Meniere's Disease and the Summating Potential: II. Vestibular Test Results

Arch Otolaryngol. 1981;107(5):263-270. doi:10.1001/archotol.1981.00790410001001
Abstract

• Results of electronystagmograhic (ENG) position and bithermal caloric tests from patients with abnormally enlarged summating potentials (SPs) were compared with results from a unilateral weakness (UW)-matched ENG-comparison group and with a group of patients with unilateral cochlear deficits and dizziness but without enlarged SPs. The patients with enlarged SPs had a significantly higher incidence of caloric UW on the involved side than did the patients with cochlear deficits but without enlarged SPs. Also, the patients with SP enlargement had a significantly higher incidence of directional preponderance toward the involved side than did either of the comparison groups. Across-group differences in position test results were predictable from the caloric test results, but these differences were not statistically significant.
