Contralateral incipient posterior canal benign positional paroxysmal vertigo: complication after Epley maneuver

Background: Particle repositioning procedures give consistent results for the treatment of benign positional paroxysmal vertigo (BPPV). However, little consideration has been given to the possibilities of bilateral disease. Objective/Hypothesis: To report contralateral symptoms and signs suggestive of revealed or incipient BPPV as a complication of Epley maneuver. Study Design: A prospective cohort of 198 cases over a period of 11 years. Results: Ten (5.0%) developed contralateral symptoms and signs suggestive of revealed or incipient posterior canal BPPV within 2 weeks of treatment. Conclusion: This novel observation has not been previously described and may influence the strategy for future management of patients with BPPV. Particle repositioning maneuvers for the previously asymptomatic contralateral ear may need to be considered in a subset of patients with posterior canal BPPV who suffer contralateral symptoms after undergoing treatment for the original ear.

Double-blind randomized controlled trial on efficacy of cupulolith repositioning maneuver for treatment of apogeotropic horizontal canal benign paroxysmal positional vertigo

Abstract

Backgrounds: Although various therapeutic maneuvers have been proposed, it is still unclear which maneuver is better to treat apogeotropic horizontal canal benign paroxysmal positional vertigo (HC-BPPV).

Objectives: This study aimed to assess the therapeutic efficacy of the cupulolith repositioning maneuver (CuRM) in apogeotropic HC-BPPV in comparison with the therapeutic head-shaking maneuver and modified Lempert maneuver.

Materials and Method: This is double-blind randomized prospective study. Forty-nine consecutive patients diagnosed with apogeotropic HC-BPPV were allocated randomly to CuRM (n?=?18), therapeutic head-shaking (n?=?16), or modified Lempert maneuver (n?=?15). The presence of nystagmus and vertigo on positional testing were evaluated at 30?min, on 1?day, and 1?week after treatment.

Results: There were no significant differences in any clinical characteristics between the three groups at randomization. After a single trial of therapeutic maneuvers on the initial visit day, the CuRM (38.9%) and therapeutic head shaking maneuver (12.5%) did not show differences compared to modified Lempert maneuver (33.3%). The therapeutic effects on the 2nd day and at 1?week after treatment also did not differ between the three groups.

Conclusions: Although the CuRM is theoretically considered to be a better therapeutic method, the therapeutic efficacy of CuRM was not statistically different compared to the other two maneuvers.     

The Epley maneuver for the treatment of benign paroxysmal positional vertigo

In recent years, different forms of physical therapy have been proposed for the treatment of benign paroxysmal positional vertigo (BPPV). These mainly consist of maneuvers aiming to reposition and disperse free-floating endolymph particles in the posterior semicircular canal. We report our experience with one of these procedures, the Epley maneuver (EM), in treating 30 cases of BPPV. Twenty-six patients (87%) were cured, while four (13%) did not respond to treatment. These results are similar to those reported in the literature for the EM and the Sémont maneuver.     

Management of 210 patients with benign paroxysmal positional vertigo: AMC protocol and outcomes

Conclusion: Benign paroxysmal positional vertigo (BPPV) could be treated with specific maneuvers for the involved canals. Management on a daily basis gave earlier relief than weekly treatment, especially in apogeotropic BPPV. Apogeotropic and multi-canal BPPVs were related to the increased numbers of follow-ups and trauma was related to the increased recurrence. Objective: We aimed to report the short-term outcomes of our protocol for BPPV and evaluate the factors influencing the results and recurrence. Methods: In 210 BPPV patients, posterior semicircular canal (PSCC), geotropic and apogeotropic lateral canal BPPVs were treated with the Epley maneuver, barbecue maneuver, and barbecue maneuver after head-shaking. The total number of follow-ups needed to have no provoked nystagmus, success rates at 1 week and 1 month, and factors for repeated maneuvers or recurrence were identified. Results: Apogeotropic and multi-canal BPPV needed more follow-ups than PSCC BPPV. Multi-canal BPPV showed a significantly lower 1-week success rate than other types. Anterior and multi-canal BPPV showed significantly lower 1-month success rates than other types. The 1-week success rates for PSCC and geotropic and apogeotropic BPPV in patients followed up on a daily basis were higher than those in patients with weekly follow-up and the difference was significant only in apogeotropic BPPV. The overall 1-year recurrence rate was 16% and higher recurrence rate was related to trauma.

目的 观察后半规管耳石症（BPPV）患者经手法复位成功后,其头晕发生率及持续时间。方法 2009～2011年门诊确诊单侧后半规管BPPV手法复位成功患者418例,分成老年组（≥60岁）137例、青年组（<60岁）281例,分别观察两组头晕发生率及持续时间。结果 老年组头晕发生率45.3%（62/137）,青年组27%（76/281）,两组间差异有统计学意义（P<0.01）;头晕平均持续时间老年组（14.6±4.4）d,青年组（8.9±4.7）d,两组间差异有统计学意义（P<0.01）;老年组中女性头晕发生率43.3%（39/90）,男性48.9%（23/47）,两组间差异无统计学意义（P>0.05）;老年组中女性头晕平均持续时间（15.7±5.3）d,男性（14.7±4.6）d,两组间差异无统计学意义（P>0.05）。结论 老年BPPV患者复位治疗成功后头晕发生率明显高于青年组,头晕持续时间明显长于青年组;老年组头晕发生率及持续时间与性别无关。     

