[Surgical management of inflammatory disease in the frontal and ethmoid sinuses (author's transl)].

The opening microscope became very important in nasal sinus surgery, especially for operating procedures of the ethmoid sinus. For many authors nasal polyposis without putrid secretion is an indication not only for polypectomy, but for ethmoidectomy. Using the operating mikroscope frontal sinus surgery can be performed in a much more delicate way. The best cosmetic results are seen after osteoplastic opening of the frontal sinus. This technique can not be used if ostitis or osteomyelitis is present. There are several ways to treat mucosal changes in the frontal sinus. Its lumen may be drained as soon as there are no severe mucosal changes. In severe cases the mucosa must be removed and the sinus lumen should obliterate either spontaneously or after implantation of autologous material. - Endonasal surgery of the frontal and ethmoid sinus can be hazardous in unexperienced hands.
