Abstract:

【】 目的 了解原发性良性阵发性位置性眩晕(benignparoxysmalpositionalvertigo,BPPV)的双温试验及纯音测听结果临床特点。 方法 2009年6月―2010年6月诊断为原发性BPPV患者54例,于手法复位前行双温试验及纯音听阈测试,分析原发性BPPV患者的双温试验、纯音测听结果的临床特点。 结果 40例患耳无半规管轻瘫,其病程为(4.25±2.75)周,14例患耳半规管轻瘫,其病程为(9.21±5.85)周,两组间平均病程差异具有统计学意义(t=4.235,P0.05);39例后半规管BPPV中16例患耳听力下降,15例水平半规管BPPV中7例患耳听力下降,两组患耳纯音测听异常率无明显统计学差异(χ2=0.141,P>0.05)。 结论 原发性后半规管BPPV与水平半规管BPPV半规管轻瘫及纯音听阈异常发生率相近,病程长者更易出现半规管轻瘫。【Abstract】 Objective Toinvestigatetheclinicalfeaturesofresultsofbithermaltestandpuretonetestforpatientswithidiopathicbenignparoxysmalpositionalvertigo(BPPV),anddiscussstrategiesforprevention.
