Review
: Ménière's disease (MD) is a disease of the inner ear, presenting with episodes of vertigo, hearing loss, and tinnitus.The aim of this study is to examine the role of multifrequency tympanometry (MFT) in the diagnosis of MD. A systematic review of MEDLINE (via PubMed), Scopus, Google Scholar, and the Cochrane Library was performed, aligned with the PRISMA guidelines. Only studies that directly compare ears affected by Ménière's disease with unaffected or control ears were included. Random-effects model meta-analyses were performed. Seven prospective case-control studies reported a total of 899 ears, 282 of which were affected by Ménière's disease (affected ears-AE), 197 unaffected ears in patients with MD (UE), and 420 control ears (CE) in healthy controls. No statistically significant differences between the groups were observed regarding resonant frequency (RF). The pure tone audiometry average of the lower frequencies (PTA basic) was significantly greater in affected ears when compared with unaffected ears. The conductance tympanogram at 2 kHz revealed a statistically significantly greater G width of 2 kHz in the affected ears when compared to both unaffected and control ears, while control ears had a statistically significant lesser G width of 2 kHz compared to both the other two groups. MFT, and specifically G width at 2 kHz, could be an important tool in the diagnosis of MD.

OBJECTIVE
This systematic review and meta-analysis investigates the effects optokinetic stimulation in people with vestibular disorders, with a specific focus on people with visually induced dizziness.
DATA SOURCES
A systematic review was conducted using three electronic databases, CINAHL, PubMed and Physiotherapy Evidence Database (PEDro), from 2000 up to February 2024.
REVIEW METHODS
Randomised controlled trials were included, which compared: (a) adults above 18 years old with vestibular disorders, (b) the study evaluated interventions using optokinetic stimulation, (c) the intervention was compared with usual care; placebo or to no intervention, (d) the study included at least one outcome measure evaluating vestibular symptoms and (e) published in English. The methodological quality of the included studies was assessed using the PEDro scale and PROSPERO's registration number ID: CRD42021273382).
RESULTS
Eleven randomised control trials, reported in 12 records, fulfilled the inclusion criteria. All of the studies were considered to have 'good' methodological quality according to the PEDro scale. All studies showed significant improvement in vestibular symptoms in both the intervention and control groups. A meta-analysis performed on six of the records found a preference towards the addition of OKS to conventional vestibular rehabilitation helped to further reduce dizziness symptoms for patients, but the results were not statistically significant.
CONCLUSION
No optimal duration or frequency for OKS has been determined. The addition of OKS to conventional vestibular rehabilitation may be beneficial in further improving vestibular symptoms in patients with dizziness. OKS could help to improve enjoyment and adherence to vestibular rehabilitation.

Review
OBJECTIVES
To analyse the effectiveness of optokinetic stimulation (OKS) for improving symptoms and function in patients with vestibular and balance disorders.
METHODS
PubMed (MEDLINE), SCOPUS, Web of Science (WOS), CINAHL Complete, and PEDro databases were searched to identify randomized controlled trials (RCTs) that included patients with vestibular and balance disorders and compared the effects of OKS versus other interventions or no intervention on subjective or objective functional outcomes. Data were analysed by the standardized mean difference (SMD) and its 95% confidence interval.
RESULTS
A total of 10 studies were selected including 468 patients, 177 of whom received OKS. There were no significant differences in scores on the Dizziness Handicap Inventory (DHI) (SMD = 0.02; 95% CI - 0.18 to 0.23; p = 0.83) or the visual analogue scale (VAS) for vertigo (SMD = 0.16; 95% CI - 1.25 to 1.58; p = 0.82). However, there were statistically significant differences in the timed up and go (TUG) test, with a large effect (SMD = - 1.13; 95% CI -2 to - 0.28; p = 0.009), and in the sensory organization test (SOT), with a medium effect (SMD = - 0.7; 95% CI - 1.21 to - 0.19; p = 0.007). Subgroup analysis showed significant effects of OKS on VAS (p = 0.017), TUG (p = 0.009) and SOT (p = 0.001) only in patients with balance disorders without vestibular disease (p > 0.05).
CONCLUSIONS
OKS may improve dizziness intensity measured with VAS or dynamic balance measured whit TUG and SOT in patients with balance disorders not due to vestibular disease. The quality of the evidence was low or very low due to the small number of included studies.

Review
Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder characterized by episodic vertigo. BPPV primarily affects older adults. Thus, understanding the potential relationship between BPPV and osteoporosis is clinically important. We performed a systematic search of MEDLINE (PubMed), Embase, and Cochrane Library databases for studies on the risk of osteoporosis between BPPV (+) and BPPV (-) groups up until 17 April 2023. We compared osteoporosis prevalence between groups and performed subgroup analyses for male, female, and older patients (aged ≥ 55 years). The 12 studies included 32,460 patients with BPPV and 476,304 controls. Pooled analysis showed that the BPPV (+) group had a significantly higher osteoporosis risk than the control group (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.45-2.06; < 0.01). Subgroup analyses also presented similar trends as male (OR, 2.41; 95% CI, 1.18-4.90; = 0.02), female (OR, 2.14; 95% CI, 1.57-2.92; < 0.001), and older patient subgroups (OR, 1.91; 95% CI, 1.47-2.49; < 0.01) showed a higher osteoporosis risk in the BPPV (+) group than in the control group. This meta-analysis supports the hypothesis that patients with BPPV have a higher osteoporosis prevalence than those without.

