Language evaluation in children with pre-lingual hearing loss and cochlear implant

Area of Science:

• Pediatric audiology
• Speech-language pathology
• Developmental pediatrics

Background:

• Cochlear implants (CI) significantly improve oral language acquisition in children with severe-to-profound prelingual hearing loss.
• CI use enhances auditory perception, positively impacting linguistic processes and communication skills.

Purpose of the Study:

• To evaluate the expressive and receptive oral language performance of children using cochlear implants.
• To identify factors influencing language development in pediatric CI users.

Main Methods:

• Prospective cross-sectional study involving 30 children (36-72 months) with severe/profound bilateral sensorineural hearing loss.
• Utilized child language tests (phonology, vocabulary, fluency, pragmatics) and the Peabody Picture Vocabulary Test.
• Participants had unilateral CI use for at least 12 months with no other impairments.

Main Results:

• Longer CI duration, younger age at implantation, and superior auditory speech perception positively influenced oral language outcomes.
• Children's linguistic skills were below age norms but showed developmental progress.
• Language development in CI users is a key outcome to consider.

Conclusions:

• Extended cochlear implant use, early implantation, and better speech auditory perception are crucial for developing expressive and receptive oral language skills.
• These factors impact various semantic categories, though not universally.
• Focus on developmental progress in pediatric CI users is essential.
