Longitudinal Development of Verbal and Nonverbal Intelligence After Cochlear Implantation According to Wechsler Tests in German-speaking Children: A Preliminary Study.

The results, despite the small sample size, clearly suggest that children with CIs can achieve intellectual abilities comparable to those of their normal-hearing peers by around the third year after initial CI fitting, and they continue to improve over the following 2 years. We recommend further research focusing on verbal IQ assessed around the age of school entrance to be used as a predictor for further development and for the establishment of an individual educational program.
