In Vitro Comparison

AbstractThis 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 ±m(µ 75) using the CO2 laser to 23 ±m(µ 12) using the Ebrium: YAG laser and at the base is reduced from 125 ±m (µ 45) using the CO2 laser to 12 ±m (µ 8 ) using the Erbium: YAG laser. The potential advantages regarding post-operative healing after laryngeal surgery are discussed.

Smoke Evacuation

A laryngoscope has been developed for microlaryngeal laser surgery in the posterior commissure of the larynx. The tip has been designed to facilitate exposure of one entire arytenoid and the posterior commissure. Other features include a concavity on the superior lip of the tip to hold the endotracheal tube anteriorly, a bifurcated smoke evacuation channel and a nonreflective finish. It is anticipated that this laryngoscope will be available in pediatric and adolescent sizes in addition to the adult size that we have worked with.

Laser Effect

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.
