Auditory brainstem response (ABR) is routinely used in neurological and otological investigation field. Noninvasive electrophysiology technique based on the principle of elecrtoencephalography (EEG), ABR provide objective and reproductible information on the hearing function from the cochlea to the brainstem.
Thanks to it’s collaboration with Advanced Bionics, Cochlear, MED-EL and Neurelec, Echodia has developed a technology enabling the monitoring of eABR.
The eABR is a measurement of the ABR using an electrical stimulus coming from the implant. It enables to establish if the cochlear implant is working, in other words, that the auditory nerve responds correctly to the electrical stimulation.
An electrical stimulus is sent into the patient’s implant while the Echodia device is collecting the electrical activity using electrodes. The response is avaible in real time on the Echosoft software.
We developed a specific tool to measure eABR for implants of each brands.
Two Echodia devices enable eABR: Elios, a multifunction comprehensive tool for hearing assessment and Elite, an equipment dedicated to evoked potentials.
