Abstract:
Local flaps have the advantages of texture matching and increased flap survival rate. The proper local flap planning for each lesion causes the dermatologist to be reluctant to employ them. We propose a modified local flap, the "Cassiopeia flap", with three simple marking points made on the ends of the diameter and on the equidistant point along the diameter; two points from equilateral triangles form a "W (Cassiopeia)". We applied this modification to ten lesions on the face, scalp, trunk and thigh with excellent results.
