Abstract：Objective To report the Dizziness Handicap Inventory(DHI)scores and residual symptoms outcomes after successful reduction in patients with idiopathic benign paroxysmal positional vertigo(BPPV).Methods Data from patients with idiopathic BPPV and successfully treated with reduction(n=117)at the Department of Ootolaryngology of Dongyang People's Hospital from September 2021 to February 2023 were retrospectively reviewed.Cases with residual symptoms(n=88)were divided into two groups based on treatments received,i.e.betahistine only(control group,n=44)or betahistine plus vestibular rehabilitation training(study group,n=44).DHI scores before and after reduction were compared between cases with residual symptoms and those without(n=29).For cases with residual symptoms,duration of residual symptoms,DHI score,and recurrence of BPPV within half a year were compared between the study and control groups.Results The DHI score was reduced in both cases with residual symptoms and those without after reduction therapies,and more so in the latter(P<0.05).In cases with residual symptoms,duration of residual symptoms in the study group was shorter than in the control group(P<0.05).After treatment,DHI score improved in both groups,more so in the study group(P<0.05),with no significant difference in recurrence between them within half a year(P>0.05).Conclusion Patients with idiopathic BPPV may have residual symptoms after successful reduction,which can be effectively improved by betahistine combined with vestibular rehabilitation training.
