title: Speech perception in adolescents with pre-lingual hearing impairment with cochlear implants.
abstract: Profound hearing loss is a disability that affects personality and when it involves teenagers before language acquisition, these bio-psychosocial conflicts can be exacerbated, requiring careful evaluation and choice of them for cochlear implant.
  
  
  OBJECTIVE
  To evaluate speech perception by adolescents with profound hearing loss, users of cochlear implants.
  
  
  METHODS
  Prospective.
  
  
  METHODS
  Twenty-five individuals with severe or profound pre-lingual hearing loss who underwent cochlear implantation during adolescence, between 10 to 17 years and 11 months, who went through speech perception tests before the implant and 2 years after device activation. For comparison and analysis we used the results from tests of four choice, recognition of vowels and recognition of sentences in a closed setting and the open environment.
  
  
  RESULTS
  The average percentage of correct answers in the four choice test before the implant was 46.9% and after 24 months of device use, this value went up to 86.1% in the vowels recognition test, the average difference was 45.13% to 83.13% and the sentences recognition test together in closed and open settings was 19.3% to 60.6% and 1.08% to 20.47% respectively.
  
  
  CONCLUSIONS
  All patients, although with mixed results, achieved statistical improvement in all speech tests that were employed.
