When treating with lasers, why is tissue cooling important?

Tissue cooling is crucial when using lasers primarily to minimize thermal damage. During laser therapy, the laser energy may increase the temperature of the targeted tissues. If these tissues are overheated, it can lead to unintended thermal injury, which may cause pain, inflammation, or even necrosis. Therefore, using cooling methods helps regulate the temperature of the area being treated, ensuring that the laser energy effectively targets the intended tissues while protecting surrounding healthy structures.

Maintaining optimal tissue temperature not only enhances the patient's safety but also improves clinical outcomes by allowing for more precise and effective treatment. Cooling methods can include air cooling, direct contact cooling, or the application of cooling gels, all of which work to draw heat away from the tissue being treated. This approach ensures that the benefits of the laser treatment are maximized while minimizing adverse effects.
