Abstract
Objective:To investigate the clinical features of the recurrence of idiopathic benign paroxysmal positional vertigo(IBPPV)patients.Method:Patients with IBPPV were enrolled and were followed-up for 36 months after being well controlled.The data of the patients including age,gender,and co-morbidities(hypertension,diabetes,hyperlipidemia)were analyzed.Characteristics of the patients with recurrent BPPV were compared with those without recurrence.Result:Two hundred and one patients were enrolled and twenty-two(10.9%)patients presented recurrent IBPPV within 36 months.Among them,about 16% showed changes in the involved semicircular canals.50% recurrence occurred within 6 months after the first treatment.The recurrence rate of BPPV in 50-60 years old patients(50%)is higher than other patients(P=0.04).No significant difference in terms of gender or co-morbidities(hypertension,diabetes,hyperlipidemia)was observed between the two groups.Conclusion:The incidence of recurrence in idiopathic BPPV patients was 10.9%in the present study.The mean period of 50% recurrence after a symptom-free interval was about 6 months.Furthermore,different semicircular canals were involved in about 50% of patients during recurrence.BPPV recurrence was not correlated with age,gender or co-morbiditie.
