The ability to make oneself understood is critical to most human interaction, and as such, the failure to develop fully intelligible speech may result in a significant handicap especially in the child in learning phase. World literature has demonstrated improved speech intelligibility and speech perception as well as a good development of communication skills in prelingual profound sensorineural hearing loss (SNHL) children after cochlear implantation. The literature considered as universally-accepted the usefulness/effectiveness of unilateral early cochlear implantation in severely-profoundly deaf children with or without associated disabilities. In fact this procedure, for children implanted very early it appears that progress toward intelligible speech is more rapid and ensures physiological development of 'learning the language, although slower, even in children with disabilities associated with deafness. The aim of this review was to analyze data literature about audiometric characteristics and speech intelligibility/perception after implantation comparing the results with those described by different authors showing the methods of evaluation used as audiometric tests, language measures -Test for Auditory Comprehension of Language-Revised (TACL-R); Speech/sign interview; Narrative task; WISC-III Similarities subtest; Speech interview- and questionnaires. Recent studies have correlated various tests and questionnaires administered after implantation (1, 3, 6, 12 and 18 months by activation), such as meaningful auditory integration scale (MAIS), meaningful use of speech scale (MUSS), categories of auditory performance (CAP), and speech intelligibility rating (SIR). The results obtained after surgery are linked, as well as the age of the patient, cochlear implant technology and amount of implant use, even to the substrate cultural family especially in the post implant.
