Sinusitis is inflammation of the sinuses often resulting from catarrhea in combination with an infection or a flu, in which the mucosa is predominantly affected, and less often the underlying bone tissue. Initially, a mucus or mucus-secretion is released. The pain of the affected area is characteristic – in the area of the forehead or the maxillary area. Headaches and high temperature cleansing always accompany the disease. An X-ray image shows shadowing in the sinuses. Chronic sinusitis is most commonly due to unstressed acute sinusitis. The complaints are the same, but more overwhelmed – the pungent stuff secrets with unpleasant smell. The task of physiotherapy is to prevent inflammation and pain and swelling of mucous membranes. A very good result is the laserpuncture combined with others.
