    Insights

    Auditory Brainstem Implants (ABI) show promising results for pediatric hearing rehabilitation in Hong Kong. Continued ABI use improves speech development in children with profound prelingual deafness.

    Area of Science:

    • Otolaryngology
    • Pediatric Audiology
    • Neuroscience

    Background:

    • Profound prelingual deafness presents significant challenges for pediatric audiological rehabilitation and language development.
    • Auditory Brainstem Implants (ABI) offer an alternative for patients with cochlear nerve deficiency or malformations unsuitable for cochlear implants.

    Purpose of the Study:

    • To evaluate the impact of Auditory Brainstem Implants (ABI) on audiological rehabilitation and tonal language development.
    • To assess speech development outcomes in pediatric patients with profound prelingual deafness rehabilitated with ABI in Hong Kong.

    Main Methods:

    • Retrospective review of 11 pediatric patients (age 1.67-3.75 years) who received ABI between 2009 and 2015.
    • Utilized standard pediatric cochlear implant outcome measurements, including sound detection, syllable/vowel/consonant identification, and tone production/imitation.
    • Compared outcomes with age-matched pediatric cochlear implant users, focusing on Cantonese language rehabilitation.

    Main Results:

    • Encouraging speech development outcomes were observed, particularly with sustained ABI use.
    • Significant variability in outcomes was noted, with poorer performance in children with coexisting cognitive disabilities.
    • Audiological rehabilitation and speech perception showed improvement over time.

    Conclusions:

    • Auditory Brainstem Implantation (ABI) is a safe and effective treatment option for pediatric profound prelingual deafness.
    • ABI facilitates audiological rehabilitation and speech development in Cantonese-speaking children.
    • Individual patient factors, including cognitive abilities, influence ABI outcomes.

    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...

    Brainstem

    The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
    The Midbrain
    The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

    Language

    Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
    Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

    Components of Language01:24

    Components of Language

    Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

    Language and Cognition01:27

    Language and Cognition

    Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

    The Auditory Ossicles01:11

    The Auditory Ossicles

    The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
    The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
