Inquiry about the treatment schedule for hypertrophic scar cryotherapy?

Hello Doctor, I previously underwent two sessions each of cryotherapy and electrosurgery for a viral wart.
Ultimately, the electrosurgery resolved the wart, but it left a scar...
which seems to be hypertrophic scarring.
About six months later, I visited the clinic for treatment of the hypertrophic scar, and I have been receiving cryotherapy every two weeks for a total of four sessions.
The affected area (located at the joint of my thumb, smaller than a one-dollar coin) appears to be flat, but the doctor continues with the cryotherapy.
I would like to know how much longer the cryotherapy is needed, or what the typical treatment duration is.
The cryotherapy is really painful...
I would like to understand better, thank you for your clarification.

More Info

Cryotherapy, or cryosurgery, is a treatment method that involves the application of extreme cold to destroy abnormal tissues, such as hypertrophic scars. Hypertrophic scars are raised scars that can develop after an injury or surgery, and they often result from an overproduction of collagen during the healing process. The goal of cryotherapy in treating these scars is to reduce their size and improve their appearance.

The duration and frequency of cryotherapy treatments can vary significantly based on several factors, including the size and location of the scar, the individual’s skin type, and the response to previous treatments. In your case, you mentioned that you have undergone four cryotherapy sessions every two weeks, and the scar appears to be flattening. This is a positive sign, as it indicates that the treatment is having an effect.

Typically, the treatment protocol for hypertrophic scars can range from a few sessions to several months of ongoing treatment. Some patients may require only a few sessions, while others may need more extensive treatment. The decision on when to stop treatment is often based on clinical judgment and the response of the scar to the therapy. If the scar continues to flatten and show improvement, the doctor may decide to taper off the treatments. However, if there is little to no change, the physician may recommend additional sessions.

The pain associated with cryotherapy can be significant, as the procedure involves freezing the tissue, which can cause discomfort. The level of pain experienced can vary from person to person. Some practitioners may use topical anesthetics or cooling agents to help minimize discomfort during the procedure. It’s important to communicate with your healthcare provider about your pain levels and any concerns you have regarding the treatment. They may be able to adjust the technique or provide additional pain management options.

In terms of the expected duration of treatment, while some patients may see significant improvement after just a few sessions, others may require ongoing treatment for several months. It is not uncommon for a treatment plan to extend over a period of 3 to 6 months, depending on the individual’s healing response. Regular follow-up appointments are essential to assess the progress and determine the next steps in the treatment plan.

In conclusion, the duration of cryotherapy for hypertrophic scars can vary widely among individuals. It is crucial to maintain open communication with your healthcare provider regarding your treatment progress and any discomfort you experience. They will be able to provide you with personalized guidance based on your specific situation and help you understand when it might be appropriate to conclude the cryotherapy sessions. Remember, the goal is to achieve the best possible outcome while managing pain and discomfort effectively.

The chances of self-resolution are likely low. It is advisable to consult a dermatologist for treatment. Typically, injections are administered every 2 to 4 weeks depending on the condition, but this only improves the situation rather than completely eliminating it.
