Meta-Analysis Review
In this study, we evaluated the clinical diagnostic value of vestibular evoked myogenic potentials (VEMPs) for endolymphatic hydrops (EH) by systematic review and Meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and area under summary receiver operating characteristic curves (AUC) were calculated. Subgroup analysis and publication bias assessment were also conducted. The pooled sensitivity and the specificity were 49% (95% CI: 46% to 51%) and 95% (95% CI: 94% to 96%), respectively. The pooled positive likelihood ratio was 18.01 (95% CI: 9.45 to 34.29) and the pooled negative likelihood ratio was 0.54 (95% CI: 0.47 to 0.61). AUC was 0.78 and the pooled diagnostic odds ratio of VEMPs was 39.89 (95% CI: 20.13 to 79.03). In conclusion, our present meta-analysis has demonstrated that VEMPs test alone is not sufficient for Meniere's disease or delayed endolymphatic hydrops diagnosis, but that it might be an important component of a test battery for diagnosing Meniere's disease or delayed endolymphatic hydrops. Moreover, VEMPs, due to its high specificity and non-invasive nature, might be used as a screening tool for EH.

Meta-Analysis
OBJECTIVES
To investigate the beneficial effects and safety of intratympanic steroid installation compared with placebo in patients with Menière's disease.
METHODS
We performed a systematic literature search in MEDLINE and EMBASE for existing systematic reviews and individual randomized controlled trials (RCTs). Studies were included if they investigated the usage intratympanic steroids in patients aged 18 and above, with definite or probable Menière's disease. The quality of the identified existing reviews was assessed using the AMSTAR tool. The risk of bias in RCTs was assessed using the Cochrane Risk of Bias Tool and overall quality of the individual outcomes was evaluated using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) method.
RESULTS
The literature search provided four systematic reviews, from which one yielded a sufficient AMSTAR evaluation and subsequently provided three RCTs relevant for inclusion. Due to the lack of sufficient reporting of the data, quantitative synthesis was not applicable. In the qualitative synthesis for the primary outcome, the results from the RCTs showed that there was a slight indication of steroid treatment reducing the frequency of vertiginous attacks. No serious adverse events were reported. Based on the GRADE approach the quality for both findings is very low. No studies reported on the secondary outcomes.
CONCLUSION
The effect of intratympanic steroid treatment in Menière's disease is questionable. There is a great need for further research to sufficiently assess whether steroid treatment may be considered as a safe and effective treatment for patients with Menière's disease.

Meta-Analysis
BACKGROUND
Ménière's disease is a debilitating chronic peripheral vestibular disorder associated with psychiatric co-morbidities, notably depression.
METHODS
Database searches were performed to identify studies that assessed depression in Ménière's disease. Metrics used to diagnose depression were extracted, along with the prevalence of depression in each study.
RESULTS
Fifteen studies from 8 different countries reported on 6587 patients. The weighted average age was 55.3 years (range, 21-88 years). Depression was measured by eight different scales, with Zung's Self-Rating Depression Scale used most often. A weighted proportion of 45.9 per cent of patients (confidence interval = 28.9-63.3) were depressed. Weighted averages (± standard deviations) of Beck's Depression Inventory and the Illness Behavior Questionnaire - Dysphoria were 8.5 ± 7.9 and 2.4 ± 1.7, respectively.
CONCLUSION
The prevalence of depression in patients with Ménière's disease is nearly 50 per cent. Treating otolaryngologists should have a low threshold to screen and refer appropriately. Identifying and treating depression should allow for improvement of overall quality of life in patients with Ménière's disease.

