Correlation of Cochlear Hydrops Analysis Masking Procedure and Electrocochleography in Meniere’s Disease

Abstract

Meniere’s disease is an idiopathic inner ear disorder which is characterized by episodes of vertigo, fluctuating hearing loss, aural fullness and tinnitus or a combination of these symptoms. Diagnosing Meniere’s disease is always a matter of controversies because of its so frequent fluctuation of symptoms. Recent researches are focused on Cochlear hydrops analysis masking procedure (CHAMP) and electrocochleography (ECochG), as these tools are more reliable. The present study was undertaken to investigate the correlation between these two tests to diagnose Meniere’s disease and also. The study was conducted on two groups, individuals with Meniere’s disease (experimental group) and individuals with normal hearing (control group). ECochG and CHAMP were administered on both the groups. Results revealed that, in CHAMP, wave V latency was significantly shorter in experimental group as compared to control group. In ECochG, there was a significant difference between the two groups with respect to(a) longer latency and larger amplitude of action potential (AP) in experimental group, (b) larger amplitude of summating potential (SP) in experimental group and c) larger SP/AP amplitude ratio in experimental group. Thus it can be concluded that both test give reliable results to diagnose Meniere’s disease, but the correlation of both the tests was found to be low negative. Therefore, along with these two tools, other aspects like ENT confirmation and other tests should also be administered for confirm diagnosis of Meniere’s disease.
