1540nm Non Ablative Fractional Laser Treatment of Scars

2014-07-23 21:11:00 | BioPortfolio


Scars are a frequent reason of consultation in a dermatological clinic. Their cosmetic aspect can play a key role in patient satisfaction and self-image.

Non ablative fractional infra-red laser treatment is a new concept in the laser field using arrays of microscopic thermal damage patterns to stimulate a wound healing response. There are different reports on the positive effect of these type of laser treatment in the treatment of acne scarring, striae, rythides, hypopigmented and hypertrophic scars.

The low morbidity of the treatment and the lack of satisfying treatment regimes for different types of scars makes it attractive to investigate the efficacy and safety of 4 treatment with the 1540nm non ablative fractional laser in the treatment of scars.


- To evaluate the efficacy of 4 laser treatments with Starlux 300 Lux 1540nm Fractional laser handpiece ( Palomar Medical Technologies ) 1 and 3 month after the last laser treatment for 3 different "scar" patient groups :

1. Patients with hypopigmented scars

2. Patients with hypertrophic scars

3. Patients with scars due to grafts and reconstructions in the head and neck region.

- To evaluate the treatment related pain. on a categorical scale from 0-10

- To evaluate the adverse effect of 1540nm fractional laser versus untreated control in the 3 patient groups.

The study design is a prospective single blinded randomised within-patient controlled study The study involves 6 visits.

Medical and Biotech [MESH] Definitions

A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).

Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.

Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.

The coagulation of tissue by an intense beam of light, including laser (LASER COAGULATION). In the eye it is used in the treatment of retinal detachments, retinal holes, aneurysms, hemorrhages, and malignant and benign neoplasms. (Dictionary of Visual Science, 3d ed)
