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

摘要: 目的:探讨前庭自旋转试验(VAT)在耳源性眩晕疾病患者中的应用价值。方法:对确诊的129例耳源性眩晕患者进行VAT及冷热试验检查,将结果进行对比分析。结果:VAT检查结果异常者89例(69.0%),冷热试验检查结果异常者56例(43.4%)。两项对比试验中,单独结果异常VAT为47例(36.4%),冷热试验为14例(10.9%);两者均异常42例(32.6%),两者总异常103例(79.8%)。经统计学分析VAT异常的检出率高于冷热试验,总异常的检出率高于任何单一试验异常的检出率,差异有统计学意义(χ2=1.670,P<0.05)。结论:耳源性眩晕患者中VAT异常的检出率高于冷热试验。VAT与冷热试验联合应用,可相互补充,有助于全面了解半规管功能,为耳源性眩晕疾病的诊断提供参考。Abstract: 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 analized 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.
