KELOIDS AND HYPERTROPHIC SCARS

Keloids and hypertrophic scars are abnormalities in the normal wound healing characterized by greater and more sustained extracellular matrix deposition that develops after any insult in the dermis.

It can affect the patient's quality of life, both physically and psychologically.

Hypertrophic scars are raised fibrous tissue scars that remains within the boundaries of the wound. Hypertrophic scars that resulted from surgery or trauma are called linear hypertrophic scars while those from burn injuries or extensive tissue trauma and/or infections are called widespread hypertrophic scars.

Keloids are elevated fibrous scars that extend beyond the borders of the original wound. Major keloids resulted from minor trauma while for those from genetic predisposition with autosomal-predominant features are called minor keloids.

 

 

Surgical Intervention

  • If neither silicone nor intralesional corticosteroids are effective after a year of treatment, scar excision should be considered
  • Z-plasty &W-plasty are the surgical techniques appropriate for reducing scar tension thus reducing the risk of recurrence
  • There are also favorable results in the use of S-plasty surgical technique in long, linear hypertrophic scar reconstruction
  • For larger scars, skin graft or local flaps may be used
