Advances in the research of techniques for traumatic scars intervention with photoelectric acoustic therapy

Traumatic scar is a common complication of skin injury, such as burn, trauma, and surgery. The mechanism for scar formation still remains unclear. Traumatic scar has a negative impact on the quality of patients′ life, due to the appearance of scar always causes physical or/and psychological problems to patients. The treatments for scar include surgery, chemotherapy, radiotherapy, and pressure, depending on the kind of scar present. Recently, a great progress in treating scar has been achieved by novel techniques with laser, intense pulsed light, micro-plasma radiofrequency, and ultrasound. The aim of this review is introducing the advances of these techniques for traumatic scars intervention.
