Questionnaire Evaluation Of Auditory And Verbal Ability Of Cochlear Implantees And Analysis Of Influencing Factors

Objective:To evaluate the auditory and verbal abilities of cochlear implantees with questionnaires, explore basic rules of the development of auditory and verbal abilities, and analyze their relationships with some influencing factors.Methods:A prospective study was conducted on 42 cases of pre-linguistic deaf children with cochlear implantation and a retrospective analysis on 121 cases, Infant-Toddler Meaningful Auditory Integration Scale/Meaningful Auditory Integration Scale (IT-MAIS/MAIS), categories of auditory performance (CAP) and speech intelligibility rating (SIR) was applied in the evaluation of auditory and verbal abilities. A retrospective analysis was conducted on 23 cases of post-lingual patients with cochlear implantation. CAP and SIR were applied in the evaluation of auditory and verbal abilities. An analysis was performed on the influencing factors. IBM SPSS Statistics 19 was used in statistical analysis.Results:Prospective study on children showed scores of IT-MAIS/MAIS and CAP/SIR increased with the postoperative time (P<0.05), and they are not significantly related with age at implantation, special cases (including cochlear malformation, virus infection during pregnancy, Family history of deafness and auditory neuropathy), time with hearing aids before implantation (P>0.05). Retrospective analysis on children showed scores of IT-MAIS/MAIS and CAP/SIR were significantly correlated with postoperative time, age at implantation, and physical age (P<0.05), and were not significantly correlated with time with hearing aids before implantation (P>0.05). Retrospective analysis on post-lingual patients showed the average score of CAP was 6.13, and it was not significantly correlated with the duration of hearing ioss, the postoperative time or time with hearing aids before implantation (P>0.05), and the average score of SIR was 4.91.Conclusion:Auditory and verbal abilities of pre-linguistic deaf children with cochlear implantation were significantly correlated with postoperative time, age at implantation, and physical age. Further study shall be made to explore their relationships with special cases and time with hearing aids before implantation. Retrospective analysis on post-lingual cochlear implantees showed that CAP score was not significantly correlated with the above three factors. This may due to the low accuracy of CAP or the small sample size in the present study. SIR was not suitable for the evaluation of post-lingual cochlear implantees.
