Analysis of clinical characteristics and risk factors in patients with benign paroxysmal positional vertigo

2021 
〓 Objective: To analyze the clinical characteristics of patients with benign paroxysmal positional vertigo, summarize experience for diagnosis and treatment activities and to explore the risk factors related to the onset of BPPV and provide reference for early intervention to reduce the risk factor exposure of BPPV. Methods:One hundred and twelve patients with BPPV were included in the study, and clinical data including age, gender, onset symptoms and duration, past medical history and family history were analyzed. A One-way ANOVA was performed on 16 variables using age, gender, diabetes, hyperuric acid, hyperlipidemia, osteoporosis, hypertension, coronary heart disease, stroke, Meniere's disease, suppurative otitis media, vestibular neuronitis, sudden deafness, head injury, ear nose/maxillofacial surgery and autoimmune thyroiditis. The statistically significant parameters of the one-way ANOVA were included in the multivariate regression analysis to explore the independent risk factors for BPPV. Results:Seventy-six cases(67.86%) of BPPV patients were primary BPPV, 36 cases(32.14%) were secondary BPPV(P<0.01). The gender composition(male, female), ears involvement(unilateral, bilateral) and semicircular canal involvement(posterior semicircular canal, horizontal semicircular canal, anterior semicircular canal, mixed type) were different between the two groups(P<0.05). During the follow-up period, 34(30.36%) patients relapsed, of which 19(25.00%) were the primary patients and 15(41.67%) were the secondary patients(P<0.01). Diabetes(P=0.004), osteoporosis(P=0.017), hypertension(P=0.013), stroke(P=0.005) and suppurative otitis media(P=0.031) were related to the onset of BPPV. Conclusion:BPPV patients are mainly primary, while the secondary patients are more likely to relapse after being cured. Diabetes, osteoporosis, hypertension, stroke and suppurative otitis media are independent risk factors for the onset of BPPV.
