不同听力检测方法甘油试验的结果比较

The Different Audiological Methods to Assess the Results of the Glycerol Test

目的比较纯音测听甘油试验、耳蜗电图甘油试验、畸变产物耳声发射(DPOAE)甘油试验对梅尼埃病的诊断价值。方法选择63例梅尼埃病和63例非梅尼埃病眩晕患者,分为A、B、C三组,每组包括21例梅尼埃病患者和21例非梅尼埃病眩晕患者,在服用甘油前和服用甘油后1、2、3h分别观察三组患者纯音测听(A组)、耳蜗电图(B组)和DPOAE(C组)的变化,比较三组间甘油试验阳性率。结果 A组梅尼埃病患者纯音测听甘油试验阳性率最高为38.10%(18/21),B组耳蜗电图甘油试验阳性率最高为52.38%(11/21),C组DPOAE甘油试验阳性率最高为57.14%(12/21)。结论耳蜗电图和DPOAE的甘油试验较纯音测听的甘油试验更为准确,能在一定程度上提高对梅尼埃病的诊断率。

Objective To investigate the diagnostic application of pure tone audiometry test,EcochG glycerine test and distortion product otoacoustic emission（DPOAE） glycerine test in patients with Mfiniere＇s disease（MD）. Methods A total of 126 patients were included in this study. 63 patients had MD and the remaining 63 patients with vertigo diseases. The patients were divided into 3 groups （group A,B,C）. Each patient underwent glycerol test,and patients in group A,B, C were tested with conventional pure tone audiomety, ECochG and DPOAE, respectively, be- fore and 1,2,3 b, ours after oral administration of glycerol. Results The positive rates of glycerol test in MD were significantly higher than that in other vertigo diseases. The positive incidence of pure tone audiometry glycerol test, ECoehG glycerol test and DPOAE glycerol test in MD patients were 38.1 %, 52.4%and 57.1 %, respectively. All were dected within 2 hours after glycerol test. Conclusion The study shows that the glycerol test has diagnostic value for MD. Futhermore,ECochG glycerol test and DPOAE glycerol test are more accurate for the diagnosis of MD compared with pure tone audiometry glycerol test. We can add ECochG or/and DPOAE during the glycerol test to improve the diagnosis rate of MD.
