Figure 3

(a). DFSP was located in the right nasolabial sulcus. ((b)–(d)) The preoperative 3D tumor model reconstruction. (e) The preoperative surgical design to mark the margin of excision. (f) Excision of the DFSP. (g) The inner part of tumor was debulked, and the outlay was expanded to form planar tissue. (h) The outer layer was cut into small sections and marked for orientation with red, yellow, and green dye. (i) The secondary defect was repaired using an anterolateral thigh-free flap, and this free flap survived.
