Lasers In Head And Neck Surgery

The correct answer is "Light Amplification by Stimulated Emission of Radiation". This is the correct acronym for LASER.

The carbon dioxide laser is the most commonly used laser in surgery because it can be used for a wide range of surgical procedures. It emits a wavelength of light that is easily absorbed by water, making it effective for cutting and vaporizing tissues. The carbon dioxide laser is also known for its precision and minimal damage to surrounding tissues, making it a preferred choice for delicate surgeries.

The patent war lasted for three decades. This suggests that it was a long and protracted conflict that spanned over a period of thirty years. The length of the war indicates that it was a complex and contentious issue that required a significant amount of time to resolve.

Laryngotracheal reflux is not treated using lasers in laryngology. This condition involves the backflow of stomach acid and other stomach contents into the larynx and trachea, causing irritation and inflammation. Treatment for laryngotracheal reflux typically involves lifestyle changes, medication, and sometimes surgery, but not the use of lasers. Lasers may be used in laryngology for other conditions such as cysts, cutting the vocal cord, nodules, and cancer.

Adding different chemicals can change the type of laser because the chemicals used in the laser medium determine the wavelength and characteristics of the laser beam. The interaction between the electrons in the atoms or molecules of the chemicals and the energy source stimulates the emission of light, resulting in a specific type of laser. By adding different chemicals, the composition of the laser medium is altered, leading to a change in the type of laser produced.

The correct answer is Excimer Laser. The Excimer Laser is specifically designed for LASIK eye surgery. It emits ultraviolet light, which is used to reshape the cornea and correct vision problems. This type of laser is preferred for LASIK surgery because it is highly precise and can remove tissue without generating heat, reducing the risk of damage to the surrounding eye tissue.

The Ho:YAG laser is the best laser for dissolving stones. This laser emits a wavelength of light that is specifically absorbed by water, making it highly effective for breaking down stones that are composed of calcium oxalate or calcium phosphate. The laser energy is absorbed by the water in the stone, causing it to heat up and break apart. The Ho:YAG laser is also able to penetrate deeper into tissues, making it a preferred choice for treating larger stones.

Gordon Gould is credited with inventing the laser. Although Albert Einstein laid the theoretical groundwork for the laser in the early 20th century, it was Gould who obtained the first patent for a laser device in 1959. Gould's invention was based on the concept of stimulated emission of radiation, which he developed while working on his doctoral thesis. His invention paved the way for the practical application of lasers in various fields, including medicine, telecommunications, and industry.

The given answer, Excimer Laser, is the correct answer because it is one of the types of lasers mentioned in the options. The question asks for the kind of laser, and Excimer Laser is a specific type of laser that uses a combination of noble gases and halogens to produce short-wavelength ultraviolet light.

The given list consists of various components or parts related to a certain device or system. The missing part is "Beam Chamber" as it is the only component that has not been named in the list.
