Paper Abstract

The primary effect of scarring is the loss of function in the affected area. Scarring also leads to physical and psychological problems that could be devastating to the patient’s life. Currently, scar assessment is highly subjective and physician dependent. The examination relies on the expertise of the physician to determine the characteristics of the scar by touch and visual examination using the Vancouver scar scale (VSS), which categorizes scars depending on pigmentation, pliability, height and vascularity. In order to establish diagnostic guidelines for scar formation, a quantitative, accurate assessment method needs to be developed. An instrument capable of measuring all categories was developed; three of the aforementioned parameters will be explored. In order to look at pliability, a durometer which measures the amount of resistance a surface exerts to prevent the permanent indentation of the surface is used due to its simplicity and quantitative output. To look at height and vascularity, a profilometry system that collects the location of the scar in three-dimensions and laser speckle imaging (LSI), which shows the dynamic changes in perfusion, respectively, are used. Gelatin phantoms were utilized to measure pliability. Finally, dynamic changes in skin perfusion of volunteers’ forearms undergoing pressure cuff occlusion were measured, along with incisional scars.
