Laser Surgery: A Practical Guide

Surgeries where light beams are used for different operative procedures by absorbing laser energy and controlling reflection, scatter, and transmission are simply termed laser surgeries. Photobiomodulation (PBM) is extensively known for its therapeutic benefit in the safeguarding and regeneration of tissues by employing visible light to excite biological functions in a non-thermal and non-cytotoxic mode. By using a twenty-watt CO2 laser with a straightened handpiece and a 1.4 mm metal grip, aural hematoma of canines and felines can be easily done. Lateral ear canal ablation by the Lacroix-Zepp technique is done using CO2 laser surgery. Special laser-induced thermotherapy (LITT) can be used in interstitial spaced organs where tumor cells need to be treated. In throat cancer, Neodymium Yttrium Al garnet, popularly known as Ndyag lasers, is used successfully. Some lasers, like argon, only pass the external layer of skin in laser therapy.
