前庭功能联合眼震视图检查在原发性良性阵发性位置性眩晕临床诊断中的意义

The significance of vestibular function combined with videonystagmography in the clinical diagnosis of primary benign paroxysmal positional vertigo

目的探究前庭功能联合眼震视图(nystagmus view,VNG)检查在原发性良性阵发性位置性眩晕(BPPV)临床诊断中的意义。方法比较裸眼检查和VNG对BPPV患者的检出率,并采用冷热试验检测BPPV患者前庭功能异常情况。结果VNG和裸眼检查原发性BPPV总检出率分别为91.18%、67.65%,两种检查方法总检出率差异有统计学意义(χ^(2)=17.270,P=0.000)。水平半规管型、后半规管型BPPV患者VNG和裸眼检查检出有明显差异(χ^(2)=4.457、11.942,P<0.05)。不同类型的BPPV患者凝视检测、扫视异常数和平稳跟踪检测结果异常无明显差异(P>0.05);冷热试验显示BPPV异常患者与正常患者分别为66.67%和33.33%。结论前庭功能联合VNG检查对原发性BPPV有一定临床诊断价值。

OBJECTIVE To explore the clinical signif icance of vestibular function combined with videonystagmography in the diagnosis of primary benign paroxysmal positional vertigo.METHODS The detection rate of patients with primary benign paroxysmal positional vertigo(BPPV)was compared between naked eye examination and videonystagmography,and the abnormal vestibular function of patients with BPPV was detected by cold and hot test.RESULTS The total detection rates of primary benign paroxysmal positional vertigo by videonystagmography and naked eye examination were 91.18%and 67.65%,respectively.There was a significant difference between the two methods(χ^(2)=17.270,P=0.000).There was significant difference between the nystagmus view and naked eye examination in the patients with benign paroxysmal positional vertigo of anterior and horizontal semicircular canal types(χ^(2)=4.457,11.942,P<0.05).There was no significant difference in the abnormal number of gaze test,saccade test and stationary tracking test among different types of BPPV patients(P>0.05).Cold and heat tests showed that 68 patients(66.67%)with abnormal BPPV and 34(33.33%)with normal BPPV.CONCLUSION Vestibular function combined with nystagmus has certain clinical value in the diagnosis of primary benign paroxysmal positional vertigo.
