Laser surgery is a type of surgery that uses light beams instead of standard surgical instruments. The laser beam hits tissue, and some light is reflected, but the remaining light is absorbed through the tissue. The absorbed light has specific effects, providing the desired treatment. There are many advantages of laser surgery, especially with endoscopic procedures where surgeons have limited access to confined areas. The lasers can be very precise and limit blood loss. Conditions commonly treated with laser surgery include vascular lesions and upper and middle airway disorders.
