Auditory perception and oral language in brainstem auditory implant users: a scoping review

Abstract

Purpose This scope review aims to map current evidence in relation to auditory perception of speech and oral language development in users of Auditory Brainstem Implant - ABI, to answer the following guiding question: “what do we know about the ability of auditory perception of speech and oral language in auditory brainstem implants users?” Research strategy The search was performed in the BVSalud, PubMed and SciELO databases and for gray literature the source of information Google Academic, using the descriptors: auditory brainstem implantation , language, hearing and auditory perception. Selection criteria Studies were included in which tests were applied to assess auditory perception or to verify oral language development in children and/or adults using ABI. Articles published in the last five years were included and secondary studies were excluded. Results 1767 articles were found in the databases and source of information, of which 27 studies were included. It was observed that most users of ABI become able to perceive some environmental sounds, some become able to recognize words, but few reach the recognition of sentences. Conclusion Most ABI users do not advance towards the open set auditory recognition skill and there is unanimity in recommending visual communication methods for these individuals.