Review
INTRODUCTION
Balance disorders presenting with symptoms of dizziness or vertigo may have significant impact on quality of life and are a recognized risk factor for falls.
OBJECTIVE
The objective of this review was to systematically synthesize the published literature on the epidemiology of balance symptoms and disorders in the adult community population.
METHODS
A search was carried out across PubMed, Medline, and Cochrane databases to identify suitable studies. Studies were eligible for inclusion if they contained data on the epidemiology of symptoms of balance disorders (dizziness and vertigo) or balance disorders sampled from community-based adult populations. Data were collected on prevalence and incidence of balance symptoms and on specific balance disorders. A validated risk-of-bias assessment was carried out.
RESULTS
Twenty eligible studies were identified. The lifetime prevalence estimates of significant dizziness ranged between 17 and 30%, and for vertigo between 3 and 10%. Published point prevalence data exist for Ménière's disease (0.12-0.5%) and for vestibular migraine (0.98%). For benign paroxysmal positional vertigo, 1-year incidence estimates range from 0.06 to 0.6%. There are no community-based studies on the prevalence or incidence of chronic uncompensated peripheral vestibular disorders or vestibular neuritis.
CONCLUSION
Symptoms of dizziness and vertigo are common in the adult population, and data give a coherent picture of community epidemiology. These data can inform rational service planning and much-needed clinical trials in this field. There are insufficient data on specific balance disorders, especially peripheral vestibular disorders such as vestibular neuritis and its long-term sequelae.

Review
Context • Oxidative stress and tissue-damaging, oxygen (O2)-related, free-radical formation is inherent in human metabolism, and the tissues of the ear, nose, and throat (ENT) have an increased exposure to injury from those substances. Because glutathione (GSH) is a major component in an antioxidant defense against oxidative damage in ENT tissues, a review of the impact of lowered GSH and oxidative stress in conditions associated with the upper respiratory tract is warranted. Objective • The review intended to summarize the role that oxidative stress and GSH play. Design • The research team performed a literature review from 1980 to the present that was based on the following keywords: oxidative stress, oxidation, antioxidant, and GSH in common ENT conditions. The review found the following conditions: (1) rhinitis, (2) allergic rhinitis, (3) chronic rhinosinusitis (CRS), (4) CRS with polyps, (5) otitis media with effusion, (6) chronic otitis media (COM), (7) COM and cholesteatoma, (8) tympanic membrane sclerosis, (9) tonsillitis, (10) Meniere's disease, (11) laryngeal conditions, and (12) chronic cough. Results • ENT conditions have been found to be associated with oxidative stress and with low GSH. A limited number of the reviewed studies discussed antioxidant use or repletion of GSH. Although only a few reports support the use of GSH or antioxidants as adjuncts in the management of ENT conditions, no reports of side effects were found related to their use. Conclusions • Many ENT conditions are associated with oxidative stress and decreased GSH, both locally in the affected tissues and systemically. The oxidative stress of those conditions may be related to depletion of GSH, which is increased by the higher levels of O2 in the upper respiratory tract. A small number of studies have reported clinical benefits from the use of an antioxidant or GSH support. The findings of benefits and the lack of reports of side effects suggest that the clinical use of antioxidants and support with GSH in ENT conditions may be considered as adjuncts to conventional management and that more research is warranted.

OBJECTIVE
Social determinants of health (SDOHs), including but not limited to sex, race, socioeconomic status, insurance status, and education level, play a significant role in health disparities and affect health outcomes. The purpose of this systematic review is to examine health disparities in otology within the United States and highlight areas warranting further research.
DATA SOURCES
PubMed, Ovid MEDLINE.
REVIEW METHODS
Our search encompassed all years through January 10, 2021. All peer-reviewed primary literature of any design and publication date regarding health disparities and otology outcomes in the United States was eligible for inclusion. Eligibility assessment was performed via 3 independent investigators.
RESULTS
Of the 6326 unique abstracts identified, 188 studies underwent full-text review, and 52 remained in the final review. The most frequently examined otologic condition was hearing loss (36.5%), followed by cochlear implantation (28.8%) and infection/effusion (15.4%). Vertigo/dizziness (1.9%), Ménière's disease (1.9%), and tinnitus (1.9%) were the least represented otologic conditions. Comprehensive articles on multiple disparity topics were the most common (n = 18), followed by articles on race/ethnicity (n = 11) and socioeconomic status (n = 9). Language (n = 2), education (n = 2), and gender (n = 1) were the least discussed. Over 5-fold the number of articles were published between 2011 and 2020 compared to the preceding decade (42 vs 8).
CONCLUSION
This study captures the existing literature regarding health disparities and outcomes in otology. The lack of robust data suggests the need for future quality studies aimed at investigating disparities in otologic care, as well as a broader push for recording and reporting SDOHs.

