Relationship between results of electrocochleography and caloric test in Menière's disease.
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.
