Comparative Studies Between CO₂ Gas Laser and YAG Laser on the Tracheal Cilia

Abstract

We investigated effects of laser beam surgery on the bronchial cilia using CO₂ gas laser and YAG laser.
Scanning electron microscopic observation reveled that the YAG laser had a stronger effect to the surrounding tissues. YAG laser can be expected more dehydration of the tissue fissure and tear of the tissue. YAG laser is also significant for the promotion of the coagulation of the tissue.
