비중격 성형술과 내시경 부비동 수술시 비강 세균 및 균혈증에 대한 연구

Background and Objectives: Septoplasty and endoscopic sinus surgery are common intranasal operations. Infectious complications of nasal packing after rhinologic surgeries have been reported. In this study, we compared the preoperative bacterial distribution of nasal cavity to the postoperative bacterial distribution cultured from nasal packings and investigated if the bacteremia during the operations were developed. Materials and Methods: This study included 30 septoplasty and 30 endoscopic sinus surgery patients. Nasal culture was taken preoperatively. And then postoperative culture from the nasal packing was done. Blood cultures were obtained before mucosal incision during operation, at the postoperative 2nd day (maintaining nasal packing), 3rd day (after removal of nasal packing). Results: Significant bacterial growth was detected from preoperative nasal culture in 40.0% of septoplasty group and 70.0% of endoscopic sinus surgery group, each. Staphylococcus aureus was detected in 13.3% of septoplasty group, 23.3% of endoscopic sinus surgery group. The detection ratio of bacteria was higher in endoscopic sinus surgery group. In the result of postoperative culture from nasal packings, bacterial growth ratio was 36.7% in septoplasty, 50.0% in endoscopic sinus surgery group. In case of Staphylococcus aureus, 10.0% and 20.0%, each. Bacterial growth from blood cultures detected in only 2 cases of septoplasty group. But bacteria were detected in different two patients. It is supposed to be contaminated. No bacterial growth was detected in endoscopic sinus surgery group. Conclusion: It is supposed that postoperative intravenous antibiotics prevent bacterial growth of nasal packing and bacteremia. (J Clinical Otolaryngol 2007;18:212–218)
