To analyze the clinical features of Vestibular migraine（VM） and provide evidence for its accurate diagnosis and medical identification of flight personnel. A total of 490 samples of VM patients were collected. Among them, 88 samples were secondary to benign paroxysmal positional vertigo（BPPV）, and 11 samples were co-occurring with Meniere’s disease（MD）. All patients received drugs, lifestyle management, vestibular rehabilitation and other comprehensive treatment, and analyzed the clinical features and effect within 6 months. ①The male-female ratio of VM patients was 1∶1.95, the average age was （50.2±14.3） years old, （48.7±15.0） years old for males and （51.0±13.9） years old for females. No statistically significant differences were found（>0.05）. The average duration was（54.5±84.8） months, （35.0±59.0） months for males and（64.7±94.0） months for females. The difference was statistically significant（<0.05）. ②The main clinical symptoms are dizziness, migraine or previous history of migraine, fear of sound/noisy environment sensitivity, photophobia/visual sensitivity, nausea/vomiting, vestibular posture symptoms, tinnitus, hearing loss, etc. , diarrhea during dizziness or headache was one special symptom of VM; ③The abnormal rate of vestibular autorotation test（VAT） in 118 VM patients was 72.3%, while the abnormal rate of caloric test in 170 VM patients was 32.9%; ④The effective remission rate within 6 months of VM patients with secondary BPPV and MD was 78.6% and 83.4%, while the VM patients without secondary benign paroxysmal positional vertigo（BPPV） and Meniere's disease（MD） was 93.3%. The difference was statistically significant（<0.05）. The clinical manifestations of VM patients were various. Female VM patients had higher incidence, the course of disease than male VM patients, diarrhea can be regarded as one of the clinical features distinguished from MD. The abnormal rate of VAT was higher in the common clinical examiniations of VM patients. VM patients treatment should focus on personalized prescription and lifestyle management, vestibular rehabilitation, and corresponding treatment at the same time should be given to patients with secondary BPPV and MD to improve the efficacy. The medical identification of flight personnel VM patients should be strictly controlled, pilots should be grounded, while flight combat personnel and flight technical personnel need chartered medical identification.Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.
