Brief Summary:
This study evaluates the effect of a fractionated carbon dioxide laser on surgical scars of the face and neck over 12 months Anyone with a surgical scar on the face and neck who has not had laser therapy may be eligible to participate The visits occur every three months for up to 12 months Subjects will be randomly assigned to receive a higher energy treatment or a lower energy treatment during the study Subjects and raters will be blinded to which therapy level the patient receives At each visit the scars will be photographed and the subject will complete a questionnaire to rate the scar prior to treatment Three physicians will evaluate the scar at each visit One rater will evaluate the scars in person during the visit while the other two raters will evaluate the scars using photographs after each visit During the first three study visits subjects will receive their assigned treatment obtain post-treatment instructions and a diary to record redness swelling pain itching or other skin changes after treatment At the third study visit subjects will have the option to receive additional treatments or terminate their participation in the study The fourth visit for those who continue will be a treatment visit for one group and the fifth visit will be for data collection with no treatment offered
Detailed Description:
In dermatology the use of Light Amplification by Stimulated Emission of Radiation laser has revolutionized the management of various conditions including angiomas vitiligo wrinkles and scars Omi 2014 and Chapas 2008 Scars result from sub-optimal collagen production during wound healing leading to topographical irregularities To effectively modify these defects any treatment must be capable of penetrating the epidermis and eliciting dermal remodeling at a depth of at least 1 mm The 10600 nm carbon dioxide CO2 laser utilizes high energy at short durations to vaporize intra- and extra-cellular water resulting in tissue ablation causing a substantial thermal injury to the dermis reducing the likelihood of additional scarring The CO2 laser can stimulate collagen production and theoretically improve scar thickness pliability and texture
This study is a prospective randomized double-blinded placebo-controlled trial to evaluate the efficacy of fractionated carbon dioxide laser in improving surgical scars on the head and neck over 3-5 study visits for a duration of 125 months Scar assessments will be based on objective changes identified on pictures taken with the Canfield Vectra M3 3D Imaging System and subjective changes identified with the Patient and Observer Scar Assessment Scale POSAS a validated scar scale As a secondary objective the study will evaluate the tolerability of the laser by assessing the severity and duration of known side effects of laser therapy such as erythema edema burning sensation post-inflammatory pigment changes infection scarring xerosis pruritus bronzing and any other adverse events that arise following treatment Subjects will be given a diary after each treatment to document this information
