research is needed to determine the impact of exposure to high or low prices on HA purchase decisions, especially among those with poorer hearing. Full article

Background/Objectives: Hearing aid fitting is critical for hearing loss rehabilitation but involves complex, interdependent parameters, while AI-based technologies offer promise, their reliance on large datasets and cloud infrastructure limits their use in low-resource settings. In such cases, expert knowledge, manufacturer guidelines, and research findings become the primary sources of information. This study introduces DHAFES (Dynamic Hearing Aid Fitting Expert System), a personalized, ontology-based system for hearing aid fitting. Methods: A dataset of common patient complaints was analyzed to identify typical auditory issues. A multilingual self-assessment questionnaire was developed to efficiently collect user-reported complaints. With expert input, complaints were categorized and mapped to corresponding hearing aid solutions. An ontology, the Hearing Aid Fitting Ontology (HAFO), was developed using OWL 2. DHAFES, a decision support system, was then implemented to process inputs and generate fitting recommendations. Results: DHAFES supports 33 core complaint classes and ensures transparency and traceability. It operates offline and remotely, improving accessibility in resource-limited environments. Conclusions: DHAFES is a scalable, explainable, and clinically relevant solution for hearing aid fitting. Its ontology-based design enables adaptation to diverse clinical contexts and provides a foundation for future AI integration. Full article

Background: Hearing-related disease is a significant cause of disability worldwide. In resource-limited settings, prevention and early detection are critical for preventing severe disease. Understanding what a population knows and believes with regards to hearing health can be critical in identifying knowledge gaps and developing targeted interventions. Objective: To assess community awareness of hearing health and otitis media (OM) treatment, both modern and traditional, to inform educational programs. Methods: A retrospective review of clinical records from 52 patients (aged 1–79 years) diagnosed with OM during a 3-day hearing health clinic in Kasungu district, Malawi was conducted. Patients diagnosed with OM during the clinic were invited to provide additional details about their hearing health. Surveys contained open-ended questions to assess knowledge and beliefs regarding the cause of their infection and therapies they had previously used for treatment, including home remedies and prescribed medications from allopathic providers or traditional healers. A WHO adapted survey on hearing knowledge was also administered. Results: Hearing loss was identified in 60% of participants. Otoscopy revealed either bilateral or unilateral drainage in 69% of participants and perforation in 73%. Confidence in understanding the causes and treatments of OM was voiced by 60% of participants and 54% had used home remedies as treatment. Of the 11 home remedies used, none aligned with modern medical practice, and only two were recommended by local herbalists. Conclusions: Hearing-related disease contributes significantly to global disability, particularly in resource-limited settings. Educational campaigns to improve hearing health knowledge offer low-cost yet impactful solutions and implementation via partnerships with community leaders and traditional healers can be critical to addressing hearing health challenges. The use of nonantibiotic antimicrobials should be explored further, as these are low-cost and readily available. However, therapeutic alliance between patients and healthcare providers remains crucial. Full article

Background/Objectives: Unilateral hearing loss (UHL) is a relatively common disability condition comprising around 20–50% of all congenital hearing loss (HL). The adverse effects of UHL affect the typical development of auditory function with implications for communication, speech and language acquisition, academic development and quality of life. Current literature suggests an early intervention treatment in order to avoid developmental delays, but there is a lack of evidence about the effectiveness and use of hearing devices. The purpose of the present study was to evaluate the benefits of rehabilitative strategies such as hearing aid (HA) and cochlear implant (CI) in UHL children by exploring audiological and parent-reported outcomes. Methods: A total of 18 UHL children, between the ages of 3 and 17, were enrolled in the study designed as a prospective longitudinal study from July 2023 to July 2024. All children were evaluated for speech perception in quiet and noise and subjective benefits before and after rehabilitative treatment with HA in 15 (83.3%) children and with CI in 3 (16.7%) children. Results: The evaluation of audiological outcomes in children with UHL, based on assessment of aided sound field thresholds and speech perception scores assessment versus unaided, shows improvements in audiometric thresholds and how the hearing devices adequately support listening and spoken language. Scores with hearing devices were significantly higher than baseline-only scores when averaging both SSQ and CHILD questionnaires, pointing to an overall rehabilitative benefit. Conclusions: Rehabilitative interventions, particularly HA and CI, offer notable benefits when introduced early, but achieving optimal outcomes requires a multidisciplinary and individualized approach.

