Individualized repositioning with a mechanical rotational chair facilitates successful treatment of patients with very retractable benign paroxysmal positional vertigo. Am J Otolaryngol 2024; 45:104241. [PMID: 38574512 DOI: 10.1016/j.amjoto.2024.104241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 02/22/2024] [Accepted: 02/24/2024] [Indexed: 04/06/2024]
Abstract
BACKGROUND About 12.5 % of patients diagnosed with benign paroxysmal positional vertigo (BPPV), experience persistent BPPV where it is unknown why some BPPV cases are very refractory (vrBPPV) to treatment. OBJECTIVES The primary objective was to investigate if patients with vrBPPV could be successfully treated with a mechanical rotation chair (MRC) adjusted to the exact vertical semicircular canal (SCC) angles of the individual patient. Secondary endpoint was to determine if inner ear anomalies were predominant in these patients. METHODS This prospective clinical trial included 20 patients (main group) who underwent computed tomography (CT) with measurements of the bony island and the width between the SCC walls of the posterior leg of the lateral SCCs. The inter-SCC angles, the angles between the sagittal plane and the vertical SCCs were compared to the presumed mean standard angles of the SCCs. Of these, 14 patients (subgroup) underwent individualized treatment with the Rotundum® repositioning chair according to their measured SCC angles. RESULTS All measured SCC angles differed significantly (p < 0.05) from the presumed mean standard SCC angles, except the angle between the sagittal plane and the left posterior SCC (p-SCC). Three out of 14 patients experienced subjective and objective remission after treatment with this MRC. Six out of 14 patients experienced either subjective remission or objective remission. CONCLUSIONS Patients with vrBPPV have vertical SCC angles that differ significantly from the presumed mean standard SCC angles. Individualized treatment with this MRC successfully treated 21.4 % of the patients with vrBPPV and provided subjective relief for 42.9 %.

Treatment efficacy of repositioning maneuvers in multiple canal benign paroxysmal positional vertigo: a systematic review and meta-analysis. Front Neurol 2023; 14:1288150. [PMID: 38020643 PMCID: PMC10658715 DOI: 10.3389/fneur.2023.1288150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Accepted: 10/20/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Benign paroxysmal positional vertigo (BPPV) involving the posterior canal is more common than other canals; however, simultaneous involvement of multiple canals can be seen up to 20% of all BPPV cases. The diagnosis and management of multiple canal BPPV can be quite challenging due to the complexity of findings. Therefore, this systematic review and meta-analysis aimed at unveiling the most effective repositioning strategy for the treatment of multiple canal BPPV. Methods A literature search through PubMed, Scopus, and Web of Science databases was conducted using search terms such as BPPV, multiple canals, bilateral BPPV, repositioning maneuvers etc. After duplicate removal, the retained articles underwent various stages of elimination by two independent reviewers, and a third reviewer resolved the discrepancy between them. Results A total of 22 articles were included in the systematic review. These publications documented 5,196 patients diagnosed with BPPV, of which 513 had multiple canal BPPV. Of 295 individuals with multiple canal BPPV, 58.9% were effectively treated in 1 session, whereas 18.3 and 4.4% achieved a symptom-free state after two and three sessions, respectively. Failure of treatment using repositioning maneuvers was found in 18.4%. Possible implications This study offers insight into the real world of BPPV management in single and multiple canal BPPV. It is evident that repositioning maneuvers provide rapid and long-lasting relief of BPPV in most single canal BPPV patients; however, multiple canal BPPV often requires repeated treatment, and the risk of recurrence is higher in this variety than the single canal BPPV.

[PMID: 33776883 PMCID: PMC7988206 DOI: 10.3389/fneur.2021.618269] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 02/08/2021] [Indexed: 11/25/2022] Open
Abstract
Objective: To define diagnostic VNG features in anterior canal BPPV during positional testing (Dix-Hallpike, supine head hanging, and McClure Pagnini tests). Study Design: A retrospective study of patients diagnosed with anterior canal BPPV across four referral centers in New Delhi, Kochi, Bangalore, and Dubai. Subjects and Methods: Clinical records of 13 patients with AC BPPV out of 1,350 cases, during a 3-years period, were reviewed and analyzed by four specialists. Results: Four patients had positional down beating nystagmus with symptoms of vertigo during the bilateral DHP maneuver. Seven cases had positional down beating nystagmus only on one side of DHP. Typical down beating nystagmus was seen in 10 out of 13 cases during the straight head hanging maneuver. Down beating torsional nystagmus was seen in 6 out of 13 cases. Down beating with horizontal nystagmus was seen in three cases (in DHP and MCP mainly) while pure down beating nystagmus during SHH was only seen in four cases. Conclusion: We conclude that anterior canal BPPV is a rare but definite entity. It may not be apparent on positional testing the first time, so repeated testing may be needed. The most consistent diagnostic maneuver is SHH though there were patients in which findings could only be elicited using DHP testing. We recommend a testing protocol that includes DHP testing on both sides and SHH. MCP testing may also evoke DBN with or without the torsional component. Reversal of nystagmus on reversal of testing position is unusual but can occur. The Yacovino maneuver is effective in resolving AC BPPV. We also propose a hypothesis that explains why DHP testing is sensitive to AC BPPV on either side, whereas MCP lateral position on one side is only sensitive to AC BPPV on one side. We have explained a possible role for the McClure Pagnini test in side determination and therapeutic implications.

