Triphasic Stimulation in Cochlear Implants: A Comparative Evaluation of Programming Levels, Speech Intelligibility, and Spectral-Temporal Resolution in Users With and Without Inner Ear Malformations

Triphasic stimulation substantially enhances speech intelligibility in CI users with IEMs while offering no perceptual advantage-and a slight disadvantage-for users with NIE. Programming CIs with triphasic pulses may therefore be a valuable strategy for malformation cases, enabling greater loudness comfort and improved communication without resorting to electrode deactivation or reduced current levels.
