ABSTRACT

OBJECTIVE@#To investigate the clinical experiences and access the auditory performance and speech intelligibility of cochlear implantees with inner ear malformations.@*METHOD@#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).@*RESULT@#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.@*CONCLUSION@#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.
