Combination of medical needling and non-cultured autologous skin cell transplantation (renovacell) for repigmentation of hypopigmented burn scars in children and young people.
Burn scars remain a serious physical and psychological problem for the affected. Clinical studies as well as basic scientific research have shown that Medical Needling can significantly increase the quality of burn scars with comparatively low risk and stress for the patient with regards to skin elasticity, moisture, erythema and transepidermal water loss. However, Medical Needling has no influence on repigmentation of large hypopigmented scars. The goal is to evaluate whether both established methods - Needling (improvement of scar quality) and ReNovaCell (repigmentation) - can be combined. So far, eight patients with mean age of 20 years (6-28 years) with deep second and third degree burn scars have been treated. The average treated tissue surface was 76cm² (15-250cm²) and was focused on areas like face, neck, chest and arm. Medical Needling is performed using a roller covered with 3mm long needles. The roller is vertically, horizontally and diagonally rolled over the scar, inducing microtrauma. Then, non-cultured autologous skin cell suspension (ReNovaCell) is applied, according to the known protocol. The patients were followed 12 months postoperatively. Pigmentation changes were measured objectively, and with patient and observer ratings. Patient satisfaction/preference was also obtained. We present the final study results. Taken together, pigmentation ratings and objective measures indicate improvement in six of the study participants. Melanin increase seen 12 months after ReNovaCell treatment in the study group as a whole is notable. Medical Needling in combination with ReNovaCell shows promise for repigmentation of burn scars.
