Carbon-dioxide lasers have become useful in surgical procedures because water (which makes up most biological tissue) absorbs this frequency of light very well. Some examples of medical uses are laser surgery and skin resurfacing ("laser facelifts ", which essentially consist of vaporizing the skin to promote collagen formation). [ 9 ]
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
Electrosurgery is an alternate treatment, but local anesthesia is required, making it less practical than cryosurgery. With both techniques, adjacent tissue damage can delay healing and promote scar formation. [11] More extensive or recurring areas of actinic cheilitis may be treated with either a shave vermillionectomy or a carbon dioxide laser.
A fractional laser delivers laser light to the skin. Hundreds or thousands of laser pinpoints may be used per square inch, leaving healthy skin between the ablated areas. Complications observed in a study of 961 treatments included acne and herpes outbreaks. [6] There have been anecdotal negative accounts of bad scarring and hyperpigmentation. [7]
It can be carried out by traditional surgical techniques or, increasingly, by carbon dioxide laser. [3] CO 2 laser cordectomy has allowed the treatment of glottic carcinoma as a day case procedure. [4] The procedure has also been carried out by veterinarians to reduce the volume of incessant barking by dogs, where it is called debarking. [5]
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
