    Scar stretching and recurrent donor scars have several causes. Ultimately, any skin injury that occurs below the dermal/epidermal junction precipitates a number of cellular metabolic events that trigger the formation of scar tissue.

    Appropriate surgical judgment typically dictates that a donor defect be closed without tension, because tension can increase scarring, damage adjacent hair follicles and even trigger tissue necrosis in and around the lesion. Most surgeons today use a layered technique where the dermis is closed with absorbable sutures. At the skin surface the wound edges are reapproximated with a removable suture material to complete the closure and minimize scar width.

    Recently, wound healing materials have become available that may enhance the outcome in the donor surgical site. In our lab, at various points in time we’ve been involved in the development and testing of such materials.
