良性阵发性位置性眩晕患者温度试验结果比较

目的比较后半规管良性阵发性位置性眩晕 （posterior semicircular canal benign paroxysmal positional vertigo, PSC-BPPV）和外半规管BPPV（horizontalsemicircularcanalBPPV，HSC-BPPV）温度实验结果的差异。方法2006～2008年门诊原发性BPPV患者177例，其中单侧PSC—BPPV患者152例，单侧HSC-BPPV患者25例，Dix-Hallpike及翻转试验检查后做温度实验检查，分析半规管轻瘫（canalparesis，CP）和优势偏向（directi0138Ipreponderance，DP）。结果①CP结果：PSC—BPPV患侧CP64例（42．1％），健侧CP44例（28。9％），两者差异有显著性（X2=5．74，P〈0．05）；HSC-BPPV患侧CP16例（64％），健侧CP9例（36％），两者差异有显著性（X2=3．92，P〈0．05）；PSC-BPPV患者实际病变侧别与温度试验显示的CP侧别一致的有46例（30．3％），HSC．BPPV患者实际病变侧别与温度试验显示的CP侧别一致的有13例（52％），两者差异有显著性（X2=4．56，P〈0．05）：②DP结果：PSC-BPPV患者DP13例，HSC．BPPV患者DP1O例，经统计学分析有显著性差异（X2=16．10，P〈0．01）。结论①HSC—BPPV及PSC．BPPV患者温度试验患侧CP发生率明显高于健侧；②HSC-BPPV患者温度试验CP发生率明显高于PSC．BPPV患者；⑨HSC．BPPV患者温度试验DP发生率明显高于PSC—BPPV患者。

Comparison of caloric test findings in benign paroxysmal positional vertigo

OBJECTIVE To analyze the caloric test findings of the unilateral primary horizontal and posterior semicircular canal benign paroxysmal positional vertigo(HSC-BPPV and PSC-BPPV).METHODS Caloric test were tested in 152 PSC-BPPV patients and 25 HSC-BPPV patients after Dix-Hallpike test and Roll test.RESULTS Of 152 PSC-BPPV patients 64 canal paresis(CP)were found in the abnormal side and 44 in the normal side;Of 25 HSC-BPPV patients 16 canal paresis were found in the abnormal side and 9 in the normal side.The i...
