Advances in laser techniques used in medicine significantly expanded the pool of procedures as well as increased the frequency and ease of their use. Paediatric surgery is one of the branches of medicine open to use the dynamically developing laser technologies. Based on the current literature and our own experiences, we present a cross-sectional review of modern applications of laser therapy in the paediatric population. Laser therapy is often used complementary to other treatment methods and, in many cases, it becomes the main treatment approach in a variety of conditions. It is an indispensable element in the management of many diseases, both those health- and life-threatening as well as those responsible for cosmetic defects directly contributing to reduced quality of life of patients. This allows for a very short recovery time, with a low risk of adverse effects. The method is gaining popularity and is continuously improved. It is used, among other things, in the management of congenital and acquired vascular lesions, pilonidal sinuses, and scars. Undoubtedly, the future use of laser therapy in paediatric surgery will definitely expand to include further disease entities. A brief overview of therapeutic options for conditions in which laser therapy has become the leading therapeutic strategy can help general practitioners and paediatricians choose the optimal treatment strategy for their patients. Raising the awareness of general practitioners of indications for laser therapy may bring significant benefits for paediatric patients. Laser is becoming an increasingly available tool, which, considering the efficacy of laser therapy and a large number of indications, encourages referring patients to specialists performing such procedures.
