OBJECTIVE: To seek a convenient and effective method through subjective psychophysical measurements and CAP/SIR assessment. To compare the discrimination of rehabilitation between post-lingual and pre-lingual deafened patients. METHOD: Thirty-one post-lingual cochlear implantees and 59 pre-lingual cochlear implantees, the warble tone and CAP/SIR were assessed. The discrimination of threshold levels, comfortable levels and dynamic range between post-lingual and pre-lingual deafened patients in same electrodes were compared. RESULT: There was no statistic difference in warble tone, T-levels, C-levels and dynamic range in same electrodes implant after 6 months implant (P>0.05). The score of CAP and SIR in post-lingual deafened patients were more prominent. CONCLUSION: CAP and SIR is a kind of convenient and effective method to assess the ability of aural and oral. There was no discrimination in warble tone, T-levels, C-levels and dynamic range in same electrodes implant, but the ability of aural and oral in post-lingual deafened patients were more prominent.
