“…The range of BPPV recurrence rates was 18–67% in six prospective studies with at least 2 years of follow-up and showed an average BPPV recurrence rate of 34%. Recurrence rates of two of these studies, with an average follow-up period of 10 years, still varied more than 30% ( 16 , 34 – 38 ). However, it seems to be consistent throughout the literature, including this study, that the majority of BPPV recurrences happen within the first six months following successful repositioning.…”

“…Age and sex were not significantly associated with higher recurrence rates, though female sex had a tendency (p < 0.1). Existing literature find contradictory results in regard to sex and age, as some find female sex and advanced age as risk factors (36,39,40), while others do not (34,37,41,42). Other risk factors include hypertension, hyperlipidemia, vitamin D deficiency and osteoporosis (34,41,42), which are also known risk factors of BPPV occurrence (43).…”

Seven years of experience with treatment of benign paroxysmal positional vertigo with a mechanical rotational chair

BackgroundThroughout the last decade, several mechanical rotational chairs have been developed for diagnostics and treatment of patients with a typical case history of benign paroxysmal positional vertigo. Sparse evidence, however, exists in terms of diagnostic accuracy and treatment efficiency with these mechanical rotational chairs. Also, recommendations for optimal use of these chairs are yet to be determined.ObjectivePrimary objective was to evaluate overall treatment of benign paroxysmal positional vertigo with a mechanical rotational chair and secondary objectives included description of patient- and BPPV characteristics, determination of subjective and objective outcomes, as well as analyzation of recurrence- and recurrence-related risk factors following successful treatment.MethodsRetrospective cohort study with 635 patients diagnosed with benign paroxysmal positional vertigo and treated by means of a mechanical rotational chair during a 7-year period from 2014 to 2021 at a tertiary University hospital. Patient- and disease-specific characteristics, treatment and recurrence data were collected through reviewing of patient records.ResultsThe mean number of required treatments was 2.7 when accounting for a six percent treatment failure rate (defined as a need of more than 10 treatments), and 3.7 when not. Bilateral mono-canal affection required 3.8 treatments, unilateral multi-canal 3.5 treatments, and the combination of bilateral and multi-canal affection 5.2 treatments. All these scenarios were associated with significantly higher numbers of required treatments when compared to unilateral mono-canal affection, which required 1.9 treatments. The overall recurrence rate was 25.4 percent.ConclusionA mechanical rotational chair provides successful treatment of benign paroxysmal positional vertigo. Mechanical rotational chairs should primarily be reserved for the treatment of retractable and atypical benign paroxysmal positional vertigo patients. Many aspects of the optimal use of these chairs still require elaborative assessment.

“…BPPV most commonly involves the posterior semicircular canal (PSCC), followed by the lateral semicircular canal (LSCC); however, several recent studies have shown that LSCC BPPV might be more common than reported previously. [1][2][3][4] Because spontaneous remission often occurs in BPPV, [5][6][7] the time interval from onset of vertigo to initial evaluation should be considered when estimating the true incidence of BPPV subtypes. Additionally, patientperceived subjective vertigo may vary among individuals with BPPV, which can thus affect hospital use behavior.…”

The present study investigated the impact of coronavirus disease 2019 (COVID-19) pandemic on benign paroxysmal positional vertigo (BPPV). Patients and Methods:The medical records of BPPV patients who were evaluated in the outpatient department (OPD) and emergency room (ER) during (435 patients) and before (517 patients) the COVID-19 pandemic were retrospectively reviewed. Dix-Hallpike and supine head-roll tests were used to classify the subtype of BPPV as posterior semicircular canal (PSCC), geotropic lateral semicircular canal (geotropic LSCC), or apogeotropic lateral semicircular canal (apogeotropic LSCC) BPPV. Results: More patients with PSCC BPPV were diagnosed at the OPD compared with those who were diagnosed at the ER both before and during the COVID-19 pandemic; however, more patients with LSCC BPPV were diagnosed at the ER compared with those who were diagnosed at the OPD during the same periods. The mean time interval between vertigo onset and initial evaluation was remarkably longer during the pandemic in patients with PSCC BPPV. Conclusion:This study demonstrated that the incidences of BPPV subtypes according to hospital visit type were not significantly different before and during the COVID-19 pandemic. Because hospital visits were delayed in patients with PSCC BPPV during the COVID-19 pandemic, telemedicine or e-health could be suitable alternatives to face-to-face medical care for these patients.

ObjectiveTo evaluate the effect of vitamin D supplementation on the recurrence rate of benign paroxysmal positional vertigo (BPPV).MethodsA single‐center, prospective, double‐blind, placebo‐controlled, parallel‐group randomized controlled trial was conducted between November 2018 and May 2020. After successful treatment with canalith repositioning maneuvers, patients diagnosed with BPPV were randomized to either the vitamin D (n = 20) or placebo (n = 18) group. Only patients with serum vitamin D levels <20 ng mL−1 were included. The vitamin D group received 7000 IU of vitamin D weekly for a year, while the placebo group received a matching placebo drug. The final endpoint was the BPPV recurrence rate and correlation with serum vitamin D levels after 6 and 12 months in both groups.ResultsAmong 38 patients, 37 were followed up for 6 months and 30 for 12 months. Significantly higher serum vitamin D levels were observed in the vitamin D group compared to the placebo group at both the 6‐month and 1‐year follow‐ups (p < .001 at each timepoint). The recurrence rate was lower in the vitamin D group than in the placebo group after 6 months (p = .008) and 1 year (p = .003).ConclusionVitamin D supplementation, in the absence of calcium, may be beneficial for patients prone to recurrent BPPV episodes, particularly when serum vitamin D levels are suboptimal (PRE20181024‐001, Clinical Research Information Service, South Korea).Level of Evidence1b.
