Blue laser as a safe option in laser airway surgery

Abstract

Shortly after Theodore Mainman invented the ruby laser in 1960, it was quickly adopted by otolaryngologists to remove cancerous lesions with precision. Early lasers, however, caused significant tissue damage, and finding the right wavelength for effective tissue absorption was challenging. Patel’s invention of the carbon dioxide laser was a breakthrough due to its 10,600 nm wavelength, which is easily absorbed by water in tissues. This laser became popular I surgery for its continuous wave, high-output power, and precise focus. By the 1980s, various specialized lasers with specific benefits and drawbacks had been developed. A know risk with laser surgery, especially in the airway, is operating room and airway fires.
