[Sarcoidosis of the paranasal sinuses]

The authors described diagnostics difficulties, clinical features and treatment of this disease. The treatment is insufficient, but only interventional, although the clinically dominating symptoms may be due to a chronic disease inside of the sinuses and they are known to be caused by specific disorders in immunology. Immunosuppression, using prednisone, and reestablishing sinus ventilation and drainage via natural ostia is the basis of treatment, but it does not lead to recovery. Two rare cases of paranasal sinuses sarcoidosis are described.
