title: [A questionnaires study on cochlear implantation in patients with malformed inner ear].
abstract: OBJECTIVE
  To investigate the clinical experiences and access the auditory performance and speech intelligibility of cochlear implantees with inner ear malformations.
  
  
  METHODS
  A retrospective study was performed on the surgical characteristics and the mapping characteristics after implantation of patients who received mult-channel cochlear implantation from 2000 to 2007 in Xijing Hospital. Matched with normal implanted, rank -sum test was performed to compare scores of categories of auditory performance (CAP) and speech intelligibility rating(SIR).
  
  
  RESULTS
  After the regular rehabilitation, the long term follow-up of the auditory performance and speech intelligibility were very positive. There was no significant difference between normal group and malformations group.
  
  
  CONCLUSIONS
  The cochlear implantation can be performed safely in patients with malformed inner ear. The results suggest that cochlear implantation could also provide long-term benefits to those malformed inner ear cases.
