A Comparison of Linguistic Skills between Persian Cochlear Implant and Normal Hearing Children

In this work, it has been tried to determine the level of language skills of children with cochlear implant (CI) in comparison with normal hearing (NH) age mates. Test of Language Development was administered to 30 prelingual, severe-to-profound CI children between the ages of 5 to 8. The obtained scores were compared to a Persian database from scores of normally hearing children with the same age range. Results indicated that in spite of great advancements after the gain of hearing, CI children still lag behind their hearing age mates in all aspects of language.
