Minimally invasive technologies for treatment of HTS and keloids : fractional laser

Hypertrophic fractional laser and keloid scars present a spectrum of disorders that are difficult to treat. Multiple treatments have been tried, to ameliorate the clinical sequelae of scarring, such as erythema, pruritus, functional limitation, reduced range of movement, dyschromias, hyper and/or hypopigmentation. Early international clinical recommendations on scar management first recognized the importance of laser therapy in this armamentarium [1]. Within the years that followed, laser technology and the understanding of how it modulates the underlying processes that leads to hypertrophic and keloid scarring have experienced a quantum leap [2] and are still evolving. Lasers also present a considerable financial commitent, and it is possible, in the authors’ experience, that limited early results partially stemmed from limited availability of multiple lasers with consequent attempts to overstretch the indications for what was available. This chapter presents a state-of-the-art insight into the use of fractional laser for the management of this complex problem. In particular, we focus on the management of complex scars such as those occurring post-burn injury and split-thickness skin grafting.peer-reviewe
