Introduction:

Tests to evaluate receptive passive vocabulary show differences in performance which permit conclusions about speech perception of spoken language. For the group of children with congenital deafness and cochlear implants (CI), the individual testing of passive vocabulary at the age of enrollment is necessary in order to assess the conditions for school education.

Methods:

We present the results of 165 subjects tested with the subtest “Passive Vocabulary” from the “Marburger Sprachverständnistest für Kinder”, collected during our clinical routine. All children were between 60 and 96 months old, with congenital profoundly deafness and CI on both sides. They had a hearing age calculated from the first CI between 32 and 84 months. The evaluation is carried out as ranks of percentile, compared to hearing peers and divided in three groups (Gr): Gr.1. Medium Age of Implantation (MAI) 0.73 years (J.) [Minimum (Min.) 0.42J./Maximum (Max.) 0.92J.] N = 50; Gr. 2 MAI 1.43J. [Min.1.00J./Max. 1.92J.] N = 72; Gr. 3 MAI 2.55J. [Min. 2.00J./Max. 3.33J.] N = 43.

Results:

The group comparison shows that on average the children implanted after their second year of life achieved significantly poorer results in the passive vocabulary test.

Conclusions:

The result shows that congenitally deaf children with an initial supply with CI after the second year of life have, on the average, lesser literacy skills that restrict the linguistic comprehension in school.