Background/Objectives: A crucial factor for a successful cochlear implant (CI) outcome is an intact auditory nerve (AN). The integrity of the AN can be tested during implantation by measuring electrical auditory brainstem responses (eABR) via the CI. A method that does not require a CI is the use of the auditory nerve test stimulator (ANTS) from MED-EL (Innsbruck, Austria). The aim of the current study was to investigate the cases tested with the ANTS at our clinic and to describe the hearing results following CI for the cases who were implanted with a CI. Methods: All patients underwent preoperative magnetic resonance imaging (MRI) and high-resolution computed tomography (HRCT) to rule out cochlear malformation or retrocochlear pathology. In this study, we described all cases from when we began using the ANTS in 2011. Results: Five patients were tested intraoperatively: three adults with long-term deafness prior to CI and two children with no detectable AN. Three of the five patients were implanted with a CI. All implanted patients in this study could hear with their CIs, even though the speech perception results were limited. Conclusions: The ANTS can be used as a method to assess cochlear nerve function during implantation. The eABR results from the ANTS and the implanted CI were comparable for all cases in our study. Minor changes in waveform latencies were found between ANTS and CI stimulation and may be explained by the insertion depth of the electrode used for stimulation. Full article

Objectives: Evaluating middle ear function is essential for interpreting screening results and prioritizing diagnostic referrals for infants with hearing impairments. Wideband Acoustic Immittance (WAI) technology offers a comprehensive approach by utilizing sound stimuli across various frequencies, providing a deeper understanding of ear physiology. However, current clinical practices often restrict WAI data analysis to peak information at specific frequencies, limiting its comprehensiveness. Design: In this study, we developed five machine learning models—feedforward neural network, convolutional neural network, kernel density estimation, random forest, and support vector machine—to extract features from wideband acoustic immittance data collected from newborns aged 2–6 months. These models were trained to predict and assess the normalcy of middle ear function in the samples. Results: The integrated machine learning models achieved an average accuracy exceeding 90% in the test set, with various classification performance metrics (accuracy, precision, recall, F1 score, MCC) surpassing 0.8. Furthermore, we developed a program based on ML models with an interactive GUI interface. The software is available for free download. Conclusions: This study showcases the capability to automatically diagnose middle ear function in infants based on WAI data. While not intended for diagnosing specific pathologies, the approach provides valuable insights to guide follow-up testing and clinical decision-making, supporting the early identification and management of auditory conditions in newborns.

Background/Objectives: Although newborn hearing screening (NHS) programs have been successfully implemented in many countries worldwide, challenges to these programs have been reported in the literature, such as a lack of awareness among families and healthcare professionals and limited funding. Challenges to the NHS programs in Saudi Arabia have not been systematically reported. This study aimed to assess the level and quality of evidence supporting the existing challenges of the NHS programs in Saudi Arabia. Methods: A systematic review of all peer-reviewed literature on Saudi NHS programs published between 2016 and 2024 was conducted according to the PRISMA guidelines. Search strategies were executed in seven databases. Data were collected from studies that met the inclusion criteria. Results: A total of 37 records were reviewed, and 13 peer-reviewed publications met the inclusion criteria. Characteristics of included studies were classified by study language, study sample, sample size, location of the study sample, study purpose, and study method via evidence tables. Each study was critically appraised according to the quality. Results revealed that cross-sectional prospective description was the main research design with low strength of evidence. Six main challenges were identified and described: lack of awareness and gaps in knowledge, lost to follow-up, inadequate data entry, management, and tracking system, limited or absence of services in some residential areas, insufficient training and frequent changes of NHS personnel, and absence of a standardized NHS protocol. Conclusions: This review may assist in overcoming these challenges and improving the NHS programs in Saudi Arabia. There is a need to establish national education campaigns about the NHS programs, improve documentation by using database management and tracking systems, and expand the early hearing detection and intervention (EHDI) services for children in all Saudi regions.

