title: [The change of the auditory function in children with cochlear implant].
abstract: OBJECTIVE
  Study the change of the auditory function in children with cochlear implant in different periods.
  
  
  METHODS
  This study compared the Nucleus group and the Clarion group in 47 children after cochlear implantation, discussed the auditory change in different periods after surgical procedures and by the Listening Progress Profile (LIP) of Nottingham University.
  
  
  RESULTS
  The average scores of LIP before the operation and after 3 months, 6 months and 12 months were (8.5 +/- 9.9), (35.0 +/- 8.6), (39.0 +/- 2.4), (40.0 +/- 2.9) in Nucleus group and (5.6 +/- .5), (28.1 +/- 13.4), (34.4 +/- 9.2), (39.8 +/- 3.5) in Clarion group respectively. The improvement of auditory function was significant in the initial 3 months after switch-on but slower from the 3rd to 12th month.
  
  
  CONCLUSIONS
  The testing outcomes of auditory function in both Nucleus group and Clarion group are all close to the full score 1 year after switch-on. The auditory function can be improved in different degrees after the cochlear implantation in children with congenital deafness.
