ABSTRACT
BACKGROUND AND OBJECTIVES:
The purpose of this study was to identify the clinical characteristics of benign paroxysmal positional vertigo (BPPV) occurring after head trauma by comparing them to those of idiopathic BPPV (i-BPPV). SUBJECTS ANDMETHOD:
We analyzed retrospectively 820 patients diagnosed with BPPV. Patients were classified into two groups post-traumatic BPPV (t-BPPV) group and i-BPPV group. We compared the clinical characteristics (age, sex, affected side, duration of vertigo, types of BPPV) and treatment outcomes between the two groups.RESULTS:
The study included 497 patients with i-BPPV and 56 patients with t-BPPV. There were no differences in age distribution and the affected side. The t-BPPV group had greater male preponderance (48%) than the i-BPPV group (24%) did and longer duration of vertigo compared to i-BPPV group (p=0.028). In addition, the t-BPPV group demonstrated higher horizontal canal BPPV/posterior canal BPPV ratio (t-BPPV vs. i-BPPV=0.54 vs. 0.20, p=0.008). Although the results of a single treatment outcome did not differ between the two groups (p=0.127), there was a greater tendency for the t-BPPV group to receive a higher number of therapeutic maneuvers until resolution than for the i-BPPV group (p=0.056). Recurrence rate also did not differ between the two groups (p=0.125).CONCLUSION:
The clinical features did not differ significantly between the two groups, although t-BPPV demonstrated a tendency of low therapeutic efficacy and high recurrence rates compared to i-BPPV. This information may be helpful for clinicians in counseling and managing patients with t-BPPV.
