Keloids and raised scars can be challenging for individuals both cosmetically and psychologically. Dermatologists employ various methods to manage and treat these conditions, depending on their size, location, and the patient’s preferences. Here’s an overview of the treatment options available for keloids and raised scars.
Understanding Keloids
Keloids are a type of thick, raised scar that occurs when the skin heals after an injury. They can be larger than the original wound and may continue to grow over time. Keloids are more common in individuals with darker skin tones, and while they are generally harmless, they can be itchy, painful, or bothersome due to their appearance.
Treatment Options
1. Intralesional Steroid Injections
One of the most common treatments for keloids is the injection of corticosteroids directly into the scar tissue. This method helps to flatten the keloid and reduce inflammation. Multiple sessions may be required, spaced several weeks apart. Patients often see gradual improvement, but complete resolution is rare. This treatment is effective for smaller keloids and can help prevent further growth.
2. Surgical Excision
For larger keloids, surgical removal may be considered. During this procedure, the dermatologist excises the keloid tissue. However, there is a risk of the keloid returning, sometimes even larger than before. To mitigate this risk, surgeons often combine surgical excision with other treatments, such as steroid injections or radiation therapy.
3. Cryotherapy
Cryotherapy involves freezing the keloid with liquid nitrogen, causing the scar tissue to shrink. This method is often used for smaller keloids and is typically combined with other treatments, like steroid injections, to enhance effectiveness. Cryotherapy can be uncomfortable, and multiple sessions may be needed to achieve optimal results.
4. Silicone Gel Sheets or Dressings
Silicone gel sheets are a non-invasive option for managing raised scars. These sheets are placed over the keloid and can help flatten the scar over time by hydrating the area and creating a protective barrier. Patients usually wear the silicone sheets for several hours daily over a period of weeks to months to see results.
5. Laser Therapy
Laser treatments can effectively reduce the size and redness of keloids. Dermatologists may use pulsed dye lasers or fractional lasers to target the scar tissue. Laser therapy can also improve the texture of the skin. Like other treatments, multiple sessions are typically required, and results can vary based on the individual.
6. Radiation Therapy
Post-surgical radiation therapy can be an effective preventive measure against keloid recurrence. This approach is often used in conjunction with surgical excision to minimize the chances of the keloid returning. It involves applying a low dose of radiation to the scarred area shortly after the keloid is removed.
7. Combination Therapy
In many cases, dermatologists recommend a combination of treatments to achieve the best results. For instance, a patient may undergo surgical excision followed by steroid injections or laser therapy to enhance the outcome and reduce the likelihood of recurrence.
Conclusion
Treating keloids and raised scars requires a personalized approach, as each patient may respond differently to various treatments. Dermatologists consider factors such as the keloid's size, location, and the patient’s skin type before recommending a treatment plan. While complete removal of keloids can be challenging, many effective options are available to minimize their appearance and improve the patient's quality of life. For those struggling with keloids or raised scars, consulting a dermatologist can help identify the most suitable treatment strategy tailored to individual needs.
