ABSTRACT
OBJECTIVE:
The purpose of this study was to identify the clinical characteristics of horizontal canal benign paroxysmal positional vertigo (h-BPPV) with persistent geotropic direction changing positional nystagmus (DCPN).METHODS:
One hundred thirty two patients diagnosed as the geotropic subtype of h-BPPV were analyzed retrospectively. Patients were classified into two groups persistent h-BPPV (ph-BPPV) group which means h-BPPV showing persistent (>1 minute) geotropic DCPN and short duration h-BPPV (sh-BPPV) group that means h-BPPV with short duration (< or =1 minute) geotropic DCPN. We compared the clinical characteristics and treatment outcomes between the two groups.RESULTS:
The study included 34 patients with ph-BPPV and 98 patients with sh-BPPV. There were no differences between the two groups in age, distribution of sex and the affected side. The ph-BPPV group had higher secondary BPPV preponderance and dizziness handicap index (DHI) score compared to the sh-BPPV group. The ph-BPPV group required higher number of canalith repositioning procedures (CRPs) until resolution and higher multiple/single CRP ratio than the sh-BPPV group. In addition, the ph-BPPV group showed longer duration until the remission of subjective symptoms (vertigo, dizziness) compared to the sh-BPPV group.CONCLUSION:
ph-BPPV was more frequently associated with secondary causes of BPPV and demonstrated higher DHI score, total number of CRP, and longer remission duration of subjective symptoms compared to sh-BPPV. This information may be helpful for clinicians in counseling and managing the patients with persistent geotropic DCPN h-BPPV.Palavras-chave
