[Rhinosinusitis. Current diagnostic and therapeutic aspects].

Over the past years, the incidence of acute and chronic forms of rhinosinusitis has been increasing, and between 10 and 15% of the population of Central Europe are affected annually. Accordingly, the economic significance of rhinosinusitis is considerable. This makes the need for appropriate diagnostic and therapeutic strategies all the more urgent. In addition to case history and a physical examination, a helpful diagnostic strategy also includes rhinoendoscopy and--in particular in preparation for surgery--a CT scan. A plain radiograph does not suffice to confirm chronic sinusitis. The major therapeutic pillar in the treatment of acute rhinosinusitis is medication in conformity with accepted guidelines (proof of efficacy!). In the majority of cases chronic courses can be managed by minimally invasive surgery.
