Cochlear Implant Impedance Fluctuation in Ménière's Disease: A Case Study

Conclusion: Electrode impedances in the ear with MD showed a variation pattern similar to that found in the hearing fluctuation characteristic of the disease. These findings raise the possibility that the same physiological mechanisms of hearing fluctuation may be responsible for intracochlear electrode impedance changes. We hypothesize that impedance fluctuation is because of changes in the permeability of the blood–labyrinth barrier because of cyclic immune activity in the inner ear which alters the electrical resistance between scala tympani and blood.
