Description
Summary:Introduction: The aim of this study was to report the frequency and management of postoperative wound infections and to investigate bacteriology and biofilm formation following 653 consecutive cochlear implantations in adults. Methods: A retrospective file review of 653 consecutive adult cochlear implantations between 1994 and 2015 at the Department of Otorhinolaryngology at Odense University Hospital. A reporting consensus was used to classify infections. Results: The major and minor infection rates were 2% and 8%, respectively. The explantation rate due to infection was 1%. The most common pathogen found was Staphylococcus aureus and biofilm formation was found in 73% of the explantations. Conclusion: Postoperative infection occurred in 10% of the implantations. However, few of these were severe. Staphylococcus aureus was the most common pathogen and the presence of biofilm seemed to be associated with a higher risk of explantation.