Meta-Analysis
OBJECTIVES
A recently devised parameter of vestibular-evoked myogenic potential (VEMP) based on the principles of frequency tuning is the inter-frequency amplitude ratio (IFAR). It refers to the ratio of the amplitude of 1000 Hz tone burst evoked VEMP to 500 Hz evoked tone burst. A pathology like Meniere's disease changes the frequency response and alters the frequency tuning of the otolith organs. Because IFAR is based on the principle of frequency tuning of VEMP, it is likely to help identify Meniere's disease. Few studies in the last decade have investigated the utility of IFAR in identifying Meniere's disease. However, a systematic review and a meta-analysis on IFAR in Meniere's disease are lacking. The present study investigates whether the IFAR of VEMP helps identify Meniere's disease and differentiates it from healthy ears and other vestibular pathologies.
DESIGN
The present study is a systematic review and a meta-analysis. The studies investigating the IFAR of cervical and ocular VEMPs in Meniere's disease, healthy controls, and other vestibular pathologies were searched across research databases such as PubMed, Science Direct, and Scopus. The search strategy was developed using the PICO (population, intervention, comparison, and outcomes) format, and Medical Subject Headings (MeSH) terms and Boolean operators were employed. The systematic review was performed using the Rayyan software, whereas the Review Manager software was used to carry out the meta-analysis. A total of 16,605 articles were retrieved from the databases. After the duplicate removal, 2472 articles remained. These were eliminated using title screening, abstract screening, and full-length inspections. A total of nine articles were found eligible for quality assessment and meta-analysis, and the New Castle-Ottawa Scale was used for quality assessment. After the data extraction, 24 six articles were found to have the desired data format for the meta-analysis.
RESULTS
The results showed significantly higher IFAR in the affected ears of individuals in the Meniere's disease group than in the control group's unaffected ears. There was no significant difference between the unaffected ears of individuals in the Meniere's disease group and the ears of the control group. The only study on Meniere's disease and benign paroxysmal positional vertigo found significantly larger ocular VEMP IFAR in ears with Meniere's disease than in benign paroxysmal positional vertigo.
CONCLUSIONS
This systematic review and meta-analysis found IFAR efficient in differentiating Meniere's disease from healthy controls. We also found an enhanced IFAR as a potential marker for Meniere's disease. However, more investigations are needed to confirm the utility of an enhanced IFAR value in the exclusive identification of Meniere's disease.

Meta-Analysis
PURPOSE
The purpose of this work is to assess the treatment efficiency of endolymphatic sac surgery in patients with Menière's disease.
METHODS
This study provides a systematic literature review and meta-analysis based on the guidelines of the Cochrane Collaboration and the Preferred Reporting Items for Systematic reviews and Meta-Analyses protocol. The main inclusion criteria of the literature review were the classification categories according to the American Academy of Otolaryngology-Head and Neck Surgery guidelines of 1985 and 1995.
RESULTS
An effect of 9.25 dB postoperative weighted average hearing loss in surgically treated individuals is classified as "clinically not significant" according to American Academy of Otolaryngology-Head and Neck Surgery 85/95. In contrast, the deterioration by 26.23% in speech comprehension is considered as "clinically significant." An improvement of functional level scale assessment by two categories and vertigo control by assessment in category B can be observed.
CONCLUSION
The findings of this meta-analysis indicate that endolymphatic sac surgery may be beneficial as a treatment for Menière's disease in terms of a positive impact on functional level scale and vertigo control while yielding a negative impact on pure tone average hearing loss and on speech comprehension.