Variables affecting treatment in benign paroxysmal positional vertigo

OBJECTIVE: To identify variables affecting outcome in patients with benign paroxysmal positional vertigo (BPPV) treated with canalith repositioning maneuvers. STUDY DESIGN: Retrospective review of patients at a tertiary vestibular rehabilitation center. METHODS: Variables identified for statistical analysis included method of diagnosis, age, sex, onset association with trauma, semicircular canal involvement, presence of bilateral disease, treatment visits, and cycles of canalith repositioning maneuvers per treatment visit. Multivariate statistical analysis using Pearson chi2, likelihood ratio, linear-by-linear association, and cross-tabulation tests were performed. RESULTS: Two hundred fifty-nine patients with BPPV who received treatment were identified from 1996 to 1998. Average follow-up time was 16.9 months. 74.8% required one treatment visit, 19.0% required a second treatment visit, and 98.4% were successfully treated after three treatment visits. The remainder required up to seven treatment visits for relief of symptoms. Variables affecting the number of treatment visits included bilateral disease or location of disease other than in the posterior semicircular canal. Patient age, sex, method of diagnosis, and onset association with trauma had no statistically significant impact. CONCLUSION: Patients with benign paroxysmal positional vertigo not located in a single posterior semicircular canal are more likely to require multiple visits for canalith repositioning.     

Effects of Semont maneuver on benign paroxysmal positional vertigo: a meta-analysis

Background: Benign paroxysmal positional vertigo (BPPV) is the most common type of peripheral vertigo. This study aimed to evaluate the effects of the Semont maneuver (SM) for BPPV treatment, compared with other methods.

Methods: Studies were selected in relevant databases under pre-defined criteria up to June 2015. The Cochrane evaluation system was used to assess the quality of the studies. Effect size was indicated as a risk-ratio (RR) with corresponding 95% confidential interval (CI). Statistical analysis was conducted under a randomized- or fixed-effects model. Sub-group analysis was performed.

Results: Ten studies were included in the meta-analysis. All of the studies presented a low attrition bias, but a high selection and reporting bias. SM had a much higher recovery rate (SM vs no treatment: RR?=?2.60, 95% CI?=?1.97–3.44, p?p?p?Conclusion: SM is as effective as EM and BDE for BPPV treatment.

Canalith repositioning for benign paroxysmal positional vertigo: a randomized, controlled trial

We assessed the efficacy of the canalith repositioning maneuver by comparing it with no treatment in a population of patients with benign paroxysmal positional vertigo (BPPV). In this randomized, controlled, 6-month efficacy trial, outcomes were measured subjectively by patients' reports of symptom status and objectively by Hallpike testing. During the first month of the study, the treated group experienced significantly better outcomes than did the control group, but this trend was not sustained at 3 and 6 months.     

A comparative study of two methods for treatment of benign paroxysmal positional vertigo in the emergency department

IntroductionPosterior canal benign paroxysmal positional vertigo (PC-BPPV) is considered the most common cause of peripheral vertigo in the emergency department (ED). Although the canalith repositioning maneuver (CRM) is the standard of care, the most effective method to deliver it in the ED has been poorly studied.ObjectiveTo compare two protocols of the Epley maneuver for the treatment of PC-BPPV.Patients and methodsWe prospectively recruited 101 patients with unilateral PC-BPPV on physical examination, randomizing them to either a single Epley maneuver (EM) (n = 46) or multiple maneuvers (n = 55) on the same visit. Measured outcomes included presence/absence of positional nystagmus, resolution of vertigo, and score on the dizziness handicap inventory (DHI) at follow-up evaluations. The DHI was stratified into mild (≤30) and moderate-severe (>30).ResultsNormalization of the Dix-Hallpike maneuver at day 5 was observed in 38% of the single EM group and 44.4% in the multiple EM group (p = 0.62). The DHI showed reduction from 42.2 (SD 18.4) to 31.9 (SD 23.7) in the single EM group and from 43.7 (SD 22.9) to 33.5 (SD 21.5) in the multiple EM group (p = 0.06). A higher number of patients improved from moderate-severe to mild DHI (p = 0.03) in the single EM group compared to the multi-EM group (p = 0.23).ConclusionThere was no statistically significant difference between performing a single EM versus multiple EMs for treatment of PC-BPPV in the emergency department. The single EM approach is associated with shorter physical contact between patients and examiner, which is logically safer in a pandemic context.

Hyperinsulinemia and hyperglycemia: risk factors for recurrence of benign paroxysmal positional vertigo

IntroductionChanges in carbohydrate metabolism may lead to recurrence of benign paroxysmal positional vertigo.ObjectiveTo evaluate the influence of the disturbance of carbohydrate metabolism in the recurrence of idiopathic BPPV.MethodsA longitudinal prospective study of a cohort, with 41 months follow-up. We analyzed the results of 72 glucose–insulin curves in patients with recurrence of BPPV. The curves were classified into intolerance, hyperinsulinemia, hyperglycemia and normal.ResultsThe RR for hyperinsulinism was 4.66 and p = 0.0015. Existing hyperglycemia showed an RR = 2.47, with p = 0.0123. Glucose intolerance had a RR of 0.63, with p = 0.096. When the examination was within normal limits, the result was RR = 0.2225 and p = 0.030.DiscussionMetabolic changes can cause dizziness and vertigo and are very common in people who have cochleovestibular disorders. However, few studies discuss the relationship between idiopathic BPPV and alterations in carbohydrate metabolism. In the present study, we found that both hyperglycemia and hyperinsulinemia are risk factors for the recurrence of BPPV, whereas a normal test was considered a protective factor; all these were statistically significant. Glucose intolerance that was already present was not statistically significant in the group evaluated.ConclusionHyperinsulinemia and hyperglycemia are risk factors for the recurrence of idiopathic BPPV and a normal exam is considered a protective factor.
