Efficacy of auditory verbal therapy in children with cochlear implantation based on auditory performance – A systematic review

Abstract

This systematic review focuses on the efficacy of auditory verbal therapy (AVT) in children with cochlear implants based on their auditory performance. The results presented are based on research findings from 2010 to 2021. The systematic review was designed based on the Popular Reporting Systems for the Systematic Review and Analysis of Meta-Analysts (PRISMA), the 2020 revised version, and the Critical Evidence for Clinical Evidence (CATE) checklist. Specific keywords were chosen based on the formulated research question and searched on the following search engines: Google Scholar, Microsoft Academic, PubMed, Semantic Scholar, Cochrane, Science Direct, and BASE. All the searched articles were analysed based on specific exclusion criteria. The results revealed an important progression based on the auditory performance among children with cochlear implantation who received habilitation. The studies highlight that younger the age at implantation better the auditory performance and this may be necessary to allow at least relatively normal organization of auditory pathways in pre-lingual children with hearing impairment. Therefore, regular revitalization of aural–verbal rehabilitation and speech and language therapy is essential for younger children with hearing impairment to achieve the highest level of hearing function. This systematic review highlights importance of assessment of the auditory performance to be considered in the test battery while evaluating children with CI before and after habilitation along with AVT.