Review
OBJECTIVE
(1) Review evidence for the use of oral diuretic medications in the management of Ménière's disease. (2) Analyze therapy-related hearing and vertigo outcomes.
DATA SOURCES
Literature was obtained through directed searches of MEDLINE, EMBASE, Web of Science, EBSCO Host, Cochrane Reviews, and linked citations through seminal papers. We searched independent electronic databases for articles that reported the use of diuretics in patients with Ménière's disease.
REVIEW METHODS
All articles of level 4 evidence or higher, per the Oxford Centre for Evidence-Based Medicine, were included with no limit for number of patients, duration of therapy, or follow-up period. Two independent investigators reviewed the articles for inclusion eligibility. Outcomes were tabulated, including subjective or quantitative measures of hearing, tinnitus, vertigo episode frequency, and medication adverse effects.
RESULTS
Nineteen articles were included from 1962 to 2012 from 11 countries. Twelve retrospective case series, 4 randomized controlled trials, 2 case-control trials, and 1 prospective case series were identified. Six studies investigated isosorbide; 5, hydrochlorothiazide; 2, acetazolamide; 2, chlorthalidone; and 1 each of betahistine, hydrochlorothiazide, chlorthalidone, acetazolamide, hydrochlorothiazide-triamterene, and nimodipine. Eight (42.1%) studies reported hearing outcomes improvement. Fifteen (79.0%) studies reported vertigo outcomes improvement. Ten (52.6%) studies reported no side effects, and 4 studies (21.1%) reported abdominal discomfort. No significant morbidity or mortality was reported in any study.
CONCLUSION
Multiple low evidence-level studies report that oral diuretic therapy may be beneficial in the medical management of Ménière's disease. Improvement in vertigo episode frequency was consistently reported, with less convincing evidence for improvement in hearing outcomes.

Meta-Analysis
BACKGROUND
Meniere's disease (MD) is a chronic condition of the inner ear consisting of symptoms that include vertigo attacks, fluctuating sensorineural hearing loss, tinnitus and aural fullness. Despite availability of various interventions, there is uncertainty surrounding their relative efficacy, thus making it difficult to select the appropriate treatments for MD. The objective of this systematic review was to assess the relative effects of the available pharmacologic and surgical interventions in patients with MD with regard to vertigo and other key patient outcomes based on data from randomized clinical trials (RCTs).
METHODS
Our published protocol registered with PROSPERO (CRD42019119129) provides details on eligibility criteria and methods. We searched various databases including MEDLINE, Embase and the Cochrane Library from inception to December 10th, 2018. Screening at citation and full-text levels and risk of bias assessment were performed by two independent reviewers in duplicate, with discrepancies resolved by consensus or third-party adjudication. Bayesian network meta-analyses (NMA) were performed for hearing change and vertigo control outcomes, along with pairwise meta-analyses for these and additional outcomes.
RESULTS
We identified 2,889 unique citations, that yielded 23 relevant publications describing 18 unique RCTs (n = 1,231 patients). Overall, risk-of bias appraisal suggested the evidence base to be at unclear or high risk of bias. Amongst pharmacologics, we constructed treatment networks of five intervention groups that included placebo, intratympanic (IT) gentamicin, oral high-dose betahistine, IT steroid and IT steroid plus high-dose betahistine for NMAs of hearing change (improvement or deterioration) and complete vertigo control. IT steroid plus high-dose betahistine was associated with the largest difference in hearing improvement compared to placebo, followed by high-dose betahistine and IT steroid (though 95% credible intervals failed to rule out the possibility of no difference), while IT gentamicin was worse than IT steroid. The NMA of complete vertigo control suggested IT gentamicin was associated with the highest probability of achieving better complete vertigo control compared to placebo, followed by IT steroid plus high-dose betahistine. Only two studies related to surgical interventions were found, and data suggested no statistically significant difference in hearing changes between endolymphatic duct blockage (EDB) versus endolymphatic sac decompression (ESD), and ESD with or without steroid injection. One trial reported that 96.5% of patients in EDB group compared to 37.5% of the patients in ESD group achieved complete vertigo control 24 months after surgery (p = 0.002).
CONCLUSION
To achieve both hearing preservation and vertigo control, the best treatment option among the pharmacologic interventions compared may be IT steroid plus high-dose betahistine, considering that IT gentamicin may have good performance to control vertigo but may be detrimental to hearing preservation with high cumulative dosage and short interval between injections. However, IT steroid plus high-dose betahistine has not been compared in head-to-head trials against other interventions except for IT steroid alone in one trial, thus future trials that compare it with other interventions will help establish comparative effectiveness with direct evidence.
