title: [Lexical tone perception and quality of life in nurotron cochlear implant users].
abstract: OBJECTIVE
  To investigate the lexical tone perception and quality of life of Nurotron cochlear implant users.
  
  
  METHODS
  Forty-nine adult cochlear implant users participated in this study. Mandarin tone identification test developed by Beijing Institute of Otolaryngology was used to evaluate the tone perception. Nijmegen cochlear im plantation questionnaire (NCIQ) was administered to quantify the quality of life.
  
  
  RESULTS
  (1) The average scores of tone perception in quiet was 67.26%. The tone perception rates under quiet condition for all cochlear implant recipients were higher than the opportunity level. (2) The average scores of tone perception under noisy condition was 51.92%. Exc ept for two recipients, the tone perception rates under noise condition for the rest recipients were better than chance. (3) The confusion patterns of tone recognition showed that Tone 3 was the easiest tone to perceive. (4) The postimplant scores for the total , basic sound perception, advanced sound perception, speech pro duction, self-esteem, activity and social interactions of NCIQ were 55.4, 72.4, 54.0, 63.4, 50.7, 47.3 and 44.7, respectively.
  
  
  CONCLUSIONS
  The Nurotron cochlear implant users had the ability for lexical tone perception and had an improvement in quality of life after cochlear implantation.
