[The clinical value of vestibular autorotation test in the diagnosis of otogenic vertigo].

Objective:To explore the clinical value of vestibular autorotation test (VAT) in the treatment for otogenic vertigo patients. Method:One hundred and twenty-nine definite otogenic vertigo patients were included. All patients underwent the VAT and caloric test (CT). The results were analyzed statistically. Result:In VAT examination, 89 (69.0%) cases were abnormal. In CT examination, 56 (43.4%) cases were abnormal. In the contrast test of VAT and CT, VAT results were abnormal in 47 (36.4%) patients and CT results were abnormal in 14 (10.9%) patients. The number of patients whose both VAT and CT results were abnormal was 42 (32.6%). The total number of patients with various abnormal results was 103 (79.8%). According to statistical analysis, the abnormal result rate of VAT was higher than that of CT. The abnormal result rate of both VAT and CT was higher than that of each single test. There was statistic significance in the difference (χ²=1.670, P<0.05). Conclusion:For otogenic vertigo patients, their abnormal result rate of VAT is higher than that of CT. VAT and CT can be mutually complementary. The combination of VAT and CT can help to understand the function of semicircular canal in the general and provide reference for the treatment of otogenic vertigo diseases.
