Abstract

Objective:To explore risk factors in the onset of benign paroxysmal positional vertigo(BPPV) by questionnaires and laboratory tests. Method:Three hundred and ten cases of patients with BPPV were conducted. All patients' informations were collected, including age, smoking history, with or without high blood pressure, diabetes, cervical spondylosis, tinnitus, and vertigo. Laboratory tests including pure tone hearing level, electrical diagram of nystagmus,CT, TCD, cervical vertebra X-ray were performed, and data were analyzed. Result:All 310 patients were a total of 215 females (69.4%) and 95 males(30.6%), aged from 20 to 84 years, with a median age of 54. There were 217 cases(70.0%) of PC-BPPV,88 cases(28.4%) of HC-BPPV, and 2 cases(0.6%)of AC-BPPV. Among patients, 106 patients(34.2%) had high blood pressure, 36 patients(11.6%) had diabetes, 123 patients(39.7%) had cervical disease, 91 cases were found cerebral infarction in CT, 152 patients(49.0%) had tinnitus, and 59 patients(19.0%) had history of smoking. Conclusion:Incidence of BPPV is related with gender and ages. Incidences of high blood pressure and brain ischemic change in BPPV patients were higher than that in the general population.
