[Classification of acute vestibular syndrome].

Objective: To explore the epidemiological characteristics and to help accomplish accurate diagnosis and treatment strategies by analyzing the composition and clinical features of various diseases with acute constant vertigo. Method: We retrospectively analyzed medical records (including name, sex, age, diabetes, hypertension, history of vertigo, family history, etc.),otoneurological examination, vestibular function tests and radiological examination of patients with acute vestibular syndrome.We classified various diseases according to diagnostic criteria, and then analyze the clinical data. Result: A total of 77 patients with acute vestibular syndrome were enrolled in this study. It included 34 patients with vestibular neuritis, 18 patients with sudden sensorineural deafness with vertigo, 1 with vestibular schwannoma, 6 with acute vestibular syndrome with migraine, 3 with Hunter syndrome with vertigo, 1 with vertigo after trauma,1 with acute bilateral vestibulopathy, 9 with acute vertigo syndrome with other etiology, 3 with acute labyrinthitis, and 1 with posterior circulation infarction. There were no significant differences in the age and course of disease between different etiologies ( P >0.05). There were statistical differences between vestibular neuritis and sudden sensorineural deafness with vertigo among head impulse test and hearing loss ( P <0.05). There was significant difference in hearing between sudden sensorineural deafness with vertigo and acute vertigo syndrome ( P <0.05). Conclusion: Most of the acute vestibular syndrome patients attending the otorhinolaryngology head and neck surgery clinic were peripheral acute vestibular syndrome, vestibular neuritis, and sudden sensorineural deafness with vertigo.Patients with acute vestibular syndrome with migraine are not rare, and central vertigo can also be seen.
