Post-operative radiation therapy planning in the presence of a flap. Dosimetry showing standard coverage (left: upper panel in sagittal view and lower panel in axial view) and flap sparing (right: upper panel in sagittal view and lower panel in axial view; the cranial part of the flap is spared as well as the central part, while the flap–native tissue junction receives full tumor dose) in flap (yellow contour) areas distant from the native tissues at risk of harboring microscopic tumor in a patient with reconstructive anterolateral thigh flap surgery for oral cavity cancer.
