article imageNew laser treatments improve mature burn scars

New research suggests that fractional carbon dioxide laser treatment appears to be a promising method for dealing with difficult lesions.
In trials, the use of that fractional carbon dioxide lasers was superior when dealing with persistent erythema (redness of the skin or mucous membranes) when compared with more traditional vascular lasers.
Persistent erythema is a common problem in hypertrophic scars and burn scars. In most cases the condition is treated using vascular lasers (particularly the pulsed dye lasers.)
Vascular Laser light is a high intensity, single wavelength beam. Vascular lasers selectively target and damage unwanted or abnormal blood vessels and are used by dermatologists to treat 'broken capillaries', persistent facial redness, rosacea, burns, scars and vascular (red or purple) birth marks. In terms of how this works: laser light penetrates the outer layers of skin reaching the blood vessels below. Targeted blood vessels soak up all of the energy in the beam and are destroyed by the brief but intense heat. The body removes the damaged tissue naturally and the resulting bruise fades normally.
Where conventional laser resurfacing uses beamlets of energy light to bore tiny holes in the skin, a fractional laser carries this out in a way that prevents damage to the top layer of skin, offering maximum results with a minimal recovery time. The fractional laser can target specific areas with a precision beyond conventional approaches.
New research, where ten patients with mature burn scars completed three treatments with fractional carbon dioxide laser, the results were evaluated to be more successful when compared with conventional laser treatments. The study paves the way for future examinations.
The new study was performed by Research conducted by Karen L. Connolly, M.D., Marsha Chaffins, M.D., and David Ozog, M.D. The research has been published in the journal Lasers in Surgery and Medicine, in a paper titled “Vascular Patterns in Mature Hypertrophic Burn Scars Treated with Fractional CO2 Laser.”
