Nd:YAG Laser Surgery: Overview of Applications
Since its introduction into clinical medicine the neodymium:yttrium aluminum garnet (Nd:YAG) laser has found definite multispecialty use. The carbon dioxide (CO2) laser is clearly established as the premier precision cutting device but is seriously lacking in endoscopic applications because of its inability to be transmitted through available fibers. Certain specialties, such as otolaryngology, gynecology, and neurosurgery, still use the CO2 laser in preference to other laser wavelengths, since accessibility to the larynx, cervix, and brain is adequate without fiber technology. Good hemostasis with the CO2 laser, primarily for capillary-size blood vessels (microvasculature), and the ability to predict its precise soft tissue interaction have made it ideal for such applications as excisional biopsy of early carcinoma of the vocal cord and control of carcinoma in situ of the cervix. However, treatment of malignancy originating in such vascular areas as the trachea or bronchus requires more reliable hemostasis. For control of blood vessels larger than capillary size the Nd:YAG laser is the ideal wavelength.
