This study prospectively analyses electrocochleography (ECoG) recordings obtained from ears demonstrating symptoms highly suggestive of Meniere's disease. Comparison is made with ECoG recording from ears in which the diagnosis of Meniere's is considered unlikely (control ears). Electrocochleograph recordings were made through a transtympanic recording needle, situated in the round window niche....
The technique of transtympanic electrocochleography was initially developed as an objective hearing threshold test by Eggermont. Gibson et al. (1977) claimed that an enlarged direct current component of the action potential (AP) called the summating potential (SP) is an indication of endolymphatic hydrops, later confirmed by Coates who proposed an SP/AP ratio measure. This led to numerous publi...
Audiological and vestibular testing plays an important role in diagnosis of Menière’s disease,as disease per se and as staging diagnosis. A battery of tests are recommended in order to have a better evaluation of the disease. Audiological testing includes pure tone audiometry, with highlights of bone conduction especially in acute episodes of Menière’s disease, speech audiometry and glycerol te...
