Contemporary Cochlear Implantation: Technology, Outcomes, and Future Directions

This chapter examines the state of the art in cochlear implantation, reviewing advances in electrode design, signal processing algorithms, and residual hearing preservation. It synthesises outcomes data across paediatric and adult populations, addresses candidacy expansion to single-sided deafness and broader audiometric profiles, and discusses the horizon of fully implantable devices, optical cochlear implants, and auditory brainstem stimulation.
