Cochlear implants (CIs) are surgically implanted devices that restore hearing in individuals with severe to profound sensorineural hearing loss. By converting sound into electrical signals that stimulate the auditory nerve, CIs have dramatically improved hearing rehabilitation. Over the past two decades, CI implantation rates have surged, driven by advancements in device design, minimally invasive surgical techniques, and refined programming strategies, all contributing to enhanced safety and efficacy. These technological developments have also broadened CI candidacy, now including individuals with greater residual hearing and infants under one year old. This overview examines current CI designs, their historical evolution, and future prospects. It highlights key figures in otology and CI design who have shaped this technology's progress. Recognizing the pivotal role of clinical and surgical anatomy, physiology, and treatment methodologies, this article underscores the significant technological advancements that have benefited CI recipients, paving the way for future innovations. Keywords: Cochlear implant, Future designs, Deafness, Hearing Rehabilitation.
