Bacterial Infection After Endoscopic Sinus Surgery: A Controlled Prospective Study

Abstract

Although the postoperative sinonasal cavity may be colonized by bacteria after endoscopic sinus surgery, infections arising postoperatively most commonly represent de novo infections by bacteria other than colonizing bacteria. Empirical therapy based on baseline data may be misleading; acute exacerbations of chronic rhinosinusitis after endoscopic sinus surgery should be cultured to guide optimal antibiotic therapy.
