Abstract

Hypertrophic scars caused by burns represent one of the most common complications of burn trauma, especially in higher degree burns that cause destruction of epidermis a dermis. Normally, the healing process has three phases: inflammatory, proliferative, and remodeling. A more complicated healing process carries with it an exceptionally high risk of causing hypertrophic, movement limiting, and esthetically displeasing scarring. Hypertrophic scars are created within the extent of the primary wound and enter the surrounding skin above the niveau, they are painful, rigid, and itchy, are initially red, and can develop into contractures that require surgery. The following scales are used for clinical evaluation of burn scars and their response to therapy: Patient and Observer Scar Assessment Scale, Visual Analog Scale, Manchester Scar Scale, and the most commonly used, Vancouver Scar Scale, which is based on evaluating pigmentation, height, pliability and scar vascularization. The evaluation of scars using the listed scales is inherently subjective, it depends on the experience and ability of the evaluating physician. This bachelor’s thesis focuses on the methodology of objective evaluation of scar pigmentation and their development over time, based on the data acquired from the designed skin colorimeter. This device will be used for clinical purposes in the burn center of University Hospital Ostrava.
