title: Prospective randomized investigation for evaluation of postoperative changes in the microbial climate of paranasal mucosa by the use of different dissoluting techniques during postoperative care.
abstract: Endonasal dissolution by the use of NaCl-solution is a common postoperative treatment of the nasal mucosa after endonasal surgery. These procedure involve for example endonasal shower and sterilized solutions. The contamination of nasal shower in case of unprofessional cleaning after treatment was an argument against this technique in earlier discussions. The danger of such an infection should be avoided by the use of sterilized solution. Therefore the dependence of nasal microbial climate on different nasal dissoluting techniques was investigated by the use of such named endonasal shower (Siemens und Co, Bad Ems, Germany) in comparison with sterilized solution (Rhinomer, Zyma SA, Nyon, France). Microbial cultures were investigated of 80 patients after endonasal surgery (53 m, 27 f; 31 +/- 21 age). Surgery was done for the treatment of chronic polypous sinusitis. Pre-, intra- and postoperative samples were taken in 640 cases to proceed microbial cultures. Material was transferred with the use of a Port-A-Cul-transport medium and preparation of the microbial cultures was done during the first four hours. As a result 895 bacterial clones were cultivated. These consisted of 87% aerob and 13% anaerob bacteria. Staphylococcus aureus (39%) and members of the family of Enterobactericae (30%) were the most common microbes. There was neither an evidence for postoperative microbes on the nasal mucosa nor a correlation between the dissoluting technique and the postoperative outcome. The use of sterilized solutions for the postoperative care of endonasal mucosa does not cause an additional worthful effect on neither the postoperative microbial climate nor the outcome in comparison to endonasal shower.
