Long-term Implant Usage and Quality-of-Life in Sequential Bilateral Pediatric Cochlear Implantation

OBJECTIVES Our primary objective was to investigate the long-term usage of cochlear implants (CIs) in children who underwent sequential bilateral CI (SeqBCI), and to study factors that impact usage. Our secondary objective was to understand the difference in subjective benefit and educational/employment status, between users and non-users of the second CI (CI2). STUDY DESIGN Prospective case series. SETTING Tertiary academic centers. PATIENTS Sixty-eight young adults who underwent SeqBCI as children. INTERVENTIONS Pediatric SeqBCI. MAIN OUTCOME MEASURES The main outcome measures were the current usage of the first CI (CI1) and CI2, factors that determine usage, current perceptions of their CIs, educational/employment status, and Speech, Spatial and Qualities of Hearing scale (SSQ12) scores. RESULTS Sixty five (95.6%) participants were using CI1 for over 8 h/d and the rest were using CI1 for 4 to 8 h/d. Fourty four (64.7%) participants used CI2 for at least 4 h/d, 10 (15%) indicated that they rarely used CI2 (
