ABSTRACT

Objective To evaluate the auditory and verbal abilities of cochlear implantees using question_naires ,to explore basic rules of the development of auditory and verbal abilities ,and to analyze their relationships with some influencing factors .Methods A retrospective analysis of 107 cases of pre-lingually deaf children with cochlear implantation was conducted with Infant-Toddler Meaningful Auditory Integration Scale/Meaningful Audi_tory Integration Scale (IT -MAIS/MAIS) ,categories of auditory performance (CAP) and speech intelligibility rat_ing (SIR) for the evaluation of auditory and verbal abilities .An analysis was performed to assess influencing fac_tors ,such as postoperative time ,age at implantation ,physical age at follow -up ,time with hearing aids before im_plantation .SAS 9 .1 .3 was used in statistical analysis .ResuIts A total of 107 pre-lingually deaf children (48 males and 59 females) participated in this study .The postoperative time ranged from 0 to 49 months ,with an average of 9 .0 ± 10 .9 months .The results showed the postoperative time and age at implantation had significant influences on the scores of IT -MAIS/MAIS ,and postoperative time and physical age at follow -up had significant influences on the scores of CAP/SIR (P0 .05) .ConcIusion The ages at implantation ,postoperative time and physical age had significant influences on the auditory and verbal abilities of pre-lingually deaf children with cochlear implanta_tion .Further studies are needed to explore their relationships with hearing aids usage before implantation .
