Unexpected findings and surgical complications in 505 consecutive cochlear implantations: a proposal for reporting consensus

Cochlear implantation is a safe procedure in experienced hands, as the rate of severe complications is below 2%. Complications differ between children and adults, and transient disequilibrium/vertigo is the most common complication, followed by wound infection, haematoma/oedema and transient chorda tympani syndrome. An international consensus on the reporting of complications is proposed, as a high degree of variability occurs in the literature, which precludes an overview necessary for adequate patient information and for incentives aimed at prevention.
