Keloids, commonly known as scars, are connective tissues that form secondary to healing skin injuries and are characterized by infiltrative, excessive growth beyond the edges of the initial injury. The disease is often secondary to trauma, burns, scalds, earring irritation, injections, and surgery, and is often accompanied by itching and tingling, which affects the patient’s quality of life.
The clinical diagnostic criteria for keloid scars are: 1. the lesion is beyond the initial edge of the skin injury, infiltrating into the surrounding normal tissues and growing in a crabfoot pattern; 2. the growth is continuous and will not subside on its own; 3. it is higher than the surface of the skin, hard and tough, red in color, nodular, striated or lamellar, often accompanied by itching and tingling.
The main treatment modalities for keloid scars are: keloid scars can be treated in a variety of ways, including surgical and non-surgical treatment, and the non-surgical modalities are mainly intra-scar drug injection and radiation therapy, including radioisotope dressing, superficial X-ray therapy, and electron beam therapy from linear gas pedals.
