In the period immediately following the implantation of a cochlear implant electrode array within the cochlear environment, the power required to stimulate the auditory nerve at preset current levels increases. This rise is due to increases in electrode impedance which in turn is suggested to be a result of tissue growth around the electrode array. The foreign body response initiated by the immune system encapsulates the array in a matrix of fibrous tissue, separating the electrode array from the rest of the body. A second change in electrode impedance occurs with the onset of electrical stimulation. A transitory reduction in impedance has been recorded in animals and humans after stimulation of electrodes. Impedance returns to pre-stimulation levels following the cessation of stimulation. It was suggested that these changes in impedance with stimulation were also related to the tissue growth around the electrode array. A more thorough understanding of the interface was required to ascertain these concepts.

In the United States, permanent hearing loss affects approximately 3 newborns in 1,000 making it the most common birth defect. Current widespread use of universal newborn hearing screening has resulted in an average age of identification of hearing loss of 2-3 months. As the population of children who are identified early in life and fitted with cochlear implants (CI) grows, speech-language pathologists (SLPs) are likely encounter clients from this population. However, the majority of SLPs are not educated as to the various modes of communication that can be used with children with CI as they learn spoken language. The focus of this review is to provide SLPs with an evidence-based resource to guide their decision-making regarding appropriate communication mode for children with CI. / text
