[Study of categories of auditory performance and speech intelligibility rating of post-lingual cochlear implantes]

To evaluate the verbal communication skills of post-lingual cochlear implantees with categories of auditory performance (CAP) and speech intelligibility rating(SIR), and to explore their relationships with the duration of hearing loss, the postoperative time and preoperative hearing aid usage.

A retrospective analysis was conducted on 23 cases of post-lingual patients with cochlear implantation. CAP and SIR were applied in the evaluation of verbal communication skills. IBM SPSS Statistics 19 was used in statistical analysis.

The average score of CAP was 6.13, and statistical analysis showed CAP score was not significantly correlated with the duration of hearing loss, the postoperative time or the time of wearing a hearing aid preoperatively. The average SIR score of all these post-lingual patients was 4.91.

It showed that CAP score was not significantly correlated with these 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.
