Analysis of Risk Factors for Residual Dizziness Patients with Benign Paroxysmal Positional Vertigo / 听力学及言语疾病杂志

ABSTRACT

Objective To study the incidence and duration of residual dizziness after successful repositioning treatment in patients with benign paroxysmal positional vertigo(BPPV) and the clinical factors associated with the residual dizziness.Methods A total of 202 cases of confirmed BPPV patients,61 males and 141 females with the average age of 54.78± 13.71 years old,were followed up for 2 months after successful particle repositioning.The incidence and duration of residual dizziness were analyzed.The risk factors for residual dizziness were analyzed by logistic regression.Results A total of 202 cases of confirmed BPPV were included in this study,and 113 cases complained of residual dizziness.Over the time,residual dizziness disappeared gradually.The differences of the age,the duration of vertigo before treatment,recurrent,and underlying diseases between the two group were significant (P ＜0.05),while the side,the gender,the incubation period of BPPV,the duration time of BPPV,and the types of canals were not associated with the residual dizziness(P＞0.05).The logistic regression analysis showed that the duration of vertigo before treatment and the age were the risk factors for residual dizziness.Conclusion More than half of the patients included in this study complained of residual dizziness after particle repositioning,and the symptoms disappeared naturally.The duration of vertigo before treatment and the age were the risk factors for residual dizziness.
