[Endoprosthesis of the frontonasal anastomosis after extranasal radical operations using biocompatible tubular...

The authors present pilot experience of extranasal radical operations on the frontal sinuses with the use of polymeric tube endoprostheses made of biocompatible polymeric materials EFOS 1, 2, 3 containing antimicrobial drugs (dioxidin, chinoxidin) and active substances promoting regeneration and epithelization (orotic acid derivatives). The above technique was employed in operations on frontal sinuses in 12 patients. Polymeric endoprostheses EFOS provide adequate lumen of the formed frontonasal anastomosis, reduce the occurrence of postoperative complications and recurrences as well as hospital stay.
