AbstractObjective: This is a retrospective review of the impact of an Auditory Brainstem Implant (ABI) on the audiological rehabilitation and tonal language development of pediatric patients with prelingual profound deafness in Hong Kong.
Results: From January 2009 to September 2022, 23 pediatric patients with profound prelingual deafness received an ABI in Hong Kong (age range 1;07–5;00 years). Etiologies included Cochlear Nerve Deficiency, Severe Cochlear Malformations, and Retrocochlear Deafness. Pediatric outcome measurements were used in this study including Speech Perception Category, Meaningful Auditory Integration Scale (MAIS), Cantonese Tone Identification Test (CANTIT), Cantonese Spoken Word Recognition Test (CANSWORT), speech intelligibility rating and speech reception ability rating.
Conclusion: Encouraging results of speech development were found, especially with continued use of the
ABI. There was considerable variation in outcomes. Children with coexisting developmental and nonauditory cognitive disabilities did not perform as well. Auditory brainstem implantation is a safe and beneficial treatment for profound prelingual deafness in Cantonese-speaking pediatric patients. Findings from this study are highly comparable to other published case series from established ABI centres around the world.
