Laser surgery treats laryngeal and tracheal growths less invasively

Facebook X LinkedIn Email
According to the National Institutes of Health, about 7.5 million people in the US have voice problems. Laryngeal and tracheal growths — a major cause of voice disorders — traditionally are removed surgically under general anesthesia. These growths have a tendency to reappear and often require multiple surgeries. They also can cost patients a few days of recovery time. Dr. Jamie A. Koufman, director of the Voice Institute of New York in New York City, and her colleagues evaluated the use of unsedated office-based laser surgery with three lasers to see how well the minimally invasive...Read full article

    laser surgery
    Laser surgery refers to a medical procedure in which a laser, or focused beam of light, is used as a precision tool to cut, vaporize, coagulate, or otherwise modify tissues for therapeutic or surgical purposes. Lasers offer several advantages in surgery, including precision, minimal invasiveness, and the ability to target specific tissues without causing extensive damage to surrounding areas. The process of laser surgery involves the following key components: Generation of laser light:...
    pulsed-dye laser
    A laser with a gain medium consisting of an organic dye, which is carbon-based. The dye is mixed with a solvent, allowing the molecules to diffuse evenly throughout the liquid. The dye medium is capable of producing a larger range of wavelengths compared to gain mediums composed of gas. Thus, dye lasers are commonly used to obtain high bandwidth in tunable/pulsed lasers.
