The pathological hallmark of Mé niè re's disease is endolymphatic hydrops, which can lead to an increase in basilar membrane stiffness and, consequently, an acceleration of the traveling wave of sound. The cochlear hydrops analysis masking procedure (CHAMP), which is an auditory brainstem response test masked at various frequencies with high-pass noise masking, uses the principle of the traveling wave velocity theory to determine the presence of endolymphatic hydrops.Purpose: To review the previous results of the CHAMP, expound the principle and key indicator of this procedure, and discuss its clinical significance in diagnosing Mé niè re's disease.Methods: A narrative review was performed, revisiting the principles of the CHAMP test, its procedures, and the results of its clinical application in diagnosing Mé niè re's disease.According to the published literature, CHAMP has a specificity of 31% to 100%, a sensitivity of 28% to 100%, and a diagnostic accuracy of 30% to 100% for the diagnosis of Mé niè re's disease, including patients with definite, probable, or possible Mé niè re's disease in various studies. These inconsistent results were due to subject inclusion criteria, variable settings, waveform identification, and other factors. Nevertheless, as an electrophysiological technique, CHAMP may have a relatively high diagnostic value in patients with a definite Mé niè re's disease.Conclusions: CHAMP is still potentially useful for studying the pathophysiology of hydropic ear diseases since the procedure can measure the traveling wave velocity of the basilar membrane in the era of imaging to detect endolymphatic hydrops for Mé niè re's disease.
