title: Use of the telephone in prelingually deaf children with a multichannel cochlear implant.
abstract: OBJECTIVE
  To assess progress in the use of the telephone in a group of prelingually deaf children after cochlear implantation.
  
  
  METHODS
  Tertiary referral pediatric cochlear implant center in the U. K.
  
  
  METHODS
  A prospective study was undertaken on a consecutive group of 150 congenital and prelingually deaf children up to 5 years after implantation. The study group was confined to prelingually deaf children aged less than 7 years at the time of implantation. No child was lost to follow-up, and there were no exclusions from the study. At the time of the study, 129 children had reached the 1-year stage, and 91, 68, 40, and 23 had reached the 2-, 3-, 4-, and 5-year intervals, respectively.
  
  
  METHODS
  A specifically designed profile was used to assess the telephone use of the implanted children. Regression analysis was used to assess the correlation between the results of the telephone profile with the outcomes of the Iowa sentence test and connected discourse tracking.
  
  
  RESULTS
  After implantation, prelingually deaf children showed significant progress in telephone use over time, not reaching a plateau at the 5-year interval (median score 27 with maximum score available 34). The results of the telephone profile showed significant correlations with the other tests of speech perception (correlation coefficients from 0.47 to 0.79, all statistically significant p < 0.0001).
  
  
  CONCLUSIONS
  The telephone profile provided a useful method of monitoring children's telephone use. The profile was easily administered, and it was sensitive in assessing the progress of prelingually deaf children with cochlear implants. Outcomes from the profile were highly correlated with results from other widely used closed- and open-set tests.
