The relationship between an increase in the negative summating potential (-SP) and the results of caloric tests was examined in 35 patients with unilateral Menière's disease. The -SP was recorded by extratympanic electrocochleography. The quantitative bithermal caloric test was performed by irrigating with cool (30 degrees C) and hot (44 degrees C) water. An increased -SP was recorded in 20 of 35 patients (57%). Abnormal unilateral weakness (UW) on the involved side and abnormal directional preponderance (DP) to the involved side were observed in 16 of 35 (46%) and in 4 of 35 patients (11%), respectively. No significant correlation was found between an increased -SP and an abnormal UW and DP in Menière's disease.
对35例单侧梅尼埃病患者进行了负和电位（-SP）升高与冷热试验结果之间关系的研究。通过鼓室外电耳蜗图记录-SP。采用冷（30℃）水和热（44℃）水冲洗进行定量双侧冷热试验。35例患者中有20例（57%）记录到-SP升高。35例患者中分别有16例（46%）患侧出现异常单侧眼震减弱（UW），4例（11%）患侧出现异常向地性优势偏向（DP）。在梅尼埃病中，未发现-SP升高与异常UW和DP之间存在显著相关性。
