摘　　要：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(horizontal semicircular canal BPPV,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(canal paresis,CP)和优势偏向(directional preponderance,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(χ2=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(χ2=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(χ2=4.56,P<0.05);②DP结果:PSC-BPPV患者DP13例,HSC-BPPV患者DP10例,经统计学分析有显著性差异(χ2=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;③HSC-BPPV患者温度试验DP发生率明显高于PSC-BPPV患者。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 incidence of CP in PSC-BPPV is 30.3% and the incidence of CP in HSC-BPPV is 52%. 13 Patients with PSC-BPPV were found abnormal Directional Preponderance （DP） and 10 Patients with PSC-BPPV were found abnormal Directional Preponderance. CONCLUSION The incidence of CP in the abnormal side of HSC- BPPV and PSC-BPPV is more than that of the normal side. The incidence of CP in abnormal side of the HSC- BPPV is more than that of PSC-BPPV. The incidence of abnormal DP in HSC-BPPV is more than that of PSC-BPPV.
