[Application of the electrocochleogram in Menière's syndrome].

The results of evoked potentials (ECOG and ABR) in 92 patients with complaints of dizziness and vertigo were analysed. There were 69 cases of Menière's syndromes, among which 45 cases (75%) showed increase of the summating potentials. In 22 cases the SP/AP rate exceeded 0.37 of 23 cases of vertebral basilar arteria TIA, one case showed negative wave SP increase, one case showed SP/AP ratio exceeding 0.37 and 3 cases showed prolonged latency of I wave in ABR. It was pointed out the simultaneous use of ECOG and ABR would be of help in identifying the most probable cause of dizziness and vertigo and this method would be worthy to be used on a much broader scale.
