Relative Efficiency of Cochlear Hydrops Analysis Masking Procedure and Cervical Vestibular Evoked Myogenic Potential in Identification of Meniere’s Disease

Table 1

Mean and standard deviation for amplitude and asymmetry ratio of cervical vestibular evoked myogenic potentials and latency difference of wave V between click alone and click with 500 Hz high-pass masking pink noise in healthy individuals and individuals with Meniere’s disease.

Population		cVEMP		CHAMP
		Amplitude (in μV)	Asymmetry ratio (in %)	Wave V latency difference (in ms)
Individuals with; Meniere’s disease	Affected ear	106.96 (74.00)	42.78 (22.48)	0.14 (0.10)
	Unaffected ear	124.92 (60.96)		0.89 (0.11)
Healthy individuals	Affected matched	151.31 (63.74)	16.19 (4.90)	0.96 (0.17)
	Unaffected matched	154.20 (63.99)		0.93 (0.15)

Note: “affected matched” and “unaffected matched” ears in healthy individuals are referred to the same side ears of the healthy individuals as that of individuals with Meniere’s disease that were affected and not affected by the disease, respectively. The values within the brackets represent standard deviation.
