Mechanism study of nodules in the vocal cords treated by a He-He laser

摘要

Abstract: Five hundred and fifty-one cases of nodules in the vocal cords were treated by a He-He laser. To study the cure mechanism following experiments that were the examination of immune function the test temperature, the examination with indirect laryngoscope, the study of microstructure in the larynx, the test attenuated bacteria, and examination of the lipid peroxide were performed. It was demonstrated that the mechanism was able to make the temperature of the larynx rise, the blood vessel expansive, and hemocirculation rapid so as to increase local nutrition and immune function, accelerate the membranous growth in the larynx, eliminate edema in tissue, and make excretion of inflammatory effusion and poison rapid. The treatment spanned the years 1980 to 1992, the therapeutic effect was good. Study of the cure mechanism following the experiment was performed. !0
