RESUMEN
Reconstruction of a large scalp defect following oncologic surgical resection is a challenging task. The defect size, location, and elasticity of the soft tissue overlying the calvarium are important factors to be considered when exploring available reconstructive options. When primary closure is not feasible with a large defect, a skin flap or graft is utilized. Skin flap is advantageous as it produces a similar color and texture as the surrounding areas, thus being the favorable method. Wounds involving exposed bone, tendon, and cartilage cannot support grafts due to poor vascularity and thus require a skin flap. One of the multi-flap closure modalities, the Orticochea flap, is an excellent choice for scalp reconstruction on large defects greater than 50 cm2. We present an interesting case of a patient with a large scalp defect following Mohs surgery of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) that was successfully reconstructed with tissue expansion utilizing Orticochea flap, with the addition of an acellular dermal matrix as an adjunct in such hostile scalp reconstruction.
