An in vitro comparison of the Erbium: YAG laser and the carbon dioxide laser in laryngeal surgery.
This study compares the relative thermal damage caused by a surgical CO2 laser and the Erbium:YAG laser when used to incise the human vocal fold in vitro. Results show that charring is completely eliminated when using the Erbium:YAG laser. The depth of coagulative necrosis adjacent to an incision is reduced from 510 microns (+/- 75) using the CO2 laser to 23 microns (+/- 12) using the Ebrium:YAG laser and at the base is reduced from 125 microns (+/- 45) using the CO2 laser to 12 microns (+/- 8) using the Erbium:YAG laser. The potential advantages regarding post-operative healing after laryngeal surgery are discussed.
