Clinical perspective on hearing preservation in cochlear implantation, the University of Iowa experience

Bruce J Gantz et al. Hear Res. 2022 Dec.

Abstract

Preservation of residual acoustic hearing has emerged as an important concept for those individuals undergoing cochlear implantation with residual low frequency hearing. Acoustic plus electric speech processing improves hearing outcomes in quiet, enables melody recognition, preserves spatial hearing if there is acoustic hearing in both ears and significantly improves hearing in noise. The development of our experience with acoustic plus electric processing is reviewed along with clinical trials and patient outcomes that our team has documented over the past twenty years.

Keywords: Acoustic + electric processing; Cochlear implant; EAS; Hearing preservation; Hybrid Cochlear Implant.
