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.     

Epley's canalith-repositioning manoeuvre for benign paroxysmal positional vertigo

The efficacy of the Epley's canalith-repositioning manoeuvre in the treatment of BPPV was assessed in this prospective study of 62 patients. Patients were selected based on symptoms of positional vertigo and positive Dix-Hallpike's positional test. Patients were divided into two groups; first group comprising 34 patients underwent Epley's manoeuvre alone where as the other group comprising 28 patients underwent Epley's manoeuvre along with mastoid oscillator. At the end of 1 month patients were assessed subjectively by visual analogue scale (VAS) and objectively by Dix-Hallpike's positional test. On VAS, 85.7% patients had complete resolution of symptoms of BPPV in both the groups. Objectively 88.2% did not have positional nysfagmus after 1 month in first group whereas in the second group 86% had complete response at the end of 1 month of therapy. Follow up of 6 months could be done in 38 patients, out of which 7 (18.4%) had recurrence of their symptom of vertigo and positive Dix-Hallpike's positional test, whereas one patient continued to have no relief by Epley's manoeuvre. There was no difference in subjective and objective parameters even when CRP was performed using mastoid vibrator.     

The Epley manoeuvre for benign paroxysmal positional vertigo – a systematic review

Benign paroxysmal positional vertigo (BPPV) is a syndrome characterized by short‐lived episodes of vertigo in association with rapid changes in head position. Current treatment approaches include rehabilitative exercises and physical manoeuvres including the Epley manouevre. Randomized clinical trials of the Epley manoeuvre were identified. Outcome measures that were considered include: frequency and severity of attacks of vertigo; proportion of patients improved by each intervention; and conversion of a ‘positive’ Dix–Hallpike test to a ‘negative’ Dix–Hallpike test. Patients who received the Epley manoeuvre were more likely to have complete resolution of their symptoms [odds ratio 4.92 (95% C.I. 1.84–13.16)], and more likely to convert from a positive to negative Dix–Hallpike test [odds ratio 5.67 (95% C.I. 2.21–14.56)]. There were no serious adverse effects of treatment. There is some evidence that the Epley manouevre is a safe effective treatment for posterior canal BPPV.     

Clinical characteristics and treatment outcomes for benign paroxysmal positional vertigo comorbid with hypertension

Conclusions: Patients with BPPV comorbid with hypertension (h-BPPV) tend to receive a delayed diagnosis of BPPV. Comorbidity with hypertension did not influence the efficacy of the repositioning maneuver; however, comorbidity with hypertension was associated with an increased recurrence rate of BPPV.

Objectives: To determine the clinical characteristics and outcomes of h-BPPV, as well as the clinical differences between h-BPPV and idiopathic BPPV (i-BPPV).

Methods: The authors reviewed the medical records of 41 consecutive patients with h-BPPV (the h-BPPV group) from March to December 2014 and 47 patients with i-BPPV (the i-BPPV group) during the same period.

Results: There were no significant differences in age, sex ratio, or the affected side between the h-BPPV and i-BPPV groups. The proportion of patients reporting an initial episode of positional vertigo was significantly lower in the h-BPPV group (51.22% vs 74.47%; p?=?.024). Patients in the h-BPPV group reported a longer median episode duration than did those in the i-BPPV group (60 days vs 15 days; p?=?.017). The results of treatment using repositioning maneuvers were similar between the two groups. At follow-up, 13 patients in the h-BPPV group were diagnosed with recurrent BPPV compared with six in the i-BPPV group (p?=?.031).

目的探讨良性阵发性位置性眩晕的临床特征。方法回顾160例确诊BPPV患者,分析其临床资料。结果BPPV发病年龄为7-82岁,好发年龄段均为50—70岁,男女比例为0．68：1。发生于后半规管的BPPV为113例（70．6％）,水平半规管为21例（13．1％）,有26例（16．3％）为同时发生于后半规管和外侧半规管。47例水平半规管BPPV中,33例（70．2％）为半规管耳石,14例（29．8％）为壶腹嵴顶耳石。确诊患者中,有98例（61．3％）为首次发作,有49例（30．6％）为复发,或者有明确的类似发作病史。13例（8．1％）曾有眩晕发作,但具体发病特征不明确。对P—BPPV以Epley复位,1周后复查有效率为81．4％（92／113）。半规管型H—BPPV以Lempert法复位,有效率为72．7％（24／33）。壶腹嵴顶型H—BPPV采用强迫体位（健侧卧位）治疗,1周后复查有38．5％（5／13）转为半规管型,以Lempert法复位奏效。随访1月有12例复发（9例P—BPPV和3例H—BPPV）。结论BPPv在各年龄段均有发作,通过患者的发病特征和详细的神经耳科学检查可以做出诊断。根据不同类型进行复位治疗可以取得较好的疗效。     

Benign paroxysmal positional vertigo and post-treatment quality of life

Benign paroxysmal positional vertigo is probably the most common cause of vertigo. It is characterized by acute short-lived episodes of severe vertigo in association with change in the position of the head. This condition is benign, and after the repositioning procedure, the cure rate is between 70 to 80%. Numerous studies describe the association between vertigo and social handicap and emotional disturbance. In our study, we report for the first time the level of anxiety and social consequences, tested with the Hamilton anxiety scale and vertigo handicap questionnaire, in a group of patients who had suffered only from positional vertigo and were clinically cured when the questionnaires and test were administered. The important role played by psychological factors in maintaining or increasing the social consequences and perception of vertigo is revealed in this study.     

