Researchers discover details to improve mapping of electric-acoustic stimulation hearing devices

Evan Nix, MD, and colleagues within the division of Otology/Neurotology and Cranium Base Surgical procedure and the division of Auditory Analysis within the UNC Division of Otolaryngology/Head & Neck Surgical procedure have been finding out the practical acoustic listening to areas of cochlear implant recipients.

Of their newest examine, they discovered that roughly 60% of cochlear implant recipients with listening to preservation had a number of electrode contacts within the practical acoustic listening to area.

For individuals who listened with an electric-acoustic stimulation (EAS) gadget, there was a big affiliation between speech understanding in noise and proximity of the electrode array to the practical acoustic listening to area in both the basal or apical course.

These knowledge have scientific implications for electrode array choice for cochlear implant candidates with practical acoustic listening to and for mapping of the EAS gadget.

The info help collection of an electrode array that will likely be positioned on the higher fringe of the practical listening to area to keep away from electrical on acoustic interference. Additionally, the position of the electrode array for a person affected person might be included into the customized mapping of the EAS gadget.

The examine is printed within the journal Otology & Neurotology.
