Impedance for different electrode types

3 May 2022 | | Auditory Implants | Access resistance, Cochlear implants, Faraday resistance, Polarization impedance, Warburg capacitance

Measuring cochlear implant (CI) electrode impedances is common in CI programming appointments to measure the integrity of the implant e.g. whether there are any open or short electrodes. This is because impedance measures the flow of current between intra and...

Early cochlear implant activation and its effects on the cochlea

3 March 2021 | | Auditory Implants, Paediatric ENT | Electrode impedance, Fibrosis, Minimal invasive cochlear implantation technique, One-day activation

In this article, Alhabib et al consider the changes to electrode impedance with early device activation (day one) compared to conventional activation (day 30). Activation at day 30 is a cautious approach, which has been popular for many years. However,...

Objective testing for Eustachian tube dysfunction

9 October 2017 | | accuracy, eustachian tube, impedance, test, tubomanometry

Eustachian tube dysfunction (ETD) is typically diagnosed based on subjective symptoms and examination leading to wide variation in its diagnosis and management. The search for an objective test has looked at ways of measuring the passage of air through the...
