[Morphological changes in the nasal mucosa after diathermo-coagulation in chronic hypertrophic rhinitis].

Morphological changes were investigated in 15 patients suffering from chronic hypertrophic rhinitis after 1, 3, 7, 14, 21, 30, and 120 days of treatment with high frequency current diathermocoagulation of concha nasalis. During treatment an area of coagulation necrosis was formed along the electrode passage which was replaced with sclerotic connective tissue by day 30. The tissue provided a stable reduction of the hypertrophic concha nasalis. The functional activity of its mucous membrane remained unaltered.
