Clinical features of benign paroxysmal positional vertigo of the posterior semicircular canal

Abstract

Objective:The aim of this study was to evaluate the relationship between age, gender and affected ear, in patients presenting benign paroxysmal positional vertigo.Methods:This was a retrospective study. Data from benign paroxysmal positional vertigo clinical reports (January 2009–December 2014) were analysed. A total of 174 patients affected by benign paroxysmal positional vertigo of the posterior semicircular canal have been identified. Pearson chi-square test has been used to evaluate the probability of benign paroxysmal positional vertigo occurrence in relation to gender and side, within the studied groups. The level of significance was set at a p < 0.05.Results:Considering age as a discriminant factor, three groups of patients were identified: group 1: 16 patients with an age <40 years; group 2: 79 patients with an age between 40 and 65 years and group 3: 79 patients with an age >65 years. In each group, the right posterior semicircular canal was involved in the majority of cases (group 1 incidence: 12/16; group 2 incidence: 49/79 and group 3 incidence: 52/79). In all three groups, female patients were significantly more affected (9/16 in group 1, 61/79 in group 2 and 55/79 in group 3).Conclusion:Benign paroxysmal positional vertigo is most prevalent in female subjects having an age>40 years and mainly involves the right posterior semicircular canal.

Một Số Đặc Điểm Lâm Sàng, Cận Lâm Sàng Ở Bệnh Nhân Chóng Mặt Tư Thế Kịch Phát Lành Tính

“…Tuổi trung bình ở nhóm bệnh nhân BPPV trong nghiên cứu của chúng tôi là 66,52±12,38 tuổi, trong đó 69,8% bệnh nhân trên 60 tuổi, nữ giới chiếm 78,3%. Độ tuổi này cao hơn so với nghiên cứu của Andrea Ciorbal và CS (2019) khi tìm hiểu đặc điểm lâm sàng ở bệnh nhân BPPV cho thấy tuổi trung bình là 60,03 tuổi, có đến 45% bệnh nhân trên 65 tuổi và nữ giới chiếm 71,8% 3 . Một số tiền sử và bệnh lý kèm theo thường gặp bao gồm: Tăng huyết áp (60,9%), Thừa cân béo phì (47,8%), ĐTĐ (47,8%), RL Lipid máu (60,9%), Rối loạn lo âu-trầm cảm (39,1%).…”

Cerebral Outflow Discrepancies in Recurrent Benign Paroxysmal Positional Vertigo: Focus on Ultrasonographic Examination

“…The prevalence of this condition in the general population stands at 10-64 per 100,000, with an average prevalence of 2.4% and an annual incidence of 1.6%, according to the literature [3]. Females are twice as likely as men to be affected, at an average age of >40 years; furthermore, BPPV mainly involves the right posterior semicircular canal [4].…”

Simultaneous Presentation of Benign Paroxysmal Positional Vertigo and Meniere’s Disease – Case Report

“…Benign paroxysmal positional vertigo (BPPV) is one of the most common clinical entities that can be easily treated, but unfortunately in many cases, it is not recognised by the doctors [1], [2], [3]. The annual incidence of BPPV ranges from 0.06 to 0.6%, and its prevalence increases proportionally with the age of patients [4], [5], [6]. It is rarely found in children and population younger than 35 years, where it is often associated with head injuries [7].…”
