INTRODUCTION: Due to the great number of affected people, hearing loss is considered a serious social, economic and public health problem. Hearing aids and cochlear implants are the primary devices used as palliatives for people with hearing loss, and cochlear implants are often the only option in cases of severe to profound hearing impairment. This paper covers both technological and socio-economic aspects of cochlear implant, which is considered as one of most recommended treatments to alleviate severe to profound hearing loss. METHODS: Brazilian unified health system data is used to display qualitative and quantitative analysis impact on Brazilian population and government. A state-of-art review based on scientific literature and manufacturer data is provided, as well as perspectives for the next cochlear implant generation. CONCLUSION: There is potential and demand for evolutions in current implants. Early implantation is beneficial for patients and society, compensating the costs economic and socially. However, public programs need to adapt in order to efficiently attend the increasing affected population.
