• Cochlear implants (CI) have enabled an increasing proportion of deaf children to develop oral communication. Despite the well-known benefits of bilateral implantation, many of these children and teenagers have only a unilateral implant. The aim of this study was to evaluate the benefits of sequential bilateral CI and the influence of relevant factors on outcome. A single-center retrospective study included 109 children and adolescents who received a second sequential CI between 2008 and 2016. Subjects were evaluated before sequential implantation and subsequently at 3, 12 and 24 months, on Speech Intelligibility Rating and speech perception tests: Categories of Auditory Performance, word and sentence recognition in silence and in noise. The influence of inter-implant interval and performance with the first CI were analyzed. In the majority of patients, sequential CI provided significant improvement in speech and intelligibility perception. These benefits were seen not only for short but also for long inter-implant intervals. Some subjects with poor performance with their first implant showed significant progression after sequential bilateral implantation. In view of the benefits of sequential bilateral CI, we suggest that a second CI should be proposed to all unilaterally implanted children and adolescents, regardless of inter-implant interval and initial performance with the first CI. Further studies need to be conducted to identify prognostic factors for success in sequential contralateral implantation.
