Hearing Physiology and Cochlear Implantation
Abstract: In this talk, we will discuss the physiology of hearing and cochlear implantation. Cochlear implants provide electrical hearing via an external processor that transduces acoustic information and feeds encoded information to an implanted receiver-stimulator that electrically activates residual fibers of the auditory nerve. Prelingually deafened children acquire speech and language through central plasticity that results from stimulation by auditory prostheses. Postlingually deafened children and adults—as well as those with severe to profound hearing loss, who derive marginal benefit from hearing aids—benefit from cochlear implantation by recapturing acoustic-phonetic perception to recognize speech. Congenital deafness occurs in approximately 1 in every 1000 children, at least 60% of whom have hereditary causes for their deafness.
