目的:探讨特发性良性阵发性位置性眩晕(BPPV)患者双温试验以及双温试验异常的可能机制。方法:2005-2008年诊断明确的96例特发性BPPV患者,随机分为2组:第1组52例,在诊断明确后复位治疗前进行双温试验;第2组44例,在复位治疗后变位试验阴性后进行双温试验。以半规管轻瘫指数作为比较参数,χ2检验比较2组半规管轻瘫异常的比例。结果:2组患者比较,除第1组年龄较第2组低,性别比例、受累半规管比例、侧别、病程、是否反复发作各个因素之间没有明显差别。双温试验的比较以半规管轻瘫作为比较参数,2组患者温度试验半规管轻瘫异常的比例进行χ2检验(t=0.654,P<0.05),2组半规管轻瘫出现的比例相似,管石复位前后温度试验异常出现的比例差别没有统计学意义。结论:双温试验异常的原因可能是因为前庭系统存在广泛病变,飘动的耳石对内淋巴液的流动影响不大。
Objective: To investigate the dual-temperature test and the possible mechanism of abnormalities of dual-temperature test in patients with idiopathic benign paroxysmal positional vertigo (BPPV). Methods: A total of 96 patients with idiopathic BPPV diagnosed from 2005 to 2008 were randomly divided into 2 groups: group 1 (52 cases), double-temperature test before diagnosis and reoperation; group 2 (44 cases) After the negative displacement test after the double temperature test. Semi-regulatory paresis index as a comparative parameter, χ2 test compared two groups of semicircular canal paralysis abnormal proportions. Results: There was no significant difference between the two groups except for the lower age group 1, the sex ratio, the ratio of semicircular canal involvement, side, course of disease and recurrent episodes. Comparison of the two-temperature test for semicircular canal paresis as a comparative parameter, two groups of patients with semicircular canal temperature patellar paralysis abnormalities ratio χ2 test (t = 0.654, P <0.05), two groups of semicircular canal paralysis appeared similar proportions, There was no significant difference in the proportion of anomalous temperature test before and after. CONCLUSION: The reason for the abnormality of the dual-temperature test may be that the vestibular system has extensive lesions and the fluttering otolith has little effect on the flow of the endolymph.
