High demands on freedom from germs are made on auditory ossicles to be used as implants. Postoperative infections often result from the existence of germ-contaminated ossicles. That is why we undertook microbiological examinations, using three frequently applied preserving methods for auditory ossicles kept for tympanoplasties. The results of the examinations were: Disinfection by Cialit (often used in clinical practice) produced unsatisfactory results. Disinfection by ethyl alcohol (70 per cent) and a subsequent treatment with thiomersal-Ringer's solution (0.4 per cent) yielded satisfactory results. Disinfection by preservation with an aqueous solution of formalin and subsequent treatment with Cialit proved most effective. None of the applicated germs could be regrown.
用作植入物的听小骨对无菌要求很高。术后感染常常是由于存在被细菌污染的听小骨所致。这就是为什么我们采用三种常用的保存方法对用于鼓室成形术的听小骨进行保存，并进行了微生物学检查。检查结果如下：临床实践中常用的西阿利特消毒效果不理想。用70%乙醇消毒，随后用0.4%硫柳汞林格氏液处理，效果令人满意。用福尔马林水溶液保存并随后用西阿利特处理的消毒方法最为有效。所应用的细菌均无法再生长。
