Hypertrophic Scar Treatment
Hypertrophic scars are raised scars that form due to excessive collagen production during the wound-healing process. Treatment options focus on reducing the scar’s size, improving its appearance, and relieving associated symptoms like itching or discomfort. Here’s a breakdown of commonly used treatments:
1. Non-invasive Treatments
Silicone Sheets or Gels
- How it works: Silicone helps hydrate the skin and regulate collagen production.
- Usage: Apply to the scar daily for several hours over several weeks to months.
Pressure Therapy
- How it works: Pressure garments or bandages can flatten the scar.
- Usage: Often used for burns or larger scars, requiring consistent wear.
Topical Treatments
- Ingredients: Vitamin E, onion extract (e.g., Mederma), or hydrocortisone creams.
- Effectiveness: May help with scar texture and itching but have limited impact on raised scars.
2. Minimally Invasive Procedures for Hypertrophic Scars
Corticosteroid Injections
- How it works: Reduces inflammation and collagen production.
- Frequency: Injections every 4-6 weeks until the scar flattens.
- Results: Effective for reducing scar height and improving symptoms.
Laser Therapy
- Types: Fractional CO2, pulsed dye laser (PDL).
- Purpose: Smoothen the scar, reduce redness, and flatten the tissue.
- Sessions: Multiple treatments may be required.
Cryotherapy
- How it works: Freezing the scar tissue can shrink and soften it.
- Ideal for: Small scars; sometimes combined with corticosteroids.
3. Surgical Options
Scar Revision Surgery
- What it does: Removes the scar tissue and re-sutures the skin.
- Consideration: Risk of new scar formation; often combined with other treatments like silicone or pressure therapy post-surgery.
4. Advanced Therapies
Microneedling
- How it works: Creates micro-injuries to stimulate collagen remodeling.
- Combination: Often paired with serums or platelet-rich plasma (PRP).
Radiotherapy
- Use: Low-dose radiation is sometimes used post-surgery to prevent recurrence of hypertrophic scars.
- Caution: Reserved for severe cases due to potential side effects.
