摘要
目的通过实验室检查来评估良性复发性眩晕患者的前庭功能,了解其前庭功能特点。方法对32例良性复发性眩晕患者完善冷热(水)试验(caloric test)、速度阶梯试验(Velocity step test)、摇头试验(head-shaking nystag-mus,HNS)及颈肌性前庭诱发肌源电位检查(cervical Vestibular-Evoked Myogenic Potentials,c VEMP),同时对30例健康志愿者完善以上前庭功能检查,对试验组和对照组的上述检查结果进行分析。结果 32例良性复发性眩晕患者中,22例(68.75%)患者至少在一个水平半规管功能试验中出现异常,异常率最高的是冷热(水)试验,其次是速度阶梯试验和摇头试验。试验组水平半规管功能的异常率明显高于正常对照组,差异有显著统计学意义(P<0.05)。试验组患者的颈肌性前庭诱发肌源电位异常率(21.9%)明显高于对照组(3.3%),差异有显著统计学意义(P<0.05)。结论对良性复发性眩晕患者,冷热试验、摇头试验、速度阶梯试验及c VEMP检查具有一定的临床意义,全面评估患者的前庭功能情况,具有一定的临床参考价值。
Objective The purpose of this study was to investigate the vestibular function in patients with Benign recurrent vertigo by laboratory tests, to explore its vestibular features.Methods Thirty-two patients with Benign recurrent vertigo and Thirty healthy volunteers were completed caloric test,HNS,rotational test and cVEMP.Analyze the abnormal results of caloric test,HNS and, rotational test and cVEMP between two groups. Results Among 32 patients with benign re- current vertigo, 22 （68.75%） patients showed abnormal function of horizontal semicircular canal indicated at least by one of the tests, with the highest abnormal rate in the cold （water） test, followed by the speed ladder test and head-shaking test. Abnormal rate of horizontal semicircular canal function in the experimental group was significantly higher than that in control group（P 〈0.05）. abnormal rate （21.9%） of cVEMP in the experimental group was higher than that （3.3%） in control group（P 〈0.05）. Conclusion Vestibular function tests, including the caloric test, head-shaking test, speed ladder test and cVEMP, are important to assess the vestibular function of the patient with benign recurrent vertigo.
