"Opposite semilunar" variant of Burow triangle in rotation and advancement flaps

The Burow triangle is an expedient suitably conceived either to facilitate sliding of the flap and avoid folds due to differences in skin distension or to correct coaptation of 2 cutting edges with a different length. In some cases, the triangle cannot be drawn in the right position either because of a particular anatomic site, for example, in proximity to commissures and openings, or because it is contraindicated to avoid unwelcome scar lines. In these cases, a semilunar ablation opposite to the direction of Burow triangle could be a valuable alternative. We report 3 cases where the opposite semilunar variant of Burow triangle was used in critical areas of the face.