Background/Objectives: Aural toilet using microsuction is a common procedure in ENT clinics, and vertigo is a frequent complaint during this procedure. This study aimed to investigate the characteristics and incidence of microsuction-induced nystagmus and vertigo based on the appearance of the tympanic membrane (TM). Methods: In 85 patients with various TM appearances, microsuction-induced vertigo and nystagmus were assessed. Results: Microsuction elicited nystagmus in 95% (81 of 85) of patients and vertigo in 36% (31 of 85). The nystagmus direction was towards the ipsilateral ear in a bowing position and towards the contralateral ear in a leaning position. The proportion of patients who complained of rotatory vertigo was significantly higher in those with TM perforation, open cavity mastoidectomy, and adhesive otitis media (74%, 26 of 35) compared to those without TM perforation (10%, 5 of 50) (p < 0.001, X² test). Conclusions: Aural toilet using microsuction commonly induces vertigo due to convection in the lateral semicircular canal endolymph caused by the cooling effect. While microsuction-induced nystagmus was observed in most patients, the incidence of vertigo varied depending on the TM condition. Clinicians should closely monitor patients for vertigo during the procedure, and methods to prevent microsuction-induced vertigo should be explored. Full article

Objectives: This study aimed to translate, cross-culturally adapt, and evaluate the psychometric properties of the Persian version of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (MARS-HA) in elderly Iranian adults. Methods and Materials: This cross-sectional study was conducted in Tehran, 2021. Following translation and cross-cultural adaptation, the face validity, content validity, and reliability of the questionnaire were assessed. The Satisfaction with Amplification in Daily Life (SADL) questionnaire was used to assess concurrent validity. Study participants included 300 hearing-aid users aged 60 years and older who completed the research instruments. Data were analyzed using Confirmatory Factor Analysis (CFA), Cronbach’s alpha coefficient, Pearson correlation coefficient, independent t-tests, and analysis of variance (ANOVA) in SPSS and AMOS version 24. The significance level was set at p ≤ 0.05 for all tests. Results: The mean (SD) age of the participants was 71.38 (8.05) years. The face and content validity of the questionnaire were confirmed by ten experts (CVI > 0.91). The CFA supported the four-factor structure of the questionnaire, and the goodness-of-fit indices indicated that the final model had a good fit. The Cronbach’s alpha for the total questionnaire was 0.93, and for the subscales, it ranged between 0.83 and 0.93. The Pearson’s correlation analysis results showed a positive and significant correlation between MARS-HA and SADL scores (r = 0.61, p < 0.05), supporting criterion validity. Conclusions: The P-MARS-HA questionnaire demonstrates good validity and reliability and can be used as an appropriate tool for assessing self-efficacy in hearing-aid use among elderly Iranian adults.

