The characteristics of CO2 lasers that render them interesting for surgical applications are reviewed. An instrument consisting of an integrated CO2 laser and beam manipulator, designed specifically for surgical research work, is descirbed. Operational characteristics of the instrument relevant to such work are reported. An accessory for endoscopic surgery is described and instrumentation for microsurgery is discussed. Surgical researches now in progress with this instrument are mentioned.read more

Surgery to Elevate Vocal Pitch
TL;DR: Excessively low vocal pitch found in women is assoicated frequently with the side effects of hormonal drugs, such as anabolic or male hormones, and less frequently with hormonal diseases.

Morphology of Tracheal Scar after Resection with CO2-laser and High-frequency Cutting Loop: A Study in Normal Pigs
TL;DR: Both CO2-laser and ECL caused severe (but not identical) damage to the tissue, clearly visible after 3 months, however, the deformation caused by ECL was not seen at the laser-resected sites, which makes the laser technique seem preferable--where economy permits.

TL;DR: In seven dogs, anesthetized and heparinized, bleeding ulcers caused by hot acid jets stopped after five seconds of laser radiation, and the rapid production of hemostasis leads to consideration of the CO2laser in certain poor-risk patients who have massive bleeding from gastric erosions.
