背景:判断前庭功能的方法有冷热试验及旋转试验,两种方法检测结果相关性如何?目的:观察旋转试验与冷热水试验检查前庭功能结果的一致性。设计:以患者为观察对象,评估方法学优异性的对比实验。单位:解放军总医院耳鼻咽喉科。对象:选择1990-04/1996-12在解放军总医院耳鼻咽喉科因眩晕、耳聋耳鸣就诊的门诊及病房患者为观察对象,所有患者均经用Hallpike冷热水试验检查结果均显示前庭功能异常,且知情同意。其中男68例,女32例;年龄16～74岁,平均(37±3)岁。单侧异常91例,双侧异常9例。前庭功能异常判定标准为[建侧眼震慢相角速度(slowphaseveloci-ty,SPV)-患侧SPV/健侧SPV-患侧SPVX100%]≥15%,上述比值<15%判定为正常。方法:对患者进行旋转试验,分别采用正弦摆动和旋转骤停两种刺激方式,其中正弦摆动试验刺激幅度为90°,频率为0.167Hz;骤停旋转试验,1°～2°/s2加速度达峰速90°/s,恒速旋转至眼震消失后骤停进行测试。主要观察指标:骤停旋转试验及正弦摆动试验结果。结果:按实际处理分析。双侧异常者9例,8例诱发出眼震,1例双侧听神经瘤旋转试验未诱发出眼震。其他患者旋转试验均诱发出眼震。冷热水试验单侧异常的91例患者中有2例由于不愿接受骤停旋转试验而未做。正弦摆动试验检查64%(58/91)患者前庭功能异常,骤停旋转试验检查61%(54/91)患者前庭功能异常。结论:旋转试验中的正弦摆动试验和骤停旋转试验可检查出前庭功能异常,但与冷热水试验结果不完全相符。
Background: There are hot and cold test and rotation test to judge the vestibular function. What is the correlation between the two methods? OBJECTIVE: To observe the consistency of the vestibular function test between rotation test and hot and cold water test. Design: A comparative experiment that evaluates methodological excellence with the patient as the observer. Unit: People’s Liberation Army General Hospital of Otorhinolaryngology. PARTICIPANTS: In the outpatient and ward patients with otolaryngology at the otolaryngology department of PLA General Hospital from 1990-04 / 1996-12, all the patients were examined by Hallpike cold and hot water test. The results showed that the vestibular dysfunction, Informed consent. There were 68 males and 32 females, aged from 16 to 74 years, with an average of (37 ± 3) years. 91 cases of unilateral abnormalities, bilateral abnormalities in 9 cases. The criterion for abnormal vestibular function was judged as [normal phase (SPV) - SPV of contralateral SPV / contralateral SPV-side SPVX100%] ≥15%, and the above ratio <15% was judged as normal. Methods: Rotation test was performed in patients with sinusoidal and rotational arrest respectively. Stimulus amplitude of sinusoidal oscillation test was 90 ° and frequency was 0.167Hz. The arresting rotation test, acceleration of 1 ° ~ 2 ° / s2 Peak speed of 90 ° / s, constant speed rotation to nystagmus disappear after the test was stopped. MAIN OUTCOME MEASURES: STOP ROTATION TEST AND SINEWAVELET TEST RESULTS. Results: According to the actual treatment analysis. 9 cases of bilateral abnormalities, 8 cases of induced nystagmus, 1 case of bilateral acoustic neuroma rotation test did not induce nystagmus. Other patients spin test induced nystagmus. Two of the 91 patients with unilateral hot and cold water tests were unwilling to undergo a spin-off test. Sinus sway test in 64% (58/91) of patients with vestibular dysfunction, arrest rotation test to check 61% (54/91) patients with vestibular dysfunction. CONCLUSIONS: Sinusoidal rotation tests and spin-and-spin tests can detect abnormalities of vestibular function in rotation tests, but not completely in accordance with the results of hot and cold water tests.
