Sig. (2-tailed), Exact Sig. (1-tailed)]. the above results, in agreement with Bille et al. study, indicated that children with inner ear malformation over time perform equally to children without inner ear malformation, but at a slower rate of improvement; this is in accordance with Eisenman et al.’s [3] observation that children with malformed cochlea improved more slowly than did their matched control subjects. therefore, parents should be aware of the time needed for their children to achieve the best performance after CI of the malformed cochlea and actively support this long effort.
