摘要

To analyze the incidence, spectrum, timing, and management of post-operative complications in a large pediatric cochlear implantation cohort over a ten-year period at a single tertiary center. We conducted a retrospective cohort study of all children (≤ 18 years) who underwent primary cochlear implantation between January 2015 and April 2025. Complications were classified as early (≤ 30 days) or late (> 30 days) and categorized as infection, skin-related, device failure, trauma, or electrode misplacement. Data were analyzed using descriptive statistics, and management strategies were summarized. Of 507 assessed, A total of 493 children were included, 462/493 (93.7%) had ≥ 12 months follow-up. Twenty-one complications occurred (4.3%; 21/493), with late events predominant (14/21; 66.7%). Device failure most common (7/493; 1.4%), followed by infection (4/493; 0.8%), trauma (4/493; 0.8%), skin extrusion (3/493; 0.6%), electrode misplacement (3/493; 0.6%). Re-implantation rate 1.4% (7/493). This large, single-center series confirms the high safety profile of pediatric cochlear implantation. The complication rate is low, and events are manageable with standardized protocols. Vigilant long-term surveillance, structured device failure diagnostics, and continuous surgical technique refinement are paramount to minimizing morbidity and ensuring optimal patient outcomes.
