Treatment of Surgical Scars With Fractional Photothemolysis Versus Pulse Dye Laser

Study Overview
=================
Brief Summary
-----------------
Evaluate the efficacy of the Fraxel SR laser to improve the cosmetic appearance of surgical scars, both in terms of pigmentary and textural changes. Evaluate the efficacy of the V-Beam Pulse Dye laser, a standard non-ablative laser which is utilized for the treatment of the erythematous and telangiectasia component of surgical scars. Comparison of the outcome of the half of the surgical scar treated with Fraxel SR laser versus the outcome of the contralateral half of the surgical scar which will be treated with the V-Beam Pulse Dye Laser.

Detailed Description
-----------------
RATIONALE FOR THE PROJECT Surgical scars are a challenging condition to treat. The aesthetic outcome of surgical scars is of great importance to patients and physicians after reconstructive surgery. The current approaches for the treatment of surgical scars range from non-invasive approaches to aggressive treatments with re-excision or ablative resurfacing lasers. Fractional photothemolysis is a new technology whereby only microthermal zones of injury to the skin are created which triggers the wound healing response, leading to skin repair mechanisms to improve the appearance and textural changes associated with surgical scars. Fractional photothemolysis (Fraxel SR laser, Reliant technologies, Inc) is a new technology whereby only microthermal zones of injury to the skin are created which triggers the wound healing response, leading to skin repair mechanisms to improve the appearance and textural changes associated with surgical scars. Fractionated resurfacing, with its significant proven efficacy in improving textural and pigmenatary abnormalities with a benign side effect profile, represents a promising novel treatment for surgical scars. Aim: Comparison of the outcome of the half of the surgical scar treated with Fraxel SR (Reliant Technologies, Inc.) laser versus the outcome of the contralateral half of the surgical scar which will be treated with the V-Beam Pulse Dye Laser SIGNIFICANCE: The cosmetic outcome of surgical scars is of paramount importance to surgeons and patients treated with both cosmetic and reconstructive surgery. It is impossible for surgeons to predict the wound healing properties of individual patients and particular anatomic sites and thus, there is little certainty that can be offered to patients about the cosmetic outcome of their surgical scars. SUBJECTS IN THE PROJECT: Inclusion Criteria: For inclusion, the subject must: Be at least 18 years old; Be otherwise healthy; Be treated by Dr. Kouba for a skin cancer surgery or plastic surgery procedure Agree to attend up 6 sessions post Mohs surgery (2-4 laser treatment sessions and 2 follow-up visits post-laser) Be able to understand the requirements of the study, the risks involved, and be able to sign the informed consent form; Agree to follow and undergo all study-related procedures. Exclusion criteria: A. Patients who do not meet the criteria above and/or who fail to follow their post-operative instructions or make both of their post-operative clinic appointments. B. The control for this study will be the side of the scar treated with the V-Beam Pulse Dye Laser C. We will be speaking to patients at Henry Ford Dermatology regarding participation in our study. We will ensure that all patients understand the voluntary nature of their participation in the study. They will sign informed consent. In addition, we will be asking patients to give us their assessment of which side of their surgical wound had better improvement, the side treated with Fraxel laser versus the side treated with V-Beam Pulse Dye Laser. PROJECT DESIGN AND PROCOTOL: A comparison trial of surgical scars treated with Fraxel SR Laser (Reliant Technologies, Inc.) versus V-Beam Pulse Dye Laser (Candela Corporation) in 15 patients who underwent Mohs surgery and resultant cosmetic surgical reconstruction at Henry Ford Health System Department of Dermatology. At a minimum of 2 months post surgical reconstruction, patients will be eligible for inclusion in this research study. During each 2 weeks of the study, one side of the surgical scar will be treated with Fraxel SR (Reliant Technologies, Inc.) and the other half will be treated with the V-Beam Pulse Dye Laser (Candela Corporation) for aesthetic improvement of the scar
