BACKGROUND AND OBJECTIVES: There are some difficulties and dilemmas in treating patients who show acute recurrent infection or persistent inflammation after sinus surgery. Recently, nebulized antibiotic therapy was recommended as another treatment option for these patients. Our study was to evaluate the effect of nebulized antibiotic therapy in these patients. SUBJECTS AND METHOD: We selected 38 adult patients who had received endoscopic surgery previously. They were patients of the refractory group who have showed persistent purulent rhinorrhea despite treatment for 2 months after sinus surgery and the acute exacerbation group who have showed repeated worsening of their symptoms more than 3 times for 6 months. Cultures were taken from all cases and proper oral antibiotics were used based on their culture results. Oral antibiotics were stopped during the nebulized antimicrobial therapy. Nebulized antibiotics therapy was performed 5 times a week for 4 weeks with cefmenoxime hydrochloride using ultrasonic nebulizer. The symptom score and endoscopic appearance were checked also before and 1, 2 and 3 months after the treatment. RESULTS: In 38 patients, 6 patients were excluded due to follow up loss or voluntary stop of treatment and 32 patients were available. S. aureus, P. aeruginosa and coagulase-negative Staphylococcus were most common organisms in all patients. The symptom score and endoscopic appearance after the treatment showed significant improvement. No complication was found in all cases. CONCLUSION: Nebulized antibiotic therapy might be considered as another therapeutic option for patients with refractory or acute exacerbation of chronic rhinosinusitis after endoscopic sinus surgery.
