Abstract

Background and Objectives This work investigates the clinical characteristics of benign paroxysmal positional vertigo (BPPV) according to etiology by comparing idiopathic BPPV (iBPPV), BPPV occurring after head trauma (tBPPV) and BPPV associated with idiopathic sudden sensory neural hearing loss (sBPPV). Subjects and Method A total of 869 patients who were diagnosed and treated for BPPV were reviewed retrospectively. Patients were divided into three groups according to the probable etiology of BPPV: iBPPV vs. tBPPV vs. sBPPV. We investigated and compared demographics, the affected sides and canals, the number of canalith repositioning procedure (CRP) performed to achieve successful reposition, canal conversion and recurrence among the three groups. Among the three groups, BPPV patients who performed caloric test and/or video head impulse test (vHIT) were additionally evaluated and compared. Results The iBPPV group (n=787) had greater female preponderance (72%, 567/787) than the tBPPV (n=51) and sBPPV groups (n=31, p<0.001). The mean number of CRPs needed for successful repositioning in the iBPPV group (1.40±0.03) was significantly (p<0.001) lower than that in the tBPPV and sBPPV groups (2.04±0.24 and 2.45±0.36). There was no difference between the tBPPV and sBPPV groups. Recurrence rate was not significantly different among three groups (14.6% vs. 17.7% vs. 16.2%) statistically. The presence of canal paresis and abnormal results of vHIT test were not related with a greater number of CRPs required and recurrence. Conclusion More CRPs were required for successful repositioning in the tBPPV and sBPPV patients than in the iBPPV patients and there was no difference between tBPPV and sBPPV patients. Recurrence rate was not different among the three groups. This information may be helpful for clinicians in counselling and managing BPPV patients.
