Cryotherapy for Scar Treatment: What to Expect

Cryotherapy

Dr.
Wu: Hello, I have a scar on my chest caused by an injury, and there is some hard tissue beneath the scar that underwent cryotherapy.
I have a few questions: 1.
After the treatment, the doctor told me that she didn't spray much, so there wouldn't be any blisters; it would only soften the scar and wouldn't cause any scabbing.
I was advised to return for a follow-up in two weeks, and if the hardness of the scar hasn't changed, we would consider steroid injections.
Isn't it typical for cryotherapy to form a layer of black scab that eventually falls off? Was this cryotherapy effective? 2.
Currently, the area around the wound feels a bit painful.
Does this indicate damage to the epidermal layer of the skin? If the skin hasn't shed a layer, should I use other medications or methods to promote peeling (such as applying fruit acids or asking the doctor to spray more)? I don't distrust the doctor; I just have genuine concerns and am unsure whether I should consult another physician or if I should leave it alone.
Will the injured epidermal layer heal on its own? I apologize for the disorganized questions.
Thank you.

You should consult your attending physician about this issue.
Without actually seeing the lesion, it is impossible to determine the problem.
If it is causing you significant distress, please seek medical attention as soon as possible.
Only after an examination can the issue be identified and addressed.

More Info

Cryotherapy, or cryosurgery, is a treatment method that uses extreme cold to destroy abnormal tissues, including scars. It is often employed to treat various skin conditions, including hypertrophic scars and keloids. Understanding what to expect from cryotherapy for scar treatment can help alleviate concerns and set realistic expectations for recovery.

1. Effectiveness of Cryotherapy: In your case, the physician indicated that the cryotherapy was applied in a controlled manner, with the intention of softening the scar tissue without causing significant damage to the surrounding skin. The absence of blistering or scabbing is a positive sign, suggesting that the treatment was effective in targeting the scar tissue without causing excessive injury to the epidermis. The goal of cryotherapy is to induce a localized inflammatory response, which can help remodel the scar tissue over time. It may take several weeks to see noticeable changes, as the body gradually absorbs the treated tissue and replaces it with healthier skin.

2. Pain and Sensitivity: Experiencing some tenderness or discomfort in the area post-treatment is not uncommon. This can be attributed to the inflammatory response initiated by the cryotherapy. The skin's outer layer may be sensitive, but if there is no visible damage such as peeling or blistering, it is likely that the skin will heal naturally. The epidermis typically regenerates quickly, and any minor irritation should resolve without intervention. However, if the pain persists or worsens, it would be prudent to consult your physician for further evaluation.

3. Follow-Up Treatment: If after two weeks there is no improvement in the hardness of the scar, the physician may recommend corticosteroid injections. These injections can help reduce inflammation and flatten the scar. It’s important to follow your physician's advice regarding follow-up treatments, as they will assess the scar's response to cryotherapy and determine the best course of action.

4. Alternative Treatments: If you are concerned about the effectiveness of the cryotherapy or if you feel that additional treatment is necessary, it is entirely reasonable to seek a second opinion. Other treatments for scars include silicone gel sheets, pressure therapy, laser therapy, and chemical peels. Each of these options has its own set of benefits and potential side effects, and a dermatologist can help you navigate these choices based on your specific scar type and skin condition.

5. Self-Care and Monitoring: In the meantime, it is advisable to keep the area clean and moisturized. Avoiding harsh chemicals or abrasive treatments on the scar is crucial until the skin has fully healed. If you notice any signs of infection, such as increased redness, swelling, or discharge, you should seek medical attention promptly.

In summary, cryotherapy can be an effective method for treating scars, and while some discomfort is normal, it is essential to monitor the healing process. If you have ongoing concerns or if the scar does not improve, do not hesitate to discuss further treatment options with your healthcare provider. Your skin's health is paramount, and open communication with your medical team will help ensure the best outcomes.

Cryotherapy can potentially lead to scarring, and it may not always be avoidable. The actual situation depends on the specific case; if there are atrophic scars, fractional laser treatment can be used.
