A control group with normal cochlea was also tracked. Regular assessments, including aided hearing threshold, categories of auditory performance (CAP), and speech intelligibility rating (SIR), were conducted every 6\u2009months for the first 2\u2009years post\u2010CI and annually thereafter. Speech recognition was tested for children who could cooperate with it.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The aided hearing threshold of IP\u2010I children had improved significantly from 90.51\u2009dB HL before CI to 47.02\u2009dB HL in the sixth\u2010month post\u2010CI, and it had further improved to 26.27\u2009dB HL after more than 48\u2009months post\u2010CI. Meanwhile, their median CAP scores had improved from 0 to 6.5 and median SIR scores from 1 to 4 over the same period. There was no significant difference in the improvement of mean aided hearing thresholds over time between the IP\u2010I and control groups postoperation. However, IP\u2010I children showed slower progress in CAP and SIR scores and had lower recognition rates for monosyllabic and disyllabic words compared with the control group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Children with IP\u2010\u0399 showed continuous but slower improvement in auditory and speech capabilities post\u2010CI compared to those with normal cochlea.
