Effects of Insertion Depth and Modiolar Proximity on Cochlear Implant Speech Recognition Outcomes With a Precurved Electrode Array
These data suggest that both apical cochlear coverage and modiolar proximity independently confer speech recognition benefit with a precurved array. However, these benefits are mutually exclusive for current precurved array designs as a deeper basal insertion depth results in greater apical coverage but lateralization of electrodes away from the modiolus in the basal turn. Future work is needed to elucidate mechanisms behind these findings that may motivate electrode array design modifications to further optimize outcomes for CI users.
