Benign paroxysmal positional vertigo (BPPV) is a potentially recurrent disease even after successful canalith repositioning maneuvers. However, the exact recurrence rate or any clinical factors affecting the recurrence of BPPV still need to be elucidated.
Methods
We recruited patients diagnosed as BPPV in a tertiary hospital for 3 years. We retrospectively reviewed the clinical information of the patients including baseline demographics, comorbidities and predisposing factors through the electronic medical records. We performed a telephone survey or direct interview 3 to 6 years later from the initial diagnosis of BPPV was made. To determine the factors associated with the recurrence, we divided study population into two subgroups; ‘recurrence group’ vs. ‘recurrence-free group.’ Then, intergroup comparative analyses were performed.
Results
Among 397 patients who were originally eligible for the study, we performed a telephone survey or direct interview in 289 patients (72.8%) to determine the recurrence of BPPV. The overall recurrence rate was 29.4% (85 of 289). Baseline demographics except female gender (p=0.014) were not different between subgroups. Neither clinical characteristics nor vascular comorbidities were associated with the recurrence. However, patients with low bone mineral density (BMD; T-score below ‒1, osteopenia/osteoporosis) showed significantly higher recurrence than those with normal BMD (40.6% vs. 0%, p=0.009).
Conclusions
Female gender and low BMD (T-score below ‒1) were associated with the recurrence of BPPV in this study. Further researches in various clinical settings with larger sample size are warranted to identify the factors affecting the relapse of BPPV.

Abstract
PDFSupplementary Material
- Relapsing polychondritis is a rare multisystemic autoimmune disorder of unknown etiology and characterized by recurrent episodes of inflammation affecting the cartilaginous tissues. Otologic manifestation such as auricular chondritis is one of the most frequent presenting symptoms in relapsing polychondritis, and inner ear symptoms, such as hearing loss, tinnitus, and vertigo, may develop in 7% to 42% of the patients. In this study, we present a 42-year-old male patient with relapsing polychondritis, who experienced two separate episodes of acute vestibular syndrome at the interval of 6 years. At the first vertigo attack, the patient showed left-beating spontaneous nystagmus with sudden hearing loss on the right side, and a bithermal caloric test revealed canal paresis on the right side. At the second vertigo attack, he showed right-beating spontaneous nystagmus, and a bithermal caloric test, compared to that during the first vertigo attack, revealed additional decrease in caloric response on the left side.

Abstract

- Objective: The purpose of this study was to identify the influence of sleep position on benign paroxysmal positional vertigo (BPPV).
Methods
Four hundred sixty patients diagnosed as posterior or horizontal canal BPPV were analyzed retrospectively. All patients were asked about their preferred sleep positions among the following four choices: supine, right or left lateral, or no predominant side via questionnaire at initial visit and after 1month. Patients were classified into two groups: affected side group meaning that the patient preferred to sleep ipsilateral to the affected ear and other position group including all positions other than lying lateral to the affected side after treatment. We analyzed the change in the sleep pattern after treatment and compared the recurrence rate between the two groups.
Results
Our study included 244 patients with posterior canal BPPV (PC-BPPV) and 216 patients with horizontal canal BPPV (HC-BPPV). Statistically significant correlation was demonstrated between sleep position side and the affected side by BPPV. The number of patients who slept on the affected side by BPPV decreased, while the number of patients who slept on the healthy side increased significantly after treatment. There was no statistically significant difference in the recurrence rate between the two groups.
Conclusion
There was significant correlation between the sleep position side and the affected side in PC-BPPV and HC-BPPV. The patient had a tendency to avoid lying lateral to the affected side by BPPV during sleep after treatment, however the change in sleep position did not influence the recurrence rate of BPPV.

Abstract

- Benign paroxysmal positioning vertigo (BPPV) is the most common disease that causes dizziness which is usually resolved spontaneously or by office-based physical therapy.
However, clinicians sometimes encounter atypical or intractable BPPV cases which show poor effect with physical therapy including canalith reposition therapy and liberative maneuvers and frequent recurrence. There is no common definition, diagnosis and treatment protocols for intractable BPPV. Various types of intractable BPPV and reported treatment methods are discussed in this review.