Review
PURPOSE
This review aimed to examine the effects of the Semont maneuver on posterior canal benign paroxysmal positional vertigo (BPPV).
METHODS
PubMed, PEDro, SCOPUS, REHABDATA, EMBASE, and Web of Science were searched comprehensively from inception to January 2024. The Physiotherapy Evidence Database (PEDro) scale was employed to evaluate the quality of the selected studies.
RESULTS
In total, 18 randomized controlled trials met the eligibility criteria. A total of 2237 participants with BPPV (mean age = 58.10 years) were included in this review. Among them, 37.5% were males, and 58% presented with right-sided BPPV. The included studies ranked from 5 to 9 out of 10 (Median = 7), suggesting good to excellent quality on the PEDro scale. The available literature revealed that the Semont maneuver is effective in improving posterior canal BPPV symptoms.
CONCLUSION
The Semont maneuver is considered a standard option for treating posterior canal BPPV, with a high success rate of around 80%. It is suggested as the primary option for managing posterior canal BPPV in individuals who complain of cervical or lumbar problems, severe cardiac or respiratory conditions. Further studies are strongly needed to understand the long-term effects of the Semont maneuver and to identify the recurrence rate.

To systematically synthesize published literature on somatoform complaints as psychological factors in vertigo/dizziness to determine the characteristics of comorbidities, relationships and causality. Following PRISMA guidelines, systematic searches of PubMed, WOS, and Cochrane Library databases and manual follow-up reference searches were performed for articles published in English up to 2021. All original research studies and retrospective or prospective studies focusing on the relationship between vertigo/dizziness and somatoform complaints/somatization were systematically retrieved. Studies that did not include data on the association between somatoform complaints/somatization and vertigo/dizziness were excluded, as were reviews, comments, case reports, editorials, letters, and practice guidelines. Extracted data included research type, number of participants, assessment tools for vertigo/dizziness and somatoform complaints/somatization, statistical methods, and the main results. The quality of included studies was evaluated. Records identified through database searching = 1238. After removing duplicates and unrelated articles based on abstract and title search, 155 articles recorded as relevant. Except for the 5 articles, title and abstract of all records screened and 88 of them excluded. Critically evaluating those full texts, 28 studies included. The present study highlights the relationship between the vertigo/dizziness and somatoform complaints/somatization. It is determined that somatoform complaints of the individuals suffering from vertigo/dizziness is highly prevelant and some other factor such as personality characteristics or accompanying psychopathology have affect on the prevelance. The main results of all reviewed studies emphasize the requirement for assessment and intervention of vertigo/dizziness, in collaboration with the department of psychiatry.

Review
Hyperostosis frontalis interna (HFI) is a condition defined as abnormal bone growth on the posterior aspect of the frontal bone. Despite uncertainties regarding its etiology and prognosis, clinicians typically consider HFI a benign pathology. There are no studies organizing all the possible manifestations of the disease. The present study aims to organize all the clinical manifestations of HFI within the current case report/series literature. A blinded PRISMA-guided search of HFI case reports and case series yielded 43 relevant articles and provided 110 patients for analysis. The symptoms presenting alongside HFI were extracted and tabulated. We found high-frequency clinical manifestations of HFI (>20% of patients) to include headaches, obesity, vertigo/dizziness symptoms, cognitive decline, and depression. An additional 15 symptoms were tabulated at frequencies found to be less than 20%. Based on our analysis, we suggest the constellation of high-frequency symptoms can offer a more comprehensive clinical picture of symptomatic HFI which may be valuable to consider for clinicians and future researchers in the field of HFI.

Meta-Analysis Review
BACKGROUND/INTRODUCTION
In patients with acute vestibular syndrome (AVS), differentiating between stroke and nonstroke causes is challenging in the emergency department (ED). Correct diagnosis of vertigo etiology is essential for early optimum treatment and disposition.
OBJECTIVES
The aim of this systematic review and meta-analysis was to summarize the published evidence on the potential of blood biomarkers in the diagnosis and differentiation of peripheral from central causes of AVS.
METHODS
A literature search was conducted for studies published until January 1, 2023, in PubMed, Ovid Medline, and EMBASE databases analyzing biomarkers for the differentiation between central and peripheral AVS. The Quality Assessment of Diagnostic Accuracy Studies questionnaire 2 was used for quality assessment. Pooled standardized mean difference and 95% confidence intervals were calculated if a biomarker was reported in two or more studies. Heterogeneity among included studies was investigated using the I metric.
RESULTS
A total of 17 studies with 859 central and 4844 peripheral causes of acute dizziness or vertigo, and analysis of 61 biomarkers were included. The general laboratory markers creatinine, blood urea nitrogen, albumin, C-reactive protein, glucose, HbA1c, leukocyte counts, and neutrophil counts and the brain-derived biomarkers copeptin, S100 calcium-binding protein β (S100β), and neuron-specific enolase (NSE) significantly differentiated central from peripheral causes of AVS.
CONCLUSIONS
This systematic review and meta-analysis highlights the potential of generalized inflammatory markers and brain-specific blood protein markers of NSE and S100β as diagnostic biomarkers for central from peripheral differentiation in AVS. These results, as a complement to clinical characteristics, provide guidance for future large-scale diagnostic research, in this challenging ED patient population.

