[Reestablishing of nasal respiration with Holmium laser in distortion of nasal septum in cartilaginous part].

To study mechanisms of cartilage modelling, estimation of optimal parameters and regimens of laser radiation, the authors made in vitro and human experiments on nasal septum cartilages and in vivo experiments on cartilages of the floor of the auricle in rabbits and pig. Ho-laser radiation is thought the most appropriate tool for cartilage shaping. A method of non-invasive correction of the nasal septum cartilage in its distortion has been designed. 2/3 of the patients recovered or improved nasal respiration. Laser operation has no age restrictions, is non-invasive, can be made outpatiently, is not followed by pharmacological treatment.
