DERMATOSURGERY ROUNDS: THE DOUBLE ROTATION (YIN-YANG) FLAP AS BASIC WEAPON IN THE FIGHT AGAINST KERATINOCYTE CANCER...

When opting for reconstruction, every dermatosurgeon should consider several key aspects of the defect being managed - firstly the location and size of the defect, particularly when it is situated in a challenging anatomical region with rich vascularity and innervation. It is also important to consider the potential tension that may be generated and how and in which direction it should be redistributed, as well as the expected aesthetic and functional outcomes. Classical techniques, although not new, have proven to be safe and reliable over time and should always be considered when selecting the most appropriate reconstructive approach. The double (bilateral) opposing rotation (Yin-Yang) flap is a versatile reconstructive technique used primarily in the scalp region for the reconstruction of small-to-medium-sized defects. We present another case of a successfully reconstructed with a Yin-Yang flap, a small-to-medium-sized circular scalp defect following excision of a squamous cell carcinoma. Although the final aesthetic outcome may be suboptimal, this approach remains a preferred option compared with other techniques in terms of effective tension distribution, maintenance of functional anatomy, and preservation of surrounding tissue.