Meta-Analysis
BACKGROUND
Stereotactic radiosurgery (SRS) is a well-established treatment option for Koos stage I-III vestibular schwannomas (VS), often used as the first line of treatment or after subtotal resection. However, the optimal treatment for Koos-IV VS remains unclear. Therefore, our study aimed to evaluate the effectiveness of SRS as a primary treatment for large VS classified as Koos-IV.
METHODS
A systematic search was performed on December 28th, 2022, based on PubMed, Web of Science, and Scopus according to the PRISMA statement. The review was updated on September 7th, 2023. The risk of bias was assessed using the NIH Quality Assessment Tool. The R software (ver. 4.3.2) was used for all quantitative analyses and preparation of the forest plots. Publication bias and sensitivity analysis were performed to evaluate the reliability of the obtained results.
RESULTS
Among 2941 screened records, ten studies (1398 patients) have been included in quantitative synthesis. The overall tumor control rate was 90.7% (95%CI 86.3-94.4). Kaplan-Meier estimates of tumor control at 2, 6, and 10 years were 96.0% (95% CI 92.9-97.6%), 88.8% (95% CI 86.9-89.8%), and 84.5% (95% CI, 81.2-85.8%), respectively. The overall hearing preservation rate was 56.5% (95%CI 37-75.1). Kaplan-Meier estimates of hearing preservation rate at 2, 6, and 10 years were 77.1% (95% CI 67.9-82.5%), 53.5% (95% CI 44.2-58.5%), and 38.1% (95% CI 23.4-40.7%), respectively. The overall facial nerve preservation rate was 100% (95%CI 99.9-100.0). The overall trigeminal neuropathy rate reached 5.7% (95%CI 2.9-9.2). The overall rate of new-onset hydrocephalus was 5.6% (95%CI 3-9). The overall rates of worsening or new-onset tinnitus and vertigo were 6.8% (95%CI 4.2-10.0) and 9.1% (95%CI 2.1-19.6) respectively. No publication bias was detected according to the used methods.
CONCLUSIONS
Our systematic review and meta-analysis demonstrated a high overall tumor control rate, excellent facial nerve preservation, and low incidence of new-onset or worsened tinnitus and vertigo. However, several drawbacks associated with SRS should be noted, such as the presence of post-SRS hydrocephalus risk, mediocre long-term hearing preservation, and the lack of immediate tumor decompression. Nevertheless, the use of SRS may be beneficial in appropriately selected cases of Koos-IV VS. Moreover, further prospective studies directly comparing SRS with surgery are necessary to determine the optimal treatment for large VS and verify our results on a higher level of evidence.

INTRODUCTION
To date, no systematic review or meta-analysis has critically evaluated the relevance of using optokinetic after-nystagmus (OKAN) in diagnosis of vestibular disorders. To assess the role of OKAN in diagnosis of vestibular disorders, the OKAN time constant (TC) between patients with vestibular disorders and healthy participants will be compared.
METHODS
Automated search strategies were carried out in the Embase, Medline PubMed, Web of Science, and Scopus databases from inception to December 2023. The following inclusion criteria were applied: (1) evaluation of OKAN in individuals with vestibular disorders, (2) clinical trials, and (3) inclusion of healthy individuals as the control group. Exclusion criteria were: (1) animal studies, (2) non-clinical trial study designs, (3) assessment of non-vestibular disorders, (4) no examination of OKAN TC, (5) only examination of healthy participants, (6) studies published in a language other than English, (7) no healthy participants as control group, (8) case reports, and (9) only abstract available. The random-effects model was used to pool the data. The Joanna Briggs Institute (JBI) Critical Appraisal Tools was used to assess the risk of bias. The quality assessment was performed with the aid of the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, provided by NHLBI. The PRISMA guidelines were used as reporting guidelines. The main outcome of this study was the between-group mean difference (MDbetween) in OKAN TC and its 95% confidence interval between patients with vestibular disorders and healthy participants.
RESULTS
Seven out of 244 screened articles were included that studied 289 participants. The overall mean difference (MD = -7.08) with a 95% CI of [-10.18; -3.97] was significant ( = 0.014). The heterogeneity was significant ( = 0.02). Quality assessment was generally good (76%). The risk of bias was low in five studies and moderate in two studies.
CONCLUSION
The results demonstrate that OKAN TC is significantly shorter in patients with vestibular disorders compared to healthy controls. This finding is important for future research, particularly with the emergence of novel clinical tools and diagnostic syndromes.
