Abstract
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.

简介:这项研究的目的是报告术后伤口感染的频率和处理, 并调查653次成人人工耳蜗植入后的细菌学和生物膜形成。
方法:回顾性分析1994年至2015年在欧登塞大学医院耳鼻咽喉科进行的653例连续成人人工耳蜗植入。 一份报告协同用于对感染进行分类。
结果:主要和次要感染率分别为2%和8%。 因感染而导致的外植率为1%。 所发现的最常见的病原体是金黄色葡萄球菌, 并且在73%的外植体中发现了生物膜的形成。
结论:术后感染发生率为10%。 但是, 其中很少是严重的。 金黄色葡萄球菌是最常见的病原体, 并且生物膜的存在似乎与较高风险的外植体相关。
