Assess the effect of extracorporeal shock waves on hypertrophy scar

Full description

Prolonged and abnormal scarring after trauma, burns and surgical procedures often results in functional and cosmetic deformities. A wide variety of treatments have been advocated for pathologic scars regression. Unfortunately, the reported efficacy has been variable.Unfocused extracorporeal shock wave therapy is a feasible and non-intensive treatment. And it is an emerging option for the treatment of painful and retracting scars.

Administration of ESWT appears to result in significant improvements in scar clinical appearance, mobility and subjective pain. Clinical data were mirrored by histologic changes in connective tissue appearance and scar vascularization. Extracorporeal shock wave therapy is also an effective and conservative treatment for patients with aesthetic and functional sequela from burn scars. It is a feasible, cost-effective, well-tolerated treatment that can be used in the management of post-burn pathologic scars after the patients are briefed on the practical aspects of the treatment procedure.
