Evaluation the improvement of skin hardness and flexibility in Facial Atrophic Scars Treatment with Automated Micro Needling

Abstract

Background and Aim of study: Scar formation is a natural part of the healing process following a physical injury to body tissues. The most common type of scars are atrophic scars. These pathological scars result from an abnormal response to trauma. They can be painful and itchy leading to a considerable functional and aesthetical disability. Post-surgical scars require a complex treatment and can be very challenging for surgeons.

Aim of The Study: To evaluate the hardness and flexbilty satisfaction of surgeons and patients regarding the aesthetical results following the application of the Automated Micro-Needling  Technology.

Material And Methods: The study evaluates 18 scars from 10 patients: 6 males (13 scars) and 4 female  (5 scars) aged between 18 and 36. The patients were treated using the Automated Micro-Needling  Technology at three stages of healing with intervals of 20 days. Using the Patient and Observer Scar Assessment Scale V2.0 (POSAS), each scar has been evaluated from the patients’ scale in terms of pain, itchiness, skin color, hardness, thickness, shape and the state of the abnormal facial scar. The same abnormal facial scars have been evaluated by three different observers in terms of vascularity, pigmentation, thickness, relief, pliability, surface area and the overall state of the scars using the POSAS doctor’s scale at four distinct stages. Clinical evaluation of the results was performed.　

Results:  Under 70 N molar loading, the OD method showed the least displacement, and the OD

method showed the least Von Mises stress in the screw plating system.　

Conclusion : The Automated Micro-Needling Technology leads to a significant improvement in the characteristics of the atrophic scars.
