【摘要】：目的 本文拟通过对112例特发性BPPV患者冷热试验结果的分析,以期发现BPPV在前庭功能检查方面的一些特点,进一步了解BPPV的可能发病机制。 方法 以2006年一2010年我科门诊就诊的眩晕患者中112例诊断为特发性BPPV者,其中后半规管性BPPV(PC-BPPV)91例,外半规管BPPV(HC-BPPV)19例,前半规管BPPV(AC-BPPV)2例,进行双耳交替冷热试验(Calorictest,CT)检测。以半规管轻瘫值(CP)为评定参数,分析PC-BPPV和HC-BPPV这两种BPPV类型在温度试验检查中的差异,探讨差异的可能原因及机制。 结果 91例PC-BPPV,患侧CP 26例,健侧CP 14例,患侧CP发生率高于键侧,两者差异有统计学意义;19例HC-BPPV,患侧CP 10例,健侧CP 1例,患侧CP发生率高于健侧,两者存在显著差异,有统计学意义;PC-BPPV中患侧CP 26例,HC-BPPV中患侧CP 10例,HC-BPPV患侧CP发生率高于PC-BPPV患侧CP发生率,两者差异有统计学意义。 结论 特发性PC-BPPV和HC-BPPV患者温度试验中患侧CP异常发生率明显高于健侧;HC-BPPV患者患侧CP异常发生率明显高于PC-BPPV患者。半规管内飘动的耳石使内淋巴液密度改变对内淋巴产生重力加载可能是使温度试验产生异常的原因之一。除了飘动的耳石,前庭外周系统可能存在广泛的病变。温度试验、摇头试验及前庭自旋转试验联合应用有助于更全面评价BPPV患者的前庭功能。
[Abstract]:Objective to analyze the results of cold and hot tests in 112 patients with idiopathic BPPV in order to find out some characteristics of BPPV in vestibular function examination and to further understand the possible pathogenesis of BPPV. Methods from 2006 to 2010, 112 patients with idiopathic BPPV were diagnosed as idiopathic BPPV, including 91 cases of posterior semicircular canal BPPV (PC-BPPV), 19 cases of outer semicircular canal BPPV (HC-BPPV) and 2 cases of anterior semicircular canal BPPV (AC-BPPV). Using semicircular canal paresis value (CP) as the evaluation parameter, the differences between PC-BPPV and HC-BPPV in temperature test were analyzed, and the possible causes and mechanism of the differences were discussed. Results there were 91 cases of PC-BPPVs, 26 cases of affected side CP, 14 cases of healthy side CP. The incidence of CP in the affected side was higher than that in the key side. The difference between the two cases was statistically significant (P < 0.01). The incidence of CP in the affected side was higher than that in the healthy side, including 10 cases in the affected side and 1 case in the healthy side. There was a significant difference between the two groups. The incidence of CP in the affected side of 26 patients with HC-BPPV was significantly higher than that in the affected side of PC-BPPV, and the difference was statistically significant. Conclusion the incidence of CP abnormality in patients with idiopathic PC-BPPV and HC-BPPV is significantly higher than that in patients with HC-BPPV. The incidence of abnormal CP in patients with HC-BPPV is significantly higher than that in patients with PC-BPPV. The change in the density of endolymphatic fluid caused by the fluttering otoliths in the semicircular canal may be one of the reasons for the abnormal temperature test. In addition to fluttering otoliths, the vestibular peripheral system may have extensive lesions. Combined use of temperature test, shaking test and vestibular self-rotation test is helpful for more comprehensive evaluation of vestibular function in patients with BPPV.
