Figure 4: An illustration of inaccurate result of Doppler USG, flap design, and the advantage of freestyle technique. The perforator (green point) is listened by Doppler and the flap design (green ellipse) is made for the defect with reference to this perforator. An illustration of a more suitable perforator (red point) whose exact location cannot be detected by Doppler and the incision which is made for freestyle flap harvesting (red line). In freestyle flap harvesting, the incision is designed in such a way that all perforators can be evaluated without focusing on any perforator location beforehand. The incision can be continued up or down as needed, or the dissection can be directed medially. USG: Ultrasonography
