A common practice in the management of patients with chronic rhinosinusitis (CRS), the empirical use of antibiotics may contribute to treatment failure and to the development of antimicrobial resistance.
This was a prospective cross-sectional study in which endoscopically guided middlemeatal swabs (IBMSpss, version 16.0, Chicago, IL, USA) were aseptically taken from patients diagnosed with CRS after obtaining informed consent and ethical clearance. The samples were sent to the laboratory for qualitative and semiquantitative analysis via gram stain, aerobic, anaerobic cultures and antibacterial sensitivity tests. The collected data was analyzed using SPSS for Windows, version 16 (SPSS Inc, Chicago, IL, USA). Simple statistical parameters and paired sample t-test were used, as appropriate.
