Objective: The purpose of this study is to retrospectively review the complications of cochlear implantation in pediatric patients. Materials and Methods: The study included 344 pediatric patients (younger than 18 years of age) who had undergone cochlear implantation surgery between September 2005 and May 2010. The patients were regularly monitored, with a mean follow-up period of 31 months (ranging from 9 to 66 months). All of the operations were performed by the same surgeon (YG). Results: 13 major (3.8%) and 12 minor (3.5%) complications were observed. Major complications included local flap failure (3 patients), soft device failure (2 patients), magnet displacement following head trauma ( 2 patients), electrode displacement to vestibule (1 patient), reference electrode migration to dura mater with facial paralysis (1 patient), electrode extrusion from the external ear canal (1 patient), hard device failure after trauma (1 patient), electrode breaking into the mastoid cavity (1 patient) and bleeding from the sigmoid sinus during the operation (1 patient). The implants were removed from 8 of the patients (2.3%) and re-implanted in all of them (2.3%). Minor complications included vestibular symptoms (4 patients), seroma formation (3 patients), recurrent acute otitis media(3 patients), hematoma following head trauma (1 patient), and seizure (1 patient). Conclusion: Power of the study is that all the operations were performed by a single surgeon and sample patients group was homogenous. When compared with the other methods reported, 3.8% major and 3.49% minor complication rates were lower than expected. These complications should be kept in mind during the Cl surgery and the surgeon should be work to avoid them and be familiar with them enough to treat them.
