Morphological and Ultrastructural properties of changes caused by use of radiofrequency wave energy - RFTA (500 J, 70°C) in rabbit's lower nasal turbinate mucous membrane was studied. It proved that 7 days later this influence causes morphological and ultrastructural changes in the mucous membrane of the turbinate such as disorders of the epithelium, shortening of cilia and decrease in their number or disappearance, degeneration of microtubular pairs, dinein arms, thickening in basal membrane, irregularity, and subepithelial fibrosis. 8 weeks after influence of radiofrequency wave disorders in epithelium, cilia and basal membrane are diminished, at the same time subepithelial fibrosis remains at the level of the 7th day of the influence. By the time, these changes may be evaluated as indices of continuation of regenerative process in turbinates, decrease in their volume and nasal obstruction.
