Recalcitrant Rhinosinusitis, the diagnosis and treatment and evaluation of results

Chronic Rhinosinusitis can be a debilitating disease. Since ancient times people are aware of this disease and potential treatments. In most patients rinsing with NaCl, and medical treatment, like local corticosteroids and if necessary (long term) antibiotics is an effective treatment. In a subpopulation this medical treatment is insufficient and FESS is necessary. In most studies FESS has been reported to be effective in over 80% of the cases. However in a small group of patients even the combination of medical and surgical treatment fails, the disease of these patients is often termed recalcitrant rhinosinusitis
