title: [Cochlear implantation and rehabilitation in prelingually deafened adolescents and young adults].
abstract: OBJECTIVE
  To investigate the outcomes of prelingually deafened adolescents and young adults receiving cochlear implantation (CI).
  
  
  METHODS
  Thirty-three patients with prelingual deafness aged 7-33 years at the time of CI were followed up for 4 years. The Speech Discrimination Score (SDS) was tested using disyllabic words and short sentences with close-set and open-set, respectively.
  
  
  RESULTS
  After appropriate mapping, sound field audiometry with warble tone showed that the warble tone threshold average (WTA) of the patients reached 25-41 dBHL, with a mean threshold of 28.62∓2.37 dBHL. At 1 year after the operation, the mean value of SDS was 70.03% in close-set word list with lip-reading and 61.18% without lip-reading, and was improved to 82.12% and 72.67% at 4 years, respectively. In open-set word list, the mean value of SDS was 77.94% with lip-reading and 67.85% without lip-reading. The safety and the benefits-cost evaluation of CI for prelingually deafened school age children and adolescents had been recognized by 90.9% of the families involved.
  
  
  CONCLUSIONS
  These patients can obtain appropriate speech discrimination scores with improved quality of life after CI.
