“…This finding may be explained, among several hypotheses, by the time and consolidation of this research front on the international scene, especially in countries like the United States and Germany 5 .…”

“…One of the main, if not the main target of auditory rehabilitation of the cochlear implant is the development of language (ie, the ability to abstract and symbolize linguistic signs in a meaningful and contextualized way, allowing interaction and communication between people of the same linguistic community 7 ) in oral modality, especially when it comes to children with pre-lingual auditory hearing loss [7][8][9][10] .Following this concern, researchers have obtained important findings about what variables and processes are related to the language development of these children 10 , conditions that could improve auditory skills 5 and possible relations that these establish with the development of expressive skills, such as speech production 6,11 .…”

“…Laterality, it is called bilateral when both ears are affected. The pre-lingual expression, in turn, indicates that hearing loss has occurred prior to the acquisition of language 4,5 . This diagnosis constitutes an important component for making decisionsof rehabilitation in order to direct the clinical management and the indication of electronic devices for deafness, such as the cochlear implant [4][5][6] .…”

“…Given the technological potential that it offers, this device has been recommended mainly for severe/profound hearing loss bilateral neurosensorial conditions (who not obtained gains from conventional hearing aids), but studies have also shown the benefits in other auditory pathologies (such as Auditory Neuropathy Spectrum Disorder) and multiple deficiencies cases 5,6 .…”

“…The uni-terms or keywords applied in this review were: "cochlear implant", "auditory recognition", "recognition", "speech", "speech production" and "language", which were exchanged with syntaxes/ expressions of three to four terms for electronic Considering the impact on language development and implications for the individual's quality of life, this study highlights sensorineural type hearing loss, severe-profound, bilateral and pre-lingual 4,5 . Hearing loss can be defined as sensorineural if damage is identified in the auditory nerve or hair cells in the cochlea (present in the inner ear).…”
