Abstract

Early activation of Cochlear Implant (CI) is a technique where the processor is activated in less than 4 weeks. In this way, time and costs are reduced in the process of functional restoration of hearing. On the other hand, a late sequential cochlear implant is one where the second CI is implanted at a different surgical time than the first and the user’s age is greater than 7 years. The aim of systematic review is to analyze the available information on the effects of early activation after late sequential cochlear implant surgery. Systematic literature search was performed, in databases, of studies about the effects of early activation of late sequential CI and early activation of CI in terms of quality of life, hearing and language from the years 2012 to June 2022. Fifteen publications were included in the clinical evidence review for early CI activation review, but no articles were found for review on the topic of early activation of late sequential CI. The review identified early CI activation as a safe and reliable procedure where the effects are positive on quality of life, hearing and speech by electrophysiological and auditory perceptual recordings. However, no information about the effects on early activation of late sequential CI is recognized.
