Summary
Persistent rhinosinusitis after endoscopic sinus surgery (ESS) is often caused by bacterial infections. Postoperative cultures reveal increased Gram-negative rods and antibiotic-resistant organisms, necessitating targeted treatment strategies.
Area of Science:
- Otolaryngology
- Microbiology
- Infectious Diseases
Context:
- Chronic rhinosinusitis (CRS) affects millions globally.
- Endoscopic sinus surgery (ESS) is a common treatment for CRS.
- Persistent or recurrent infections post-ESS pose a clinical challenge.
Purpose:
- To investigate the microbiological differences in persistent rhinosinusitis following ESS.
- To compare bacterial profiles in preoperative and postoperative sinus cultures.
- To identify pathogens contributing to treatment failure after ESS.
Summary:
- 143 patients with CRS undergoing ESS were studied.
- Preoperative and postoperative (if persistent) ethmoid sinus cultures were analyzed.
- Postoperative cultures showed a higher prevalence of Gram-negative rods and antibiotic-resistant organisms compared to preoperative cultures, while anaerobes decreased. Gram-positive cocci remained predominant.
Impact:
- Highlights bacterial infection as a key factor in persistent rhinosinusitis post-ESS.
- Suggests a shift in microbial landscape after surgery, with an increase in Gram-negative rods and resistance.
- Emphasizes the importance of obtaining postoperative sinus cultures for guiding targeted antibiotic therapy in persistent cases.