Unilateral mimicking bilateral BPPV- a forgotten entity? Characteristics of a large cohort of patients,comparison with posterior canal BPPV and clinical implications

ObjectiveUnilateral mimicking bilateral benign paroxysmal positional vertigo (umb-BPPV) was attributed to inappropriate head positioning during testing of the posterior canal. Despite its inclusion in the Diagnostic criteria for the classification of vestibular disorders of the Bárány Society, the clinical characteristics and treatment responsiveness of this BPPV subtype have not been intensively studied.MethodsRecords of patients with BPPV seen at a single outpatient dizziness clinic during the years 2000–2020 were reviewed. Eighty seven patients with umb-BPPV and 86 random patients with posterior canal BPPV (p-BPPV) were retrieved. Their demographics and BPPV characteristics were analyzed.ResultsPatients' and BPPV characteristics were similar in umb- and p-BPPV except for the prevalence of males in the umb-BPPV group. No differences were found between treatment responsiveness and recurrences in both groups. The recurrence rate of umb-BPPV was not influenced by age, gender, BPPV side, duration of symptoms or treatment responsiveness during the first attack.ConclusionsIn accordance with our hypothesis about mixed canalo- and cupulolithiasis as the underlying mechanism of umb-BPPV, patients did not differ in characteristics and treatment responsiveness from p-BPPV patients. Recognition of umb-BPPV is important since inappropriate treatment can cause an unnecessary delay in therapy success.

Canal switch after canalith repositioning procedure for benign paroxysmal positional vertigo

Canal switch is a complication following canalith repositioning procedure (CRP) for posterior canal benign paroxysmal positional vertigo (BPPV). Instead of being returned to the utricle, the loose otoconia migrate into the superior or horizontal semicircular canal. Patients remain symptomatic, and treatment can be ineffective unless the switch is recognized and additional repositioning maneuvers directed toward the appropriate semicircular canal are performed. This report provides the first videographic documentation of canal switch involving conversion of unilateral posterior semicircular canal BPPV to geotropic horizontal canalithiasis.

The canalith repositioning maneuver in patients with benign positional vertigo

The canalith repositioning maneuver (CRM), as defined by Epley, can be an effective treatment for benign paroxysmal positional vertigo (BPPV). The staff at Başkent University’s Ear Nose and Throat Clinic performed CRM on 68 cases of canalithiasis in 64 BPPV patients from June 1996 to August 1997. Symptoms resolved after the first session in 49 patients (72%) and after the second session in 11 cases (16.2%). It was necessary to repeat the maneuver three times in two cases (2.9%) and four times in one patient (1.5%). Discounting three patients who were lost to follow-up, only two patients in our study did not respond to CRM treatment. There was no co-existing pathology found in all but two of the patients studied. Our experience indicates that unless there is no response to CRM or there is suspicion of an incorrect diagnosis, it is not necessary to perform diagnostic studies routinely for differentiating other neuro-otologic disorders prior to using CRM in BPPV patients diagnosed by the Dix-Hallpike test.

Purely vertical upbeat nystagmus in bilateral posterior canal benign paroxysmal positional vertigo: A case report

Vertical nystagmus occurs in patients with central vestibular system pathology. Lesions of the pons, medulla, and cerebellum lead to vertical nystagmus. Given this association, vertical nystagmus is considered pathognomonic in nature. We present a case of benign paroxysmal positional vertigo (BPPV) with positive Dix‐Hallpike bilaterally, but also with upbeat purely vertical nystagmus in the straight back head hanging position. Computed tomography imaging of the typically pathologic structures in vertical nystagmus (brainstem/posterior fossa) revealed normal anatomy. We propose this case as an instance of peripheral‐associated purely vertical nystagmus without central pathology, while building on our previous understanding of BPPV physiology.

Vibration with the canalith repositioning maneuver: a prospective randomized study to determine efficacy

OBJECTIVES/HYPOTHESIS: The objective was to determine whether the inclusion of vibration and additional treatment cycles has an effect on short- and long-term success rates in the treatment of benign paroxysmal positional vertigo with the canalith repositioning maneuver. STUDY DESIGN: Prospective randomized study of patients treated at a tertiary vestibular rehabilitation center. METHODS: Variables identified for statistical analysis included patient age, gender, vibration used, and canalith repositioning cycles. Analysis using Student t test, chi2 test, Kaplan-Meier curves with log rank test, and Cox proportional hazards regression was performed. RESULTS: One hundred two patients with benign paroxysmal positional vertigo treated over a 1-year period (August 2001-August 2002) were randomly assigned to receive the canalith repositioning maneuver with or without vibration. Average duration of follow-up was 9.44 months. The single treatment success rate was 93.1%. To relieve symptoms, 29.4% of patients required more than one canalith repositioning cycle. The relapse rate was 30.5%. Thirty-nine patients were assigned to the canalith repositioning group with vibration, and 63 to the canalith repositioning group without vibration. There was no statistical difference in age, gender, initial success rates, or relapse rates between the canalith repositioning groups with and without vibration. On average, patients required 1.38 canalith repositioning cycles for successful treatment. Vibration did not affect the number of canalith repositioning cycles required to convert the Dix-Hallpike test result to normal. The need for additional canalith repositioning cycles had no statistical effect on initial treatment success or relapse rates. CONCLUSION: Vibration provided no additional benefit in initial treatment success or in reducing long-term relapse rates when included in the canalith repositioning maneuver. Many patients with benign paroxysmal positional vertigo require more than one canalith repositioning cycle at the time of initial treatment to relieve symptoms, but this does not indicate a higher likelihood for recurrence. No variable predicted a higher rate of recurrence.
