What are the most effective methods for removing scar hypertrophy?

Principle

Applying pressure to the scar area reduces local blood supply and inhibits the growth and proliferation of scar tissue.

Utilizes selective photothermolysis; specific wavelengths of laser light are absorbed by hemoglobin in the scar tissue.

CO₂ fractional laser creates microscopic thermal injury zones in the scar tissue, stimulating the skin's natural healing and repair mechanisms.

Healthy skin tissue is harvested from another part of the body and transplanted onto the wound site after scar excision.

Skin and subcutaneous tissue with blood supply are transferred to the scarred area.

Indications

All types of hypertrophic scars

Hypertrophic scars that are red in color and firm in texture

All types of hypertrophic scars

Large scar areas that cannot be directly sutured

Hypertrophic scars located in functional areas or those significantly affecting appearance