Abstract
BACKGROUND AND OBJECTIVE Benign paroxysmal positional vertigo (BPPV) is the most common vertigo of labyrinthine origin, its social and healthcare impact is remarkable. It has recently been shown that single session treatment is as safe and effective as weekly treatment, which could have impact on direct and indirect costs related to the disease. The objective of this study is to determine whether single session treatment of unilateral posterior canal BPPV canalolithiasis is more efficient than conventional treatment. MATERIALS AND METHODS A prospective randomized controlled trial was performed in 53 consecutive patients diagnosed with unilateral posterior canal BPPV canalolithiasis previously untreated: 26 patients were assigned to single session treatment and 27 patients to weekly treatment. Average and total cost of care, consultation time and the impact in terms of temporary disability and loss of productivity for the company due to patients' medical visits were compared. RESULTS Average and total cost of care and loss of productivity for the company due to patients' medical visits were significantly lower in the single session group. Consultation time was also better in this group when travelling time was considered. CONCLUSIONS The single session protocol is fast, effective and reduces direct and indirect cost of care related to disease justifying high resolution consultations.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder affecting about 20% of dizzy patients. Early diagnosis and treatment can improve the quality of life for patients. OBJECTIVE We reviewed the classifications of different subtypes of benign paroxysmal positional vertigo and the problems we encountered using the diagnostic criteria of the Bárány Society. METHODS Both the Dix-Hallpike maneuver and supine roll test were performed on 568 patients, and diagnoses were made based on patient history and the type of provoked nystagmus (if any). Next, the numbers of patients with each subtype and other parameters, including age and sex, were analyzed. RESULTS Posterior semicircular canal BPPV (pc-BPPV) accounted for the largest proportion, followed by horizontal semicircular canal BPPV (hc-BPPV). Both anterior canal BPPV and multiple canal lithiasis BPPV were rare, and no patient was diagnosed with cupulolithiasis of the posterior canal. CONCLUSIONS pc-BPPV, hc-BPPV, and cupulolithiasis of the horizontal canal (hc-BPPV-cu) were the three major subtypes that could be definitively diagnosed, whereas the diagnoses of possible benign paroxysmal positional vertigo (pBPPV) and probable benign paroxysmal positional vertigo [spontaneously resolved] (pBPPVsr) require further investigation, with special attention being paid to appropriate differentiation and repositioning maneuvers.

Abstract
Objective: Direction-changing positional nystagmus (DCPN) had been observed as persistent horizontal apogeotropic and was considered as “cupulolithiasis or heavy cupula. ” Recently, the concept of “light cupula” exhibiting persistent geotropic DCPN has been introduced. However, the light cupula is not systematically described, while the identification and diagnosis of “light cupula” should be improved. Here we investigated the underlying characteristics and therapeutic options designed to the “light” and “heavy” cupula, respectively; and summarized the clinical characteristics and therapeutic effect in the two groups. Methods: A total of 359 cases with vertigo and bilateral DCPN were found in the supine roll test. Only 25 patients with persistent DCPN were enrolled and followed up. According to the direction of nystagmus, we further divided the patients into “heavy cupula” (apogeotropic) and “light cupula” (geotropic) groups. We compared the incidence, characteristics of nystagmus and the efficacy of repositioning maneuver in the two groups. Results: Nine patients with persistent horizontal geotropic DCPN were confirmed as “light cupula,” other 16 patients with persistent horizontal ageotropic DCPN were confirmed as heavy cupula. All 25 patients had null plane; the mean value and standard deviation of the null plane in light cupula and heavy cupula was 25.67 ± 9.31° and 27.06 ± 6.29°, respectively. The mean value and standard deviation of the termination plane in light cupula was 28.78 ± 10.00°, and 30.25 ± 6.53° in heavy cupula. There was no statistical significance between the two groups. We found that the direction of evoked nystagmus in the supine position was toward the intact side in light cupula, while in heavy cupula, it was toward the lesion side. The null plane appeared on the lesion side. For light cupula patients, the effect was not obvious at Day-7 after the treatment, however, treatment for most heavy cupula patients were effective. All patients recovered after 30 days of treatment. Conclusion: The null plane is crucial in determining the lesion side for light or heavy cupula. Although the short-term therapeutic effect of the light cupula is not as promising as the effect seen in heavy cupula, the long-term prognosis in both groups is comparable; with all patients recovered after 30 days of treatment. Study design: This is a retrospective cohort study.

Association Between Serum Uric Acid Levels and Benign Paroxysmal Positional Vertigo: A Systematic Review and Meta-Analysis of Observational Studies. Front Neurol 2019; 10:91.

Abstract
Objective: The objective of the present study was to meta-analyze relevant literature to gain a comprehensive understanding of the potential relationship between serum uric acid levels and risk of benign paroxysmal positional vertigo (BPPV). Methods: The databases of PubMed, Web of Science, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed were systematically searched for observational case-control studies of the association between BPPV and serum uric acid levels published up to October 2018. Data from eligible studies were meta-analyzed using Stata 12.0. Results: A total of 12 studies were included in the analysis. There was a strong tendency for serum uric acid levels to be associated with risk of BPPV among studies conducted in China (OR 0.69, 95%CI 0.01–1.40, p = 0.053), but not among studies outside China (OR 1.07, 95%CI 1.08–3.22, p = 0.33). Across all studies, serum uric acid level was significantly higher among individuals with BPPV than among controls (OR 0.78, 95%CI 0.15–1.41, p = 0.015), yet it did not independently predict risk of the disorder (OR 1.003, 95%CI 0.995–1.012, p = 0.471). Conclusion: The available evidence suggests that BPPV is associated with elevated levels of serum uric acid, but these levels may not be an independent risk factor of BPPV.
