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.
钇铝石榴石激光在体外切割人声带时所造成的相对热损伤。结果显示，使用铒：钇铝石榴石激光时完全消除了炭化现象。切口附近凝固性坏死的深度，使用二氧化碳激光时为510微米（±75），而使用铒：钇铝石榴石激光时降至23微米（±12）；在切口底部，使用二氧化碳激光时为125微米（±45），使用铒：钇铝石榴石激光时降至12微米（±8）。文中还讨论了喉手术后在术后愈合方面的潜在优势。
