Impedance measurements in the diagnosis of Meniere's disease

Meniere's disease is discussed in terms of diagnostic difficulties, histological findings and treatments pointing to the use of impedance techniques with this condition. Ten subjects were given a questionnaire, regarding the symptoms experienced at the time of testing and impedance measures were conducted. Acoustic impedance values were higher in 80% of the affected ears when compared to the unaffected ears. Four of these values were more than double those in the unaffected ears and three were above normal limits. Therefore, increased endolymphatic pressure appears to be reflected in the test results. It is felt that impedance techniques should be.included in the test battery for the diagnosis of Meniere's disease.
