Cochlear Implant Outcomes: Assessing Success and Challenges

The cochlear implant is a device that offers the possibility of restoring auditory perception and speech understanding to individuals with severe sensorineural hearing loss who do not benefit from hearing aids. The results achieved by cochlear implant users can vary widely depending on a number of factors. Variability in results depends on factors such as age at implantation, duration of hearing loss, preimplantation hearing experience, residual hearing, use of bilateral, bimodal, or unilateral cochlear implants, underlying pathology causing the hearing loss, and additional disabilities. This section discusses the outcomes of cochlear implantation and the factors that influence these outcomes.
