To determine whether cochlear hydrops analysis masking procedure (CHAMP) has diagnostic value in patients with definite Ménière's disease (MD) comparing the validity index of CHAMP those electrocochleography (ECoG).A prospective study.Tertiary referral center.One hundred eight were classified into 3 groups: "definite MD" group (MD group, n = 47); "non-MD" (n 41) other vestibular diseases including neuritis, and benign paroxysmal positional vertigo; control 20), which included without dizziness.CHAMP extratympanic ECoG performed all patients.Sensitivity, specificity, definitions abnormal values less than 0.3 ms latency delay (0.5 kHz high pass noise [HPN]-click alone) 0.95 compound amplitude ratio (click alone-0.5 HPN/click 0.4 for summating potential/action potential ECoG.The mean MD significantly differed from these groups, whereas did not. In ECoG, sensitivity was as low 21%, specificity 97%, accuracy 62%. Sensitivity, 64%, 98%, 80%, respectively, 91%, 83%, 88%, ratio. The higher corresponding ECoG.CHAMP is more valuable detection ECoG.
