What is a hypertrophic scar?
Hypertrophic scars develop when the body produces an excessive amount of collagen during the healing process. This results in a raised, thickened scar that protrudes above the skin surface. These scars can be painful, itchy or sensitive and are often cosmetically bothersome. They usually form after operations, burns or other serious skin injuries. Hypertrophic scars are benign and can flatten and fade over time, but this process can take months to years.
How does a hypertrophic scar develop?
Hypertrophic scars develop in response to trauma or damage to the skin, such as deep cuts, burns, surgical incisions or other injuries. During the healing process, the body produces collagen to repair the damaged skin. With hypertrophic scars, too much collagen is produced, making the scar thick and raised. This can be made worse by factors such as infections, tension on the wound or genetic predisposition.
What are the symptoms of a hypertrophic scar?
Hypertrophic scars are usually red, pink or purple in colour and protrude above the skin surface. They can be thick, firm and raised and are often accompanied by itching, pain or sensitivity. Unlike keloids, which can continue to grow, hypertrophic scars remain limited to the boundaries of the original wound. Over time, these scars can gradually decrease in height and colour, but this can take several months to years.
Treatment options for hypertrophic scars
Various treatment options are available for hypertrophic scars, depending on the severity and the aesthetic effect:
- Corticosteroid injections: Steroid injections can help reduce inflammation and make the scar tissue softer and flatter.
- Silicone gel or sheets: Applying silicone regularly can help soften the scars and improve their appearance.
- Pressure therapy: Using pressure dressings can help reduce the height of the scar by limiting collagen formation.
- Laser therapy: Lasers can be used to improve the colour and texture of the scar by reducing the scar tissue and stimulating the skin.
- Surgical revision: In some cases, surgical removal or correction of the scar may be necessary, followed by careful aftercare to prevent new hypertrophic scarring.
When is treatment for a hypertrophic scar needed?
Treatment for hypertrophic scars may be needed if the scar is cosmetically bothersome, causes pain or discomfort, or restricts the movement of a joint or other part of the body. The choice of treatment depends on the size, location and severity of the scar, as well as the patient's preferences. Some hypertrophic scars can improve on their own without treatment, but this can take a long time. Patients who are bothered by their scars should consult a doctor to discuss the best treatment options.
The difference between hypertrophic scars and keloids
The main difference between hypertrophic scars and keloids is that hypertrophic scars remain limited to the boundaries of the original wound, whereas keloids grow beyond these boundaries and spread into the surrounding skin. Hypertrophic scars are often less severe than keloids and are more likely to flatten and fade over time, whereas keloids usually continue to grow unless they are treated.
Risks and considerations
Although hypertrophic scars are generally benign, they can cause discomfort and be cosmetically bothersome. It is important to choose a treatment plan tailored to the specific characteristics of the scar and the needs of the patient. Some treatments, such as corticosteroid injections or surgical procedures, can have side effects, such as skin discolouration, thinning of the skin or infection. Patients should be well informed about the pros and cons of each treatment option and the expected results.
Conclusion
Hypertrophic scars are abnormally raised scars that develop due to excessive scar formation during the skin's healing process. Although they usually stay within the boundaries of the original wound, they can be cosmetically bothersome and sometimes painful. Various treatment options are available to reduce the appearance and symptoms of hypertrophic scars. It is important to choose the right treatment based on the specific characteristics of the scar and to consult an experienced doctor for the best care and results.
