Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Language Development

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Summary

Cochlear implantation in children under two years old is safe and effective, leading to comparable speech perception outcomes to older children. Early implantation supports better language and speech development in prelingually deafened children.

Area of Science:

Otolaryngology
Pediatric Audiology
Speech-Language Pathology

Background:

Cochlear implantation provides hearing benefits but is controversial for prelingually deaf children due to diagnostic, safety, and management concerns.
Implantation in children under 2 years may pose higher surgical risks and management challenges.

Purpose of the Study:

To evaluate the safety and efficacy of cochlear implantation in children under 2 years old.
To compare speech perception outcomes in early-implanted children with those implanted at older ages.

Main Methods:

Review of surgical series and outcomes in children under 2 years old at the time of cochlear implantation.
Assessment of auditory behaviors using tools like the Listening Progress Profile and Categories of Auditory Performance.

Main Results:

Satisfactory perioperative and postoperative surgical outcomes were observed in children implanted under age 2.
Significant improvements in auditory performance were noted, with no significant differences compared to a control group implanted at ages 3-5.
Parental observations indicate early-implanted children perform as well as later-implanted peers.

Conclusions:

Cochlear implantation can be performed safely in children under 2 years old.
Early cochlear implantation yields speech perception results comparable to later implantation.
Early implantation facilitates improved speech reception, language acquisition, and reading comprehension in prelingually deaf children.