Family-centred early hearing detection and intervention (FC-EHDI) is an established framework globally recognized for its emphasis on family involvement in supporting children who are deaf and hard of hearing (DHH). In the African context, unique sociocultural and systemic challenges necessitate tailored approaches to ensure effective implementation. This narrative review explores the relevance of FC-EHDI in Africa, highlights barriers to its implementation, and offers recommendations for creating sustainable and culturally aligned interventions. A narrative review methodology synthesizing evidence from African countries to examine the intersection of FC-EHDI with cultural practices, systemic barriers, and opportunities for innovation was adopted. Databases including PubMed, Scopus, Web of Science, and Google Scholar were searched for peer-reviewed journal articles, books, and reports published between 2000 and 2024. Keywords included “family-centred care”, “EHDI”, “Africa”, “cultural responsiveness”, and “early hearing detection and intervention”. Studies were included if they addressed EHDI in African contexts, explored family-centred approaches, or provided barriers and recommendations specific to the region. Thematic analysis was employed to synthesize findings into barriers, evidence, and strategies for FC-EHDI implementation. Data were extracted and analysed thematically to identify patterns and gaps in knowledge. Key challenges identified include resource limitations, economic constraints, linguistic and cultural diversity, and fragmented healthcare systems. Evidence highlights the effectiveness of community-based care, linguistic inclusivity, and culturally tailored interventions in enhancing family engagement and programme outcomes. Recommendations focus on leveraging technology, interdisciplinary collaboration, and policy advocacy. FC-EHDI offers a transformative approach to addressing DHH African children by integrating family involvement, cultural responsiveness, and systemic innovations. Future efforts should emphasize technology, scalable models, and family empowerment to create sustainable and equitable services. Full article

Objectives: This study aimed to analyse the potential influence of abnormalities detected through carotid–vertebral ultrasonography and brain MRI on pure-tone averages (PTAs) and the frequency and intensity of tinnitus. Methods: 423 participants with subjective tinnitus were enrolled in this investigation. All patients underwent carotid– vertebral ultrasonography, brain MRI, and pure-tone audiometry, including tinnitus matching. Results: The median values for tinnitus onset indicated chronic tinnitus in most cases. Regarding tinnitus location, left-sided symptoms (32%) and bilateral symptoms (44%) were the most prevalent. In analysing the effects of abnormalities detected by carotid–vertebral ultrasonography on PTAs, a statistically significant difference was found between the groups (p = 0.0037). Specifically, individuals with intimal hyperplasia had significantly higher PTAs (p = 0.02), as did those with carotid artery plaques (p = 0.005). However, no significant differences in PTAs were noted in relation to carotid artery stenosis (p = 0.07). Similar trends emerged regarding tinnitus intensity (p = 0.013), with significantly higher values observed in the presence of any carotid–vertebral ultrasonography abnormalities. In contrast, tinnitus frequencies were not significantly affected (p = 0.401). Regarding brain MRI findings, Fazekas scores of 2 (p = 0.02) and 3 (p = 0.0052) significantly influenced PTAs. For tinnitus intensity, Fazekas scores of 2 (p = 0.0027) and 3 (p = 0.0005), and the presence of acoustic neuromas (p = 0.019), significantly impacted the intensity values. However, tinnitus frequencies were not significantly (p = 0.36) influenced by brain MRI abnormalities. Conclusions: The findings of this study show that carotid–vertebral ultrasonography and brain MRI abnormalities significantly influence PTAs and tinnitus intensities. Full article

Vestibular paroxysmia (VP) is a disabling medical condition characterized by a high recurrence rate of vertigo. VP is classically associated with the presence of contact between a vascular structure and the cochleovestibular nerve, a neurovascular cross compression (NVCC). Antiepileptic drugs are the first-line treatment for disabling symptoms. We conducted a systematic review to evaluate their efficacy in patients with VP, and whose imaging shows NVCC. All published studies in PubMed databases until October 2024 were included. A total of seven studies were selected. Carbamazepine and oxcarbazepine are by far the most widely used drugs, but there is still a lack of data showing the efficacy of antiepileptic drugs in a large sample of patients. This suggests that a future randomized controlled trial with a satisfactory sample size of VP patients with NVCC and comparing several drugs with neuroprotective properties is needed. Further, as imaging in some of the patients with obvious clinical signs does not always support this diagnosis, we discussed VP physiopathology and the different types of VP published in the literature, including those with no radiological support for NVCC.
