Abstract ABSTRACTIntroduction: The results obtained in the speech perception and oral language acquisition in children using cochlear implants vary. The main aspects pointed to justify these results are age at surgery, time of sensory deprivation and time of cochlear implant use. The physiological changes in the hearing system, related to age, reflect in the auditory evoked potentials, thus, it is possible to determine the relation in these changes and the development of behavioral hearing skills. Goal: To identify and verify the characteristics of complex P1-N1-P2 of long-latency auditory evoked potentials, in cochlear implant users for a long time, and correlate them with speech perception performance, and secondarily, with other variables related to cochlear implants. Material and Method: Thirty cochlear implant users who were implanted in the age range 2 - 4 years, from both genders, with the time of use electronic device ranging from 6 to 14 yrs, will participate in this study. Complex P1-N1-P2 of long-latency auditory evoked potentials will be researched with the /da/ speech stimulus and speech perception assessed with sentence list. The procedures will be performed in free field. | |
