[Etiological analysis on patients in department of vertigo and dizziness oriented outpatient].

ABSTRACT

Objective: We aimed to explore the spectrum of causes for patients in department of vertigo and dizziness oriented outpatient, in order to provide a reference for diagnosis and treatment of patients with vertigo or dizziness. Methods: Retrospective analysis were carried out with clinical data of patients in our department of vertigo and dizziness oriented outpatient. The target group under study was diagnosed based on the uniform diagnostic criteria, and re-visiting patients were excluded. Results: This clinical study was conducted on 5 348 cases, who visited our vertigo and dizziness oriented outpatient from December 2012 to July 2015. The ratio of male to female was 1∶1.48, the age range was between 16 and 93. The frequencies of different etiology were benign paroxysmal positional vertigo 1 902(35.56%), Chronic subjective dizziness 1 329(24.85%), vestibular migraine 624(11.67%), Meniere's disease 378(7.07%), multi-sensory neuropathy 231(4.32%), vestibular paroxysmia 177(3.31%), benign recurrent vestibulopathy 171(3.20%), presyncope 66(1.23%), posterior circulation ischemia 57(1.07%), vestibular neuritis 54(1.01%), sudden deafness complicated vertigo 36(0.67%), other reasons 68(1.27%), unknown 255(4.77%). Conclusions: Our study indicates that the precedent three causes for vertigo or dizziness are benign paroxysmal positional vertigo, chronic subjective dizziness and vestibular migraine, followed by Meniere's disease、multi-sensory neuropathy, vestibular paroxysmia and benign recurrent vestibulopathy. Presyncope, posterior circulation ischemia, vestibular neuritis and sudden deafness complicated vertigo are relatively infrequent. There are still a certain proportion of patients undetermined.
