Treatment for Keloid Scarring
Effective treatment for Keloid scarring
Different kinds of Keloid treatments nowadays cannot totally prevent the growth of scarring tissues, it may stimulate the keloid to grow back, and may even develop into a bigger keloid. In recent years, U.S. Food and Drug Administration (FDA) has verified the therapeutic efficacy of "Cryosurgery" on Keloids treatment, which overcomes the limitations of traditional and conventional treatment methods.
By damaging cells with the change in temperature, the destroyed cells will scab and fall off, thereby reducing recurrence rate. In fact, "Cryosurgery" has already been used in the early 1970s and 1980s to eliminate Keloids by contacting with liquid nitrogen. Medical professionals then started to investigate on the application of CryShape to treat Keloid and scarring tissues.
"Cryosurgery" treatment takes around 10-60 minutes, depending on the size and location of the keloid. Local anesthesia will be performed before the treatment. During surgery, the doctor will first insert a needle into the Keloid, liquid nitrogen of very low temperatures contained will then be injected. The scar will rapidly decrease in temperature, causing the cells to crystallize, dehydrate and finally be frozen and destroyed.
The doctor will stop injecting liquid nitrogen at suitable time in order to let keloid thaw. After surgery and wound dressing, patients can return to daily activities without the need of hospitalization. Under normal circumstances, the wound can be recovered in 2 to 4 weeks and the destroyed cells will scab and fall off.
After surgery, patients may experience different levels of pain, red spots, subcutaneous edema, subcutaneous hemorrhage and pigmentation, as well as other conditions. Most of these conditions will completely disappear. Therefore, patients must clean their wounds and keep them dry in order to prevent infections.
General surgical risks include sensitive to anesthetics, wound infection etc.
