The healing of any trauma to the human skin such as surgical incisions, burns, etc. is accompanied by scar formation to varying degrees. In the process of scar repair, various factors, systemic or local, often lead to excessive proliferation of scar tissue to form hyperplastic scars or scars. Due to the proliferation of scars, some patients experience symptoms such as painful or itchy scars. In particular, scar pain makes it unbearable for patients, and the mechanism by which it arises is not yet clear. One of the possible causes is caused by the stimulating effect of scar proliferation on the damage to sensory nerve endings. This kind of pain is very tricky to treat medically. We conducted an exploratory study on scar pain over a period of 4 years and established a method of radiofrequency ablation for the treatment of scar pain, using a technique that promotes scar absorption. The mechanism of treatment may be the absorption of the scar and the elimination of the compression of sensory nerve endings by the scar.
