Background Acute rhinosinusitis is an acute infection of the nasal passages and paranasal sinuses that lasts less than four weeks. Diagnosis of acute rhinosinusitis is generally based on clinical signs and symptoms in ambulatory care settings. Technical investigations are not routinely performed, nor are they recommended in most countries. Some trials show a trend in favour of antibiotics, but the balance of benefit versus harm is unclear. We merged two Cochrane Reviews for this update, which comprised di erent approaches with overlapping populations, resulting in di erent conclusions. For this review update, we maintained the distinction between populations diagnosed by clinical signs and symptoms, or imaging. Objectives To assess the e ects of antibiotics versus placebo or no treatment in adults with acute rhinosinusitis in ambulatory care settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
