PURPOSE OF REVIEW: Sinusitis is a leading reason for outpatient antibiotic use, but symptoms are nonspecific. We review potential methods that might enhance the ability to appropriately prescribe antibiotics. RECENT FINDINGS: The evidence base for antibiotic use in acute rhinosinusitis is strongest in studies with stringent entry criteria. In less restrictive studies antibiotics and placebo perform equally. Bacteria from nasopharyngeal swabs in adults correlate with sinus cultures. A recent study showed that antibiotics shortened the duration of acute rhinosinusitis (ARS) symptoms in children. Tellingly, over 2000 children with symptoms were screened to enroll less than 10% who fulfilled the study's stringent criteria. In chronic rhinosinusitis (CRS), two grade 1 studies on efficacy of long-term macrolide therapy showed conflicting results. Odontogenic sinusitis is underappreciated and frequently fails to grow on culture because of presumed difficulty in growing anaerobes. SUMMARY: There is currently no grade 1 evidence to support antibiotic use in CRS; however, studies to date have not been conducted in patients with isolated purulent sinusitis. Future use of cultures to direct antibiotic therapy, such as nasopharyngeal swabs in adults with ARS or endoscopically guided cultures, may aid in targeting antibiotic therapy more effectively.
