Application of polymeric endoprostheses in surgery of external ear

Biocompatible polymeric endoprostheses EFOS are offered for endoprosthetic reconstruction of the external acoustic meatus in atresia. Such endoprostheses are safe for the adjacent tissues. Moreover, such prostheses contain antibacterial drugs (quinoxidine, dioxidin) and substances promoting tissue regeneration (orotic acid derivatives). This provides good epithelization of the walls of the newly established external acoustic meatus and sufficient lumen of the organ. The removal of the endoprosthesis is recommended on the postoperative day 90-120 in the outpatient setting.
