Abstract:
There is a wide spectrum of treatment modalities to manage hypertrophic scars, techniques like surgical excision, intralesional application of corticosteroids, pressure therapy or laser therapy are extensively used.From a cosmetic and physiological point of view scars are predominantly a concern of the patients, the cosmetic relevance for doctors is often of less importance. Therefore a treatment that can be performed by the patient her-/himself might be advantageous if it is efficacious and safe. Since the early 1980s so-called “silicone gel sheeting” has been a widely used safe clinical management option for hypertrophic scars and keloids.The principle of the latter treatment has now been adapted and optimised towards a specific easily applicable adhesive polyurethane patch. This breathable, hypoallergenic patch is very well tolerated and avoids - in contrast to silicone sheets - moisture accumulation on the skin. Several clinical studies on both mature scars and on scar formation after surgical incisions show a reduction in visibility, redness, and roughness of the scars. The recommended eight weeks treatment might even be interrupted daily for twelve hours; the scar reducing effect is achieved as well.Extensive investigations on the polyurethane patch in vivo and in vitro propose an improved remodelling process of the scar tissue due to thermal and pressure effects of the patch but not by stratum corneum hydration. In vivo a better microcirculation can be observed in the scar tissue after treatment and in vitro an activation of enzymes involved in the remodelling process can be measured.In summary, physical effects are likely to be responsible for the successful results in clinical studies and individual applications of the new polyurethane patch for the reduction of hypertrophic scars.Document Type: Abstract
